Pampers reacted to FrieChamp for an article, Finding your own path as a professional Level Designer
The following article contains quotes from interviews with Todd Papy, Design Director at Cloud Imperium Games, Geoffrey Smith, Lead Game Designer at Respawn Entertainment, Paul Haynes, Lead Level Designer at Deep Silver Dambuster Studios and Sten Huebler, Senior Level Designer at The Coalition. A big heartfelt 'thank you' goes out to these guys who took the time out of their busy schedules to answer my questions!
On the MapCore.org forums many amateur level designers ask for feedback on their portfolios or for advice on how to break into the games industry. But once you have signed your first contract and you have your foot in the door you will realize that this step marks merely the beginning of your journey. It is a winding path with many diverging branches and without much information available on the road ahead. This is the reason why I decided to interview professional designers in Senior, Lead or Director positions to share their personal experiences and advice with others trying to navigate this field. It is worth mentioning that the questions were not selected and phrased with the goal in mind to compile a ‘how to get promoted fast’ guide. Instead I wanted to give level designers insights into the careers of others - who have stood at the same crossroads before - in hopes that they get the information to pick the path that is right for them.
Hands-On VS Management
At the beginning of his career, Todd Papy started out as a “designer/environment artist” – a job title that dates back to times when team sizes were much smaller and one person could wear both hats at the same time. As the project complexity and team size grew, he specialized in level design at SONY Santa Monica and worked on the God of War titles. During his time there he moved up the ranks to Lead Level Designer, Design Director and eventually Game Director. From level design to directing a game - a career thanks to careful long-term planning and preparation? “It wasn’t even on my radar” says Todd. “I just wanted to build a game with the team and soak up as much information from the people around me as possible.”
So how do level designers feel who step into positions where the majority of their daily work suddenly consists of managing people and processes? Do they regret not doing enough hands-on-work anymore? Todd says he misses building and crafting something with his hands, but instead of going back to his roots, he decided to look at the issue from a fresh perspective: “As a Lead or Director, your personal daily and weekly satisfaction changes from pride in what you accomplished to pride in what the team has accomplished.“ Today Todd is designing the universe of 'Star Citizen' as Design Director at Cloud Imperium Games.
Geoffrey Smith - who created some of the most popular multiplayer maps in the Call of Duty and Titanfall series and who is now Lead of the ‘Multiplayer Geometry’ team at Respawn Entertainment - says his output of levels remains unchanged thus far, but he can “easily see how being so tied up with managing would cut into someone's hands-on work”. Geoffrey calls for companies to provide the necessary training to employees new to management positions: “Managing people and projects is hard work and is normally a vastly different skill set than most of us in games have. Maybe that is why our industry has such problems with meeting deadlines and shipping bug-free games. A lot of guys work for a long time in their respective disciplines and after many years they get moved into a lead position. They certainly know their craft well enough to teach new guys but managing those guys and scheduling would be something brand new to them. Companies need to understand this and get them the training they need to be successful.” At Respawn Entertainment, the studio provides its department leads with training seminars, which helps the staff immensely, according to Geoffrey.
Sten Huebler, currently working as a Senior Level Designer at Microsoft-owned The Coalition, in Vancouver, says he definitely missed the hands-on work when he worked in a Lead capacity on 'Crysis' and 'Crysis 2': “I was longing for a more direct creative outlet again. That is why coming to The Coalition and working on Gears of War 4, I really wanted to be hands on again.” To Sten it was the right move because he enjoyed working directly on many of the levels in the game’s campaign and could then experience his fruit of labour with others close to him: "After Gears 4 shipped, playing through the campaign, through my levels with my brother in co-op was a blast and a highlight of my career. He actually still lives in Germany. Being able to reconnect with him, on the other side of globe, playing a game together I worked on...So cool!"

Paul Haynes, Lead Level Designer at Deep Silver Dambuster Studios, encourages designers to negotiate the amount of organizational tasks and hands-on work before being promoted into a position that makes you unhappy: “I always told myself that I wouldn’t take a Lead position unless it could be agreed that I retain some hands-on, creative responsibility, after all that’s where I consider my strongest attributes to lie. I agreed to both Lead positions (Cinematic/Level Design) under that principle - I never understood the concept of promoting someone who is good at a certain thing into a position where they potentially don’t get to do that thing anymore, as they spend all their time organising others to do it. So far I’ve managed to maintain that creativity to some degree, though I would imagine it’s never going to be quite the same as it used to be, as I do have a team to manage now. On the flip side though, being able to control and co-ordinate the level design vision for a project and having a team to support in fulfilling that is quite an exciting new experience for me, so not all the organisation and planning is unenjoyable.”
Specialization VS Broadening Skillsets
For the level designers who aren’t afraid of management-related tasks and who are willing to give up hands-on work for bigger creative control, what would the interviewees recommend: specialize and strengthen abilities as an expert in level design further or broaden one’s skillset (e.g. getting into system design, writing etc.)? Paul believes it doesn’t necessarily have to be one or the other: “I think it’s possible to do both (strengthening abilities and broadening skillsets) simultaneously, it would really depend on the individual involved. I would say that a good approach would be to start with the specialisation in your chosen field and then once you feel more comfortable with your day to day work under that specialisation, take on work that utilises different skillsets and experiment to see if you find anything else you enjoy.” He started out as a pure level designer but subsequently held roles that involved game and cinematic design at Codemasters, Crytek and Dambuster Studios. “I’ll always consider myself a level designer at heart”, says Paul, “though it’s been incredibly beneficial for me to gain an understanding of multiple other disciplines, as not only has it widened my personal skillset but it has enabled me to understand what those disciplines have to consider during their day to day job roles, and it has helped me to strengthen the bond with those departments and my level design department as a result.” This advice is echoed by Todd who encourages level designers to learn about the different disciplines as “that knowledge will help solve issues that arise when creating a level.”

Sten also gained experience in related disciplines but ultimately decided to return to his passion and do level design. He explains: “It’s a good question and I feel I have been wondering about this myself regularly in my career. I think those priorities might change depending on your current situation, your age, your family situation, but also depending on the experience you gain in your particular field. (…) In my career, I was fortunate enough to try out different positions. For example, I was a Level Designer on Far Cry (PC), Lead Level Designer on Crysis 1 and Lead Game Designer on Crysis 2. Each position had different requirements and responsibilities. As a Lead Level Designer I was more exposed to the overall campaign planning and narrative for it, while on Crysis 2 I was more involved in the system design. However, my true passion is really on the level design side. I love creating places and spaces, taking the player on a cool adventure in a setting I am crafting. My skills and talents also seem to be best aligned on the level design side. I love the combination of art, design, scripting and storytelling that all come together when making levels for 1st or 3rd person games.”
Picking The Right Studio
As you can certainly tell by now, all of the interviewees have already made stops at different studios throughout their career. So each one of them has been in the situation of contemplating whether to pass on an offer or put down their signature on the dotted line. This brings up the question what makes them choose one development studio over the other? To Geoffrey it depends on what stage of your career you are in. “If you're trying to just get into the industry for the first time, then cast your net wide and apply to a lot of places. However, ideally, someone should pick a studio that makes the types of games they love to play. Being happy and motivated to work every day is a powerful thing.”
This is a sentiment that is shared by all interviewees: the project and team are important aspects, but as they have advanced in their career other external factors have come into play: “It’s not just about me anymore, so the location, the city we are going to live in are equally important.” Sten says.
Paul is also cautious of moving across the globe for a new gig. “The type of games that the company produces and the potential quality of them is obviously quite important – as is the team that I’d be working with and their pedigree. More and more over the years though it’s become equally important to me to find that balance between work and life outside of it. Working on games and translating your hobby into a career is awesome, but it’s all for nothing if you can’t live the life you want around it.”
And it is not just about enjoying your leisure time with family and friends, but it will also reflect in your work according to Todd: “If my family is happy and enjoys where we live, it makes it a lot easier for me to concentrate on work.” He also makes another important point to consider if you are inclined to join a different studio solely based on the current project they are working on: “The culture of the studio is extremely important. I consider how the team and management work together, the vibe when walking around the studio, and the desk where I will sit. Projects will come and go, but the culture of the studio will be something that you deal with every day.”

But it goes the other way around, too: When it comes to staffing up a team of level designers, these are the things that Todd looks for in a candidate: “First and foremost, I look for level designers that can take a level through all of the different stages of development: idea generation, 2D layouts, 3D layouts, idea prototyping, scripting, tuning, and final hardening of the level. People that can think quickly about different ideas and their possible positive and negative impacts. They shouldn’t get too married to one idea, but if they feel strongly enough about that specific idea they will fight for it. People that approach problems differently than I do. I want people that think differently to help round out possible weaknesses that the team might have. People who will look for the simplest and clearest solution vs. trying to always add more and more complexity.“
For lead positions, it goes to show yet again how important a designer's professional network is, as Todd for example only considers people that he already knows: “I try to promote designers to leads who are already on the team and have proven themselves. When I am building a new team, I hire people who I have had a personal working relationship before. Hiring people I have never worked with for such positions is simply too risky.”
Ups & Downs
While the career paths of the designers I interviewed seem pretty straightforward in retrospect, it is important to note that their journeys had their ups and downs as well. For instance Geoffrey recalls a very nerve-wracking time during his career when he decided to leave Infinity Ward: “We had worked so hard to make Call of Duty a household name but every day more and more of our friends were leaving. At a certain point it just wasn't the same company because the bulk of the people had left. The choice to leave or stay was even giving me heart palpitations. (…) After I left Infinity Ward, I started working at Respawn Entertainment and by work I mean - sitting in a big circle of chairs with not a stick of other furniture in the office - trying to figure out what to do as a company.” But he also remembers many joyful memories throughout his career: Little things like opening up the map file of multiplayer classic ‘mp_carentan’ for the first time or strangers on the street expressing their love in a game he had worked on. To him, shipping a game is a very joyful experience by itself and the recently released Titanfall 2 takes a special place for him. “The first Titanfall was a great game but we had so many issues going on behind the scenes it felt like we weren't able to make the best game we were capable of. (…) After all the trials and tribulations of starting a new game company, Titanfall 2 is a game I am very proud to have worked on.”

As a response to the question of what some of the bigger surprises (good or bad) in his career have been thus far, Paul talks about the unexpected benefits of walking through fire during a project’s development and the lessons he learnt from that: “It surprised me how positively I ended up viewing the outcome of the last project I worked on (Homefront: The Revolution). I’d always thought I would aim to work on big, successful titles only, but I guess you don’t really know what’s going to be a success until it’s released. Obviously it was a disappointing process to be part of, and a lot of hard work and effort went into making it, despite the team always knowing that there were some deep lying flaws in the game that weren’t going to be ironed out. We managed to ride the storm of the Crytek financial issues in 2014, coming out on the other side with a mostly new team in place and yet we carried on regardless and managed to actually ship something at the end of it, which is an achievement in itself. I see the positives in the experience as being the lessons I learnt about what can go wrong in games production which stands me in good stead should I decide to take a more authoritative role somewhere down the line. Sometimes the best way to learn is through failure, and I don’t believe I’d be as well rounded as a developer without having experienced what I did on that project.”
Last Words Of Advice
At the end I asked the veterans if they had any pieces of advice they would like to share with less experienced designers. To finish this article I will quote these in unabbreviated form below:
Geoffrey: “I guess the biggest thing for guys coming from community mapping is figuring out if you want to be an Environment Artist or a Geo-based Designer and if you want to work on Single-Player or Multiplayer. Each has its own skills to learn. I think a lot of guys get into mapping for the visual side of things but some companies have the environment artists handle the bulk of that work. So figuring out if making the level look great is more enjoyable to you or thinking it up and laying it out is, will help determine which career you should follow. Other than that, just work hard and always look to improve!”
Todd: “BUILD, BUILD, BUILD. Have people play it, find out what they liked about it and what they didn’t. Build up a thick skin; people will not always like your ideas or levels. Try out new ideas constantly. What you think looks good on paper doesn’t always translate to 3D. Analyse other games, movies, books, art, etc. Discover what makes an idea or piece of art appeal to you and how you can use that in your craft.”
Paul: “The games industry is not your regular nine to five job, and everyone is different so it’s difficult to lay down precise markers for success. Different specialisations have different requirements and you can find your choices leading to different routes than your fellow team members. You need to make sure you carve your own path and try everything you can to achieve whatever your personal goals are within the role; success will come naturally as a result of that. You need to be honest with yourself and others, open to criticism and willing to accept change. I’ve seen potential in people over the years hindered by stubbornness, succeeding in the games industry is all about learning and constantly adapting. Also it’s important to keep seeing your work as an extension of a hobby, rather than a job. The moment it starts to feel like a means to an end, you need to change things up to get that passion back.”
Sten: “I always feel people should follow their passion. I firmly believe that people will always be the best, the most successful at something they love. Of course, it is a job and it pays your bills, but it’s also going to be something you are going to do for gazillions hours in your life, so better pick something you like doing.”

Pampers reacted to Puddy for an article, Dynamic levels - in Payday 2 and beyond
Payday 2 is a cooperative first person shooter where players band together to commit various crimes in the endless pursuit of wealth, infamy and cool masks to cover their criminal faces with. The game recently celebrated it’s third birthday, yet it still retains a steady player base. How then has the game kept players engaged throughout the years? The many and regular content updates are surely a big part of it. Another draw must be the fleshed out progression systems that offer tons of customization. I would argue that the lifeblood of the game is its dynamic level design; it is what keeps the game replayable and fun. In this article I will discuss what dynamic level design is and how it was used to build “Hoxton Breakout”, one of the game’s most popular missions.
Payday 2, Left 4 Dead 2 and even XCOM2 all use some form of dynamic level design.
What is dynamic level design?
Dynamic level design is all about creating levels that are as replayable as possible; it is about retaining the challenge and keeping players on their toes. This is achieved by introducing elements that change between playthroughs, things that make the level a bit different each time you play. Dynamic levels are still designed and built by hand, so to speak, which makes them different from procedural levels which are created from automated algorithms.
Dynamic levels are useful in games where the developer wants the levels to provide more gameplay than a single playthrough would. This approach has the added benefit of allowing different players to come together and enjoy the same level, irrespective of whether they have played it many times before or not at all. This can make dynamic level design ideal for co-op games and it can be essential for retaining players over longer periods of time, just like Payday 2 has done.
Building a dynamic level
The process of building a dynamic level certainly differs from more traditional single player level design. Instead of crafting a linear experience in meticulous detail, a designer must seek to create a broader structure of what will happen in the level and then design dynamic elements, things that change between playthroughs, within that structure. These dynamic elements need to be designed with care, so that the level actually changes in meaningful ways between playthroughs. The process of making a dynamic level will vary from game to game; it all depends on the game's mechanics, setting and other details. By sharing the design of a Payday 2 level I hope to illustrate what a dynamic level can look like and also showcase the overall possibilities of dynamic level design.
Hoxton in all his glory, featured here in this promotional art. Shortly after his breakout, he leads a daring break-in at the FBI to uncover who ratted him out.
In the Payday 2 mission “Hoxton Breakout” players are tasked with breaking their old heisting comrade Hoxton out of custody. During the breakout Hoxton shares his suspicion that his capture was caused by an unknown snitch. To uncover the truth, the PAYDAY gang set their sights on the headquarters of the Federal Bureau of Intervention (not to be confused with any real life organization...). This sets the stage for the mission’s second level and the one I will be discussing here.
In this level, the players will enter the FBI headquarters together with Hoxton (an NPC). They will fight their way to the “Operations Room”; the place where the FBI servers are kept and where the Payday gang is hoping to find the information which reveals the identity of the snitch. Hoxton will search through the servers and when he has found what they need, the gang will escape. No matter how many times you play the level, the overall structure will stay the same. Instead, it’s the dynamic elements within this structure that change and make it replayable. What are those, you ask? Let’s take a look!
Clockwise from top right: The FBI HQ lobby, a central area in the level. The FBI director hides behind his desk. Hoxton and the Payday gang enter the lobby.
The Operations Room
Players will spend a lot of time in the FBI Operations Room. Hoxton will be hard at work searching through the servers, leaving players to defend him from relentless police assaults. The combat space will change in a number of ways between playthroughs.
Entrances - Most of the entrances to the Operations room are selected dynamically in various combinations, which changes which choke points the player must defend.
Windows - The ‘Operations’ room is two floors in height and the second-floor windows overlooking the room are placed in different positions. Players must watch them for enemy fire.
Fuse box - The fuse box, which enemies use to cut the power to the servers and pause your progress, can be placed in a few different positions. Players must defend it.
Ceiling breaches - SWAT troops can breach the ceiling of the ‘Operations’ room and rappel down right into the thick of it! There are a few places where this can happen (it doesn't always).
These dynamic elements will vary and change independently. This can be very desirable, as it will give you a large set of different combinations and improve the replayability of the level. For example, even if the fuse box is in the same location in two separate playthroughs, the positioning of the entrances and windows will change how the players approach the situation, which will help reduce level fatigue.
The Operations Room. The Servers are kept in the room under the illuminated FBI logo.
There are four servers Hoxton must search through in the Operations Room. Between the searching of each server, Hoxton will need the player's assistance and send them on a “quest”. There are five different quests, though only three are selected and used in each playthrough. They can be selected in any order and combination. Each quest and its gameplay have been designed to have a slightly different flavor.
Security Office - The next server happens to be heavily encrypted. You need to break into the Security Office, download the encryption keys and get them back to Hoxton.
IT Department - The next server is missing and the log states it was taken to the IT Department for maintenance. You must locate the IT Department, find the missing server and bring it back to Hoxton.
Archives - Hoxton finds a reference to some physical files kept in the archives. You need to go down to the basement, search through the archives and bring the paper files to Hoxton.
Forensics - Hoxton learns that the FBI has evidence related to the traitor. Players need to break into the evidence locker, find the right piece of evidence and then scan it in the nearby laboratory for clues before returning to Hoxton.
Director’s Office - Hoxton encounters some files on the next server that can only be accessed by gaining direct approval from the FBI Director. You must head to the director’s office and use his computer to approve all of Hoxton’s security clearance requests.
What this means is that players won’t know exactly which “quests” they will tackle each time they play the mission, or in which order they will face them. As the difficulty slowly ramps up during the mission and the players’ supplies generally are lower towards the end, completing the same quest as either your first or last one can become quite a different experience, even though the quest itself doesn’t change that much. Allowing the quests to be arranged in any order and combination simply gives the mission a slightly different flow each time.
The five quests, clockwise from top right: IT Department, Security Office, Archives, Forensics. Center: Director's Office
The Combat Now, it’s about time we talked about the combat. It is essential for the replayability of a level that the combat isn’t static and that encounters vary between playthroughs. To solve this, Payday 2 has a spawning system that serves up dynamic enemy encounters. The system unburdens individual level designers and creates a consistent and tweakable way for the game to spawn enemies in all levels. For those of you who have played the Left 4 Dead games this may sound very familiar. The system isn’t completely automated and the level designer can control a few variables.
Difficulty - The player selects the overall difficulty of a level before starting, but a designer can tweak the difficulty to a factor between 0 and 1. This can be adjusted at any point during the mission and can be tied to certain events.
Spawn locations - A designer designates spawn locations manually. The designer can toggle spawn locations on and off, change how often they can be used to spawn enemies and which kind of enemies are allowed to spawn from them.
Enemy Wave Mode - Police assaults occur regularly and this is generally handled by the system, but a designer can force a police assault or a complete break from them.
Snipers/Harassers - The placement of snipers and so called harassers, regular SWAT troops who harass players from vantage points, is done manually. It is up to the designer to place them in challenging, but fair, positions and script logic which decides when and if they appear.
What this all means is that while the spawning system does the heavy lifting and creates varied combat encounters, a designer can fine-tune the experience and still direct the combat somewhat. For example, in Hoxton Breakout the difficulty is slowly ramped up after each completed server, the spawn locations are continuously tweaked throughout the mission to make fights fair and when it is time to escape an endless police assault is forcefully triggered to increase the stakes!
A dynamically spawned enemy squad moves towards the Payday gang.
The keycard economy
In Payday 2, keycards are single-use items that are occasionally used to open certain doors. In order to add depth and strategy to the level, I added something to this level which I like to call “the keycard economy”. In every playthrough, players can find 3-4 keycards which can be used, i.e. “spent”, on a variety of options like overriding doors to seal them off from enemies, unlocking rooms that contain precious resources or opening doors that lead to objectives. The value of the different options can change between playthroughs, depending on dynamic variables and which loadouts the players have. Since players can’t have all the options, they must choose wisely. This allows players to refine their strategy over the course of multiple playthroughs, adding to the level’s replayability.
The little things We’ve discussed all the major dynamic elements of the level at this point, but it is worth mentioning that replayability also arises from smaller dynamic elements too. These smaller surprises can throw players off and force them to adapt accordingly. A good example can be found in the Security Office, where the police sometimes pumps in tear gas when players are trying to complete the objective inside. This forces players to leave the relative safety of the room and charge head first into the police forces which are surely waiting outside. Part of making a dynamic level should be to identify and implement these little game changers!
Clockwise from top right: The Security Room fills with gas. A keycard has been used to seal a security door. An innocent keycard. A SWAT team rushing to thwart the payday gang.
To summarize, the level we’ve looked at is about defending a location and completing short “quests”, with both activities changing in different ways between playthroughs. In addition to this variety, enemies are dynamically spawned, occasional surprises appear and players are able to learn and master the keycard economy over the course of multiple playthroughs. These dynamic elements, this variety between playthroughs, is what turns the level into a dynamic one.
This level was made for Payday 2 and, as mentioned, dynamic levels will look a bit different depending on the game and its needs. The Left 4 Dead games have less emphasis on objectives and focus more on linear progression through a level, with dynamic enemies, items and minor path changes along the way. The Killing Floor games have arena levels that suit the game’s wave-based horde mode and these levels feature fairly simple dynamic elements: enemy and item spawning as well as the location of the weapon and item shop. The revived XCOM franchise uses levels which have designated areas or “slots” where different buildings and structures can fit in and shift the layout accordingly. The XCOM games also allow different missions to be played on the same level, enabling levels to provide even more gameplay mileage.
The dynamic level design approach may fit these games, and others like them, but it is not suitable for all kinds of games and it definitely comes at a price. Since dynamic levels are designed to be replayable, heavily scripted story moments and set pieces may have to be deemphasized or removed outright. Playing through such sections may be thrilling once or twice, but they generally lose their appeal very quickly. Furthermore, some degree of polish is generally lost in the process of making dynamic levels. The fact that you are making an experience that can’t just happen “in one way” means you can’t necessarily polish, and control, every moment of gameplay to an insane standard, like you would expect in an Uncharted game for example. Additionally, an incredibly strong core gameplay loop is almost a requirement for a game with dynamic level design. Since the levels can’t be overly scripted, directed and set-piece heavy, the levels can’t compensate and “lift up” a slightly weaker core gameplay. Finally, one must also consider that creating dynamic elements in a level takes time, time which could be spent polishing or making more non-dynamic levels.
These drawbacks must be weighed against the potential benefits. After all, the value of replayability should not be underestimated. As I mentioned in the beginning of the article, dynamic levels seem to be almost ideal for co-op games. Playing games together definitely adds something to the experience and this can help to compensate for some of the potential drawbacks like the lack of set-pieces. Adversarial multiplayer games, i.e. player vs player, don’t necessarily stand much to gain with the dynamic level design approach as the element of human unpredictability and challenge is usually enough to keep players engaged and entertained. By looking at XCOM, we can see that dynamic levels can be used to great effect in a game that isn't a shooter nor a cooperative one. And if we compare them to procedural levels, dynamic levels requires less sophisticated technology to create, but more human labor, and can offer something that feels a bit more handcrafted and unique. Ultimately, game makers need to look at the dynamic level design approach, its pros and cons, and ask themselves: is it the right approach for us?
Pampers reacted to will2k for an article, Optimizing An Open Map in Source Engine
An open map?
Source engine, which is funnily a Quake engine on steroids (a bit of exaggeration but still), inherited the same limitations of its parents in terms of visibility calculations: BSP and PVS. This fact makes Source, as was Quake engine before, more suitable to rooms and hallways separated by portals where the BSP shines in all its glory.
Inheritably, Source does not like large open maps where the PVS is of considerable size and the over-rendering is a real issue.
If you work with Source engine, then you already know the importance of optimization in a large, detailed map. Optimization becomes even more imperative when the said map is open.
What’s an open map? Good question. The word “open” is an umbrella term to denote any map that does not have traditional hallways and corridors that connect indoors to outdoors. The map is mostly large, outdoors with an unbroken skyline; in other words, the same stuff that source engine nightmares are made of in terms of PVS and BSP.
In a traditional “hallway’d” map with twisted corridors leading to open areas followed by other hallways, and even if you “forgot” to place hints and areaportals, the geometry itself allows the engine to cut visleaves and limit visibility; granted the visleaves’ cuts will be subpar and messy and the PVS will be in excess, but still, the visibility and fps will be relatively under control. A twisted hallway is a remedy to long sight lines after all.
In an open map, and without hallways and enough geometry to help the engine, the PVS risks to be huge and the whole map could be rendered at once from any point (over-rendering). We are talking here about a severe fps killer and a potential slideshow on a medium to low range computer. Source does not like over-rendering; I repeat, Source does not like over-rendering.
I believe a screenshot should be welcome at this stage to illustrate an open map. I’ve chosen a nice medium-size map from CSGO to showcase the issue: de_stmarc.
The shot is taken in Hammer obviously, and you can immediately see that the skybox is one big unbroken body from one edge of the map to the opposite one. This is the classic definition of open map.
Let’s see this map in 2D view from the side.
I have highlighted the skybox in blue so you could see the continuous sky body all over the map. Please note that an open map can have varying skybox shapes but I’ve chosen the simple and classic one to showcase my point where it is easier to see and visualize the concept of open map.
In contrast, a “traditional” map will have several skyboxes, often not connected directly but rather through a system of indoor rooms or hallways, varying in size and shape.
I will have my map de_forlorn as example here.
I have also highlighted the skybox in blue and you can easily notice several skyboxes for CT spawn, T spawn, and Mid/bombsites. These skyboxes are not directly connected to each other but the areas related to them are linked on the lower levels through various indoor locations, some vast (like garage, tunnels…) and some small (like lab hallway…).
If you are not that comfortable with source optimization or feel that certain terms are alien to you, then please read my previous optimization papers and articles before proceeding further in this article (Previous papers can be found here Source Engine Optimization roadmap).
The necessary tools
I’m not revealing a secret when I tell you that the same tools used to optimize any map in Source are exactly the same ones used for optimizing an open map. If you were expecting some magical additional tools, I’m sorry to bust your bubble.
Since the tools are the same (nodraw, func_detail, props, hints, areaportals, occluders…), it is more about how to use them in open maps that makes all the difference.
So, how to properly optimize an open map? Well, you could always pay me to do so for you (joking…not…maybe…I dunno!!)
If the above option is off the table, then read on the rest of this article .
While in a traditional map one might get away without using horizontal hints, it is virtually impossible to skip them (pun intended) in an open map unless you want to witness single digit fps burning your eyes on the screen. They are of utmost importance to negate the "tall visleaves across the map" issue.
In a traditional map, even if you bypass adding horizontal hints, the damage in fps will mostly be local since the skyboxes are not connected and areas are mostly autonomous in terms of PVS. In case of my map “Forlorn” and referring to the 2D diagram above, if I remove horizontal hints from CT spawn, then only this area will suffer from tall visleaves and over-rendering. Obviously, this is not cool in terms of optimization, but at least the effect will be somehow restricted to this area only.
In the case of “Stmarc”, you can certainly see that not including horizontal hints will have tall visleaves seen from across the map as the skybox is one unit. The PVS will grow exponentially and the over-rendering will take its toll on the engine.
Let’s move on to some screenshots and diagrams, shall we.
This is our glorious open map in side view. The blue lines denote the skybox, the dark grey one is the ground, and the green rectangles represent solid regular world brushes such as building bases for example. The red starfish little-man-with-arms-wide-open is the player. The orange hollow rectangles denote the various visleaves that the engine would probably create in the map (most go from ground level to skybox level and this is what I refer to as “tall visleaf”).
If you know your optimization, then you certainly remember that BSP relies on “visibility from a region” approach (for a refresher, please consult my papers Demystifying Source Engine Visleaves and Source Engine PVS - A Closer Look. This simply translates to the following: the player is in visleaf A and visleaf A has direct line of sight to visleaves B, C, D, E, F, and G. The PVS for A in this case would be stored as BCDEFG. Once the engine recognizes that the player is in A, and regardless of the exact position in A, it will proceed to render the whole PVS content. Everything in visleaves BCDEFG will be rendered even though the player is at the extreme end of A and has no line of sight to most of this content.
You can immediately notice the extent of damage you will inflict on your open map if you neglect adding horizontal hints: excess PVS with additional useless content to be rendered at all times.
Now that we established the importance of these horizontal hints in open maps, the question remains: where shall I put these hints?
In the diagram above, the most logical places would be on top of the 3 green rectangles.
We added 3 horizontal hints (H1, H2, H3) on top of the 3 regular brushes in our map (the hint face neatly resting on the top of the regular brush while other faces are textured with “skip”). This will create more visleaves as can be clearly seen in the above diagram, and vvis will take more time to calculate visibility due to the increased number of leaves and portals but this is done for the greater good of humanity your map’s fps.
Now the player is in visleaf A1 and the PVS is reduced to (sit tight in your chair) A2, A3, A4, B1, B2, C3, C4, D1, E4, F3. On top of the nice result of a greatly reduced PVS (and therefore content to render), keep in mind that leaves A4, B2, C4, D1, E4, and F3 are mostly empty since they are way up touching the skybox.
Some folks will start complaining and whining: what the hell dude, I don’t have 3 green rectangles in my map; where would I put my hints?? My answer would be: deal with it!!
Joking aside, open maps will greatly differ in size, shape, geometry, and layout. What you need to do is choose 1 to 5 common height locations in your map where you would implement these hints. Medium maps with mostly uniform building heights can get away with 1 horizontal hint, while complex, large maps with various building heights can do with 4-5 hints.
If your map has a hill made of displacements that separates 2 parts of the map, then it is also a candidate for horizontal hints. You just need to insert a nodraw regular world brush inside the displacement to be used as support for the horizontal hint (the same technique can be used if you have a big non-enterable hollow building made mostly of func_detail/props/displacements).
These might not come into play as much as their horizontal siblings, however they could see a growing potential use depending on the map’s layout, geometry tightness versus openness.
I cannot go through all combinations of open maps obviously to show you how to lay vertical and corner hints; what I will do is choose one diagram representing a typical open map scenario with some scattered houses, streets, and surrounding fields. Once you see how I proceed with these hints, it will become a lot easier for you to implement them in your own map regardless of the differing geometry and layout.
Here’s our typical map viewed from top with grey lines being map borders, green rectangles being houses (solid world brushes), and our tiny red player at the rightmost part of the map. The map has a main street that goes in the middle between houses but the player is not restricted to this path only.
The diagram below shows how I would proceed with my hints for such setup.
This is basically what you get when you give a 5-year-old some crayons.
Seriously though, I just gave each hint a different color so you could discern them on the spot, otherwise it would be hard to tell where each one starts and ends.
Most of these hints go from one side of the map to the other while going from ground level to skybox top; don’t be afraid of having big hints that cross your entire map.
Notice that we have both straight vertical hints (shown from above in the diagram obviously) and corner hints; what I did is that I compartmentalized the map so wherever the player is, chances are they will have the least amount of leaves to render in the PVS (this is just a basic hint system and more fine tuning and additions could be done but you get the gist of it).
To get more details on hint placement, please refer to my paper Hints about Hints - Practical guide on hint brushes placement
If your map has enterable buildings, then it is imperative to separate indoors from outdoors using areaportals; this is top priority.
Make sure to slap an areaportal on each door, doorway, cellar door, window, roof opening, chimney, etc. that leads inside the house in question.
What about outdoor areaportals? Good call. In an open map without much regular world brushes to maneuver, it could get very tricky to set up an outdoor areaportal system to separate areas. However, you should always strive to have one, even if it is one or two areaportals across the map. The reason is very simple: the view frustum culling effect, which, coupled with hints, will yield the best results in cutting visibility around the map.
Continuing with our previous diagram, a simple outdoor areaportal system setup could be as follows (top view).
This setup will make sure that the map is split into 4 areas and whenever you are in one of them as player, the view frustum culling effect will kick in to cull as much detail as possible from the other areas.
Let me show you the setup from a side view to make it easier to visualize.
This is the same areaportal that was closest to the player in the top down view diagram but this time viewed from the side. Unlike hints where it’s fine to have one big hint going across the map, for areaportals, it is best to have several smaller ones that tightly follow the contour of the geometry eventually forming one big areaportal system.
Another possibility for outdoor areaportal system is to have a combination of vertical and horizontal (yes horizontal) areaportals.
If your map is a village for example with a highly detailed central square where most of the action takes place, a potential system could be made of several vertical areaportals that sit in every entrance to the square from adjacent streets, and a horizontal areaportal that “seals” the area and works as a “roof”.
For a practical guide on areaportals placement, please check out my article Practical guide on areaportals placement
Props fade distance
This is a really, really important tool when optimizing large open maps. In case you got distracted while I was making the announcement, I’ll go again: props fading is definitely vital when tackling open maps optimization.
What you need to do is to set an aggressive fade distance for all trivial props that do not contribute to gameplay. Players will look closely at how detailed your map is when they check it out solo on the first run; however, when the action starts and the round is underway, adrenaline, focus, and tunnel vision kick in, and all the details become a blur.
During an intense firefight, players will not notice small props and details up close, let alone at a distance. We need to use this to our advantage to fade props thus releasing engine overhead; a faded prop is not rendered anymore and engine resources will be freed and allocated elsewhere.
Your map geometry will dictate the proper fade distances, but as a rough guideline, small props could have a fade distance anywhere from 800 to 1200 units (flower pot on a window sill, small bucket at the back door, a bottle on the sidewalk…), while medium props could do with 1400-1800 range (a shrub, a power box on the wall, an antenna on the roof, wood plank, gutter pipe, fire hydrant…).
Be very careful though not to prematurely fade critical props used for cover or game tactics (car in the middle of the street, sandbags, stack of crates, dumpster on the sidewalk…).
Many people forget about this technique which is more than needed when it comes to open maps that tend to have larger average PVS than traditional maps.
I showcased in a previous article of mine the fps cost of cheap and expensive assets (Source FPS Cost of Cheap and Expensive Assets).
Get in the habit of using the low-poly model version as well as the cheap texture version in the distant non-playable areas and the high unreachable areas where players won’t have much of close contact with the environment. Potential candidates could include a distant field, the unreachable opposite bank of a river, a garden behind hedges/walls, high rooftops, the 3D sky…).
Fog/Far-z clip plane
This technique, when correctly used, can provide a big boost to your frame rate as parts of the world beyond the opaque fog won’t be rendered at all.
For this technique to work properly, your map should have a foggy/rainy/stormy/dusty/hazy/night setting (use as applicable) where a fully opaque fog won’t appear out of place. Obviously, if your map takes place in a sunny and clear day, this technique won’t work much and it will look inappropriate.
Using this is simple: For example, if your map is set in a rainy and foggy day, you just need to set the fog end distance while having its density set to 1. You will then set the far-z clip plane to something slightly higher than the maximum fog distance (if the fog end distance is 8000 units for example, the far-z could be set to 8200).
This is another good technique to reduce engine overhead and the cost of rendering.
It is true that the 3D sky is used to expand the limits of your level and decorate its surrounding, however, since it is built at 1/16 scale (and expanded in-game), it is also a nice way to decrease rendering costs. Use this to your own advantage and relocate assets in the non-playable areas with limited player interaction to the 3D sky.
One thing to keep in mind though, the 3D sky’s visleaf is rendered at all times on top of the PVS in the playable area. Do not go overboard and make an extra complex, highly expensive 3D sky or you would be defeating the purpose of this optimization technique.
You thought I forgot about occluders? Not a chance as these are the big guns when it comes to large open maps with little world brushes to use for other optimization techniques.
Let’s clear one thing first; if your map is made mostly of brushwork and displacements with little to no props, then there is absolutely no need to resort to occluders as they’d be totally useless in this case. Only when the map is loaded with models and props in an open setup with little regular world brushes that occluders come to play in force.
To place occluders, you would search for areas where these occluders could make the most impact (low fps, high traffic, props abundance) since they run in real time and are expensive, otherwise their cost would outweigh their benefit in terms of frame rate variation.
Remember that occluders rely on the player’s position and field of view relative to the occluder to calculate what gets culled. You need to place them in a way to maximize the number of props to be culled behind them when the player stands in front of these occluders.
Let’s see some examples.
We go back to our famous top down diagram; the occluder is dark blue placed on the left wall of the large house while the little black stars represent various props and models. The 2 diagonal black lines denote the player’s FOV relative to the occluder. Anything behind the occluder and within the view frustum will be culled.
That’s nice; we are able to cull 4 props but is it enough? It is not optimal as we can still do better. What if we move the occluder to the right wall of the house?
Much better if you ask me. 5 additional props were added to the culling process meaning less overhead and fewer resources to render for the engine. That is why I said earlier it is all about maximizing the impact of the occluder by placing it in a way relative to the player’s position that maximizes the number of culled models.
Here’s another example (still top down view).
The player has moved to the middle of the central street, and beyond that L-shaped house is an open field with a lot of props scattered around. One way to implement occluders is as showcased in the above diagram. Notice how I arranged 2 perpendicular occluders along the walls for the maximum occlusion effect as all of these props in the field are not rendered from that player location.
Another way to arrange occluders in this case would be diagonally across the L-shaped house (split into 2 or 3 occluders if needed to accommodate the nearby geometry; they can be floating without the need to seal an area).
If you’re feeling brave enough (you should be after reaching this far in this article), you could also add an extra occluder along the wall of the house to the left of the L-shaped house to further enhance the view frustum occlusion effect and cover more props in the field.
The most common places to add occluders in open maps include a displacement hill that separates parts of the map, a hedge that stands between a street and a field full of props, a floating wall between a house garden and the street, the walls of a large house, the walls of a tall building, a ceiling when it separates multiple levels…
To read more about occluders placement and cost, please consult my article Practical guide on occluders placement
The foundation of optimization in Source engine will be the same whether it is a traditional map or an open one. You will heavily rely on func_detail, nodraw, displacement, props… to achieve your goals but it is the way you use these tools in an open map that makes all the difference.
One might get away with being a bit sloppy with optimization in a traditional map, however, make no mistake that an open map won’t be any forgiving if you decide to skip a beat in your optimization system.
Talking about different open maps and formulating varying optimization systems for them could fill articles; I hope this article has shed enough light on the open maps optimization approach to let you easily design a system for your own map.
Pampers reacted to Alf-Life for an article, Creative Airlocking: streaming in action games
Creative Airlocking: streaming in action games
This article will discuss the loading and unloading of areas in linear single-player action titles, and look at contemporary examples of how the best games mask these so they appear seamless.
When designing levels, Level Designers and Environment Artists must consider that their assets all have to fit within memory at once. While older action games like Wolfenstein 3-D and Doom would load the entire level with a Loading Screen at the start of each map, games like Half-Life started a trend of loading smaller sections gradually so they could squeeze in more detail and also provide a more seamless experience for players, making the game feel like one long adventure.
At the time, going from one space to the next in Half-Life resulted in a seconds-long hitch with the word “Loading” on screen. There was no warning that it was going to happen, although Valve’s Level Designers oftenplaced these level transitions in smart places; usually down-time between combat and in a natural chokepoint. In later years, with faster computers, these load times decreased and are now almost seamless.
Half-Life displays a small loading message when transitioning between levels.
Currently, blockbuster series like Gears of War and Uncharted provide truly seamless transitions. After one long initial load for a new chapter with a completely new location (with new art) – sometimes masked behind a pre-rendered movie – “buffer” Streaming Sections are used, in which the previous area is unloaded, and the next loaded, on the fly. Since a lot of the globally-used entities are already loaded, and the environment is usually the same, assets can be shared, which can reduce these transition load times to much less than the initial level load.
Essentially, these games take the smaller loading bar/screen of a more continuously-laid-out game like Half-Life, Portal 2 or Fallout 4 and make the player spend that time in the game world. If done creatively, players won’t even notice it. They might even enjoy the down-time if it’s well-paced, like The Last of Us where it can be spent on a thought-provoking puzzle or with the characters discussing something interesting.
Most action games budget out large areas, and then connect those with these smaller Streaming Sections.
Section (A) is a huge space with lots of combat, Section (C) is another. Players in Streaming Section (B) can’t see into both (A) and (C) at once. Section (B) is where Section (A) is dropped from memory and (C) starts to load in. Section (A) being dropped shouldn’t happen in view of the player, and unless the game supports backtracking it is wise to place a back-gate to stop players returning, for maximum efficiency. As soon as Section (A) has been dropped, Section (C) can start loading in. It must have been loaded by the time the player exits Section (B), so it is also wise to front-gate players in case they rush through.
The best way to think of a Streaming Section is as an airlock; the “door” behind the player is locked, the next area is loaded, and the “door” ahead opens. Ideally, these sections aren’t literal airlocks but instead nicely-disguised puzzles or narrative spaces between the action.
Back-gating, and Unloading
Back-gating, as the term suggests, is when the player is prevented from returning to a previous area. The ‘gate’ behind them is closed, in a lot of cases locked. This doesn’t have to be a literal gate or door, though. A ceiling can collapse causing debris to block the path behind the player, the player can fall through the floor and not be able to climb back up, they can pass through a one-way portal and not get back.
Back-gating after entering the Streaming Section is usually done around a corner where the player can’t see Section (A) being unloaded.
One-way animations are the main manifestation of these in modern action titles. Think of how many doorways your player character has held open, only to have it collapse behind them. The level section behind that door is now being unloaded, to make space in memory for the next large section. In co-op games, these animated interactions are a great way to bring players back together so that Player 2 isn’t left behind, only to fall through the world, in the section that is just about to be unloaded!
The Last of Us has a huge variety of bespoke, painstakingly-animated back-gates.
A cut-scene can also serve as a good back-gate, as long as it makes sense in the context and/or story so as to not feel tacked on, and is within development budget!
One-way drop-downs are also a great and less flow-breaking back-gate. If the L-shaped area just before the drop-down can be kept in memory, as soon as the player drops down a ledge they can never climb back up, the previous area can be unloaded. The only down-sides to this softer back-gate are that they can feel contrived unless the game’s art and world can support it (terrain and collapsed structures are great for this), and that co-op players may have to be teleported to the dropping player so that they don’t fall through the world when Section (A) is unloaded.
Slowing the player down, and Loading
As Streaming Sections are usually connectors between two larger areas, they naturally make for slower-paced breaks in the action. Since Section (C) is being loaded in, slowing the player down in (B) – either literally as with Gears of War’s infamous forced walks or cerebrally with light puzzle gameplay – can be more efficient and interesting than just making a large footprint which has to cater for a player, say, sprinting for 30 seconds.
Even when rushed, this plank puzzle in The Last of Us takes time and offers a nice respite.
“Popcorn” encounters with just 1-2 enemies can be a good trick to allow loading to finish and slow players down and prevent them from simply rushing through a short Streaming Section. They also keep players on their toes and vary the flow from, for example, combat to puzzle to combat.
Interactive Objects such as the slow-turning valves in Killzone 2 and the Gears of War games can also buy some loading time, as can environmental obstacles such as jumps or mantles or animations where the player’s buddy looks around for, and then finds, a ladder to kick down for the player to climb (also a good front-gate).
Interactions like the valve in Gears of War slows players down and can also act as a front-gate.
These approaches can also be combined in ways that fit the feel of the game, such as a Grub locking the player in a room and flooding it with frightening enemies in the first Gears of War game.
Batman Arkham Asylum does a great job with additional ‘softer’ methods of slowing players down by playing a captivating well-acted taunt on a monitor from The Joker, or by encouraging exploration with The Riddler’s location-specific riddles or any number of collectibles.
Front-gating, and Loaded
As with Back-gates, front-gates are quite self-explanatory – the exit to the area the player is currently in is locked until certain conditions, such as all the enemies in the room being dead or the next area having loaded in, are met. Again, this doesn’t have to be a literal gate or door, just an obstacle in the world that can change its state from closed and locked to open.
A lot of games from the Call of Duty series to Killzone 2 to The Last of Us extensively use friendly characters to unblock a front-gate; chain-link fences are cut through, doors are kicked open, wooden beams are lifted. New waves of enemies can also open a front-gate for the player and offer the bonus in that noisy, gun-firing AI attract players, like carrots on a stick, to the newly-opened exit. Many action games have excellent examples of enemies blow-torching open a door to get in or a huge monster bursting in through a wall; not only are these cool enemy entrances, but oftentimes their new unorthodox entrance-ways become cool exits, sign-posted by their un-gating event.
Previously-locked doors in Halo often flash and make noise when opened by new enemies.
Not all games front-gate the exits of their Streaming Sections because the time needed to load a Section (C) can usually be accurately gauged, and the acceptable fallback is a slight hitch. However, front-gates do provide that extra failsafe to ensure the next area is loaded before leaving a Streaming Section – in this case, a player with a scratched disk or corrupted file could see out of the world, at best, or get stuck or fall out of the world, at worst (though it could be argued someone with a scratch or corrupted files might see worse issues regardless).
The biggest issue here is that front-gates need to fit the game or the level art – neat doorways or bottlenecks aren’t always possible. The other big issue is repetition; if a specific door interaction animation is always used, the game needs to provide a lot of variety in that animation!
One trick that can be used to alleviate repetition, however, is if the front-gate is out of sight near the end of the Streaming Section (A). A check can be done to see if Section (C) has loaded, and if it has, the door can potentially be pre-opened saving the player another potentially-repetitive interaction but also holding as a true front-gate if a player does rush through.
Batman Arkham Asylum had an interesting front-gate in the penitentiary sections; a security camera scanned Batman once before opening the door. Given the backtracking-heavy structure of the game, when racing through at full pelt, if the next area had not finished loading, the camera would loop the camera’s scanning animation. This is a great compromise because the camera scan completely fits the fiction of the world, and an extra scan animation would probably go unnoticed by many players.
Batman Arkham Asylum’s Penitentiary’s doors only open when loading is complete.
In most linear action games, keeping the player immersed in the world is preferable to seeing a loading screen. If developers can create interesting activities, take advantage of slower pacing through narrative, or just make smart use of assets and an interesting space to traverse, Streaming Sections can be part of the world and not feel like generic winding corridors that stand out even to uninitiated players as padding.

Pampers reacted to PeteEllis for an article, Creating a Single-Player Combat Space
This article is the first installment in a three-part article that looks at the considerations for creating a single-player combat space, using a walkthrough of the first battle in ‘Killzone Mercenary’ as a working example.
Creating a Single-Player Combat Space Part 1
This article will explain how to create a combat space for a single-player campaign, using my work on ‘Killzone Mercenary’ (hereon referred to as KZM) as an example. There is already a fair amount of literature on the different methods you can use for creating a combat encounter, but I felt that none of it really discussed how to arrange the layout in closer detail, nor did they discuss where the different elements were appropriate. In my early work I tried to jam in all the concepts for encounter design without fully understanding how they affected the player’s experience. As strange as it sounds, I discovered there were times when it was better to restrict the number of elements being used to provide a much more focused and coherent experience; sometimes less is more. I will take you through an example to explain what I mean and how this can be the case.
I will use the very first combat arena in KZM as it’s a small encounter where I can explain in depth what goes into even the most basic combat space. This encounter is a fight against assault troopers who are trying to stop the player from escaping the building and reaching the objective building; the ‘Halls of Justice’. I designed bigger encounters that featured many flanking opportunities and complex circular navigability but focusing on a simple encounter allows me to explain certain techniques in detail and where I purposely removed some elements to balance the difficulty and give the player different experiences.
First of all I will explain two important aspects that must be considered for combat creation; AI metrics and weapon choice. I will then take you through a step by step walkthrough of this first encounter explaining in detail the reasons how it was designed and constructed for optimum player experience.
The design mantra ‘form follows function’ should be the basis when creating an arena layout; that is that the arrangement of geometry should derive from its purpose. The arrangement should support the function not only of the style of experience you want to create (is it a tight corridor section with close quarters combat or an open space with multiple routes and options, for example) but it should also support the main element that makes up the combat encounter; the enemy AI.
When considering the layout for the AI or non-player characters (NPCs) that will populate your environment you have to consider their metrics. These are the numerical values for how the NPCs move around and use the environment and the differences between various NPC enemy classes. This isn’t something people tend to talk about and so it can be easily forgotten or missed, yet it directly affects how your enemies will move and react.
For example, in KZM the standard enemy NPC class were the Assault Troopers. These soldiers could be given patrols and animations to perform whilst they were in an ‘unalerted’ state, just like every other enemy class. However, when they were in an alerted state their behavior changed so that they used cover points to move around the combat space. The maximum distance between cover points that an assault trooper would move was 10 meters. This meant that any cover point that was further away would not be considered, so we needed to make sure when creating combat spaces which used assault troopers that there were enough cover islands so they could move around. If there weren’t, the assault troopers would just stay in the same spot and could risk looking less intelligent.
The assault troopers also tried to maintain a distance of 15m whilst they were trading shots with the player. The behavior was that if the player got closer than this range, but not so close that they were in melee combat distance (5m), the assault troopers would retreat to this mid-range distance of 15m. They would also never choose a cover position that was closer than 15m to the player, so when we created combat spaces we had to make sure that there was enough variety of cover positions in the >15m range.
For the production of KZM we used the ‘Killzone 3’ engine and modified it for the PS Vita. In ‘Killzone 3’ the assault troopers picked their cover within a range that was further than 25m from the player, but we discovered that this was too great a distance for the enemy to still be clear and readable on the PS Vita screen. In our modified version of the KZ engine we had to reduce the combat distance to 15m, which meant that the original combat spaces we had created using the ‘Killzone 3’ metrics also needed adjusting in order for the NPCs to still work. It is an unfortunate truth that the game metrics, be it for the AI or otherwise, can change within a game’s development, which means that your combat arenas will also need to be adjusted.
The metrics for both the player and enemy weapons were also considered. As this is the start of the game we can be more certain that the player is using the default starting weapons, at least on their first playthrough, before they have earned enough credits to buy a new arsenal. Therefore, the combat distances of enemy placement were considered to be comfortably within range for the player’s assault rifle.
The enemy assault trooper archetype used assault rifles that were balanced to have a short range of <10m, and a long range of >20m. This meant that their behavior was to try and keep the player within these ranges and would thus move around the environment to try and maintain this. This was important to consider when building the environment so we could determine the amount of movement the troopers were likely to perform. This is important for balancing difficulty as a moving target is harder to hit.
As this was the opening of the game, we wanted to make it compelling in order to grasp and hold the player’s attention; we wanted to start with a bang. If the first lot of encounters in the game only included assault troopers with nothing else to differentiate them it may not have been so compelling. Therefore, we decided to include a significant Killzone enemy vehicle; the Helghast Dropship. Of course it would have been far too difficult to fight a Dropship at this point in the game, so instead it was used as an impressive introduction of enemies into the arena using the rappel ropes from the ship itself.
Using the Dropship at the end of the encounter, it was important to foreshadow its existence prior to its introduction. The level’s opening cut scene introduces the buddy character, Ivanov, and the narrative that he and the player are infiltrating the building whilst trying to avoid the searching eye of the Dropship.
The foreshadowing of the Helghast Dropship
Once the player has control they make their way up a flight of stairs learning how the movement works and feels whilst being in a safe environment. Once at the top of the stairs they enter through a door where they are introduced to the new melee attack which utilizes the touch screen on the PS Vita.
After a successful melee attack the player enters through the door to the first combat area. The composition shows the exit of the arena in the top left third of the frame. Central to the player’s view is where the first pair of enemies enter from, ensuring that their arrival is not missed.
The exit to the arena is in the top left section of the opening composition
Starting on the level above, the two assault troopers vault down into the gameplay space, to give their presence a more dramatic opening than merely walking in through a door. Their animation and movement also ensures that they catch the player’s eye if they aren’t looking in the desired direction. These vault down animations were 4m high, the standard height for a room in KZM, which meant this was a metric we had for the balcony and floor above.
Two assault troopers drop into the environment from the level above
Once the assault troopers had landed in the arena they became a lot less mobile than their standard behavior so that they were easier to shoot because, as previously mentioned, a moving target is harder to hit. As this is the very first section of combat the player encounters in the game it was important to ensure that it was easy to get to grips with.
None of the enemies were waypoint/navmesh restricted to certain areas in order to limit their movement as this could potentially lead to NPCs not behaving correctly under differing circumstances. In fact, there were only a very select few instances where we waypoint/navmesh restricted any characters in the whole of KZM; we instead crafted the environments to support the behavior we wanted from the NPCs. This was important for consistency; if you restrict areas and zones for the AI then they won’t behave consistently with what the player has learnt. This would lead to the player not being able to predict their behavior and therefore won’t be able to plan how to attack effectively.
Here, in this first section, the two assault troopers took cover at two upright pillars of high cover and an overturned sofa of low cover. They didn’t tend to venture further into the environment unless the player had for some reason retreated to the edges of the level. The reason they wouldn’t move and advance on, or flank the player was because the other cover options in front of them were within 15m of where the player was likely to be stood. This caused them to be more static and thus easier targets to allow the player to get to grips with the shooting mechanics.
I also chose to mainly use higher cover here so that when the enemies lean out of cover their shooting positions allowed the player to shoot their full body, which was a bigger target than when they poked their heads over the top of the low cover positions.
Low cover positions are great for seeing the enemies move around and change their positions, as the tops of their helmets are visible over the top of the cover. Enemies are much harder to track when they use high cover as it breaks line of sight to them, so this is usually the harder option. However, as they have restricted cover positions and weren’t moving around in this specific situation, it was the best option to use for less difficulty.
First Combat Front
A ‘front’ is the perceived line or boundary that faces the enemy and is the nearest position which combat should be engaged from. The ‘fronts’ used here create boundaries between the two sides; a front for the player and the buddy character and an opposing front for the two assault troopers. This was the simplest setup to start the player off with and it only required two sets of cover points as I didn’t want to encourage the enemy to flank the player at this stage. This section of the encounter only needed these few pieces of cover (in the image below) in order to work and the other pieces of cover were actually for further waves of combat.
The two fronts and the cover setups providing it
It’s also worth noting that the cover object which the buddy character crouches behind is positioned further forward than the arrangement of cover that the player is drawn to. This is so that the buddy character is in the player’s view so they always see the buddy’s actions and involvement. It wouldn’t be optimal to have a buddy NPC that the player rarely saw. The buddy is also kept near to the player in order to maintain a close relationship and the feeling of being a team. Empathy is directly related to proximity between characters, so if the buddy was further away from the player they would experience a much more detached feeling towards them.

It’s finally time to declare a grand prize winner in our exciting Counter-Strike: Global Offensive mapping contest. You’ve playtested the maps on Reddit, you've waited months for the results... let's get down to business!!
GRAND PRIZE WINNER:
By Andre Valera
Sometimes it boils down to consistency: broad strength across several categories. No map in our contest better exemplifies this notion of consistent quality than Empire.
Empire features a stacked bomb-site layout similar to popular official maps like Nuke and Overpass. While this relatively unorthodox design presents level designers with additional challenges, Empire ably sticks its landing. Furthermore, the ambition of Empire’s design is tempered well by its no-nonsense visual presentation. We’re left with a digestible, fun, and very playable level.
Congratulations, Andre Valera!

Pampers reacted to leplubodeslapin for an article, Source Lighting Technical Analysis: Part Two
This is the second part of a technical analysis about Source Lighting, if you haven’t read the first part yet, you can find it here.
Last time, we studied the lightmaps, how they are baked and how VRAD handles the light travel through space. We ended the part 1 with an explanation of what the Constant-Linear-Quadratic Falloff system is, with a website that allows you to play with these variables and see how lighting falloff reacts to them. We will now continue with basic examples of things you can do with these variables.
Examples of application
The simplest type of falloff is the 100% constant one. Whatever the distance is, the lighting has theoretically the same intensity. This is the kind of (non-)falloff used for the sun lighting, it is so far away from the map area, that light rays are supposed to be parallel and light keep its intensity. Constant falloff is also useful for fake lights, lights with a very low brightness but that are here to brighten up the area.
Another type of falloff is the 100% linear one. With this configuration, light seems to be a bit artificial: it loses its intensity but goes way further than the 100% quadratic falloff. It can be very useful on spots, the lighting is smooth and powerful. Here is an example:
This is the default configuration for any light entity in Hammer, following as we said before the classic Inverse-Square law (100% Quadratic Falloff). It is considered to be the most natural and realistic falloff configuration. The biggest issue is that it boosts the brightness so much on short distances, that you can easily obtain a big white spot. Here is an example, with a light distant of 16 units from a grey wall:
This can also happen with linear falloff but it is worse with quadratic. Simple solutions exist for that, the most common is not to use a light entity but a light_spot entity that is oriented to the opposite direction from the wall/ceiling the light is fixed to. You can make the opening angle of your light_spot wider, with the inner and outer angle parameters (by default the outer one is 45°, increase that to a value of 85° for example). If needed, you can also add a light with low brightness to light the ceiling/wall a bit.
50% & 0% FallOff
A second light falloff system exists, overriding the constant-linear-quadratic system if used. The concept is much simpler, you have to configure only 2 distances:
50 percent falloff distance: Distance at which light should fall off to 50% from its original intensity 0 percent fall off distance: Distance at which light should end. Well ... almost, it actually fall off to 1/256% from its original intensity, which is negligible. The good thing with this falloff system is that you can see the 2 spheres according to the 2 distances you have configured in Hammer. Just make sure to have this option activated:
An appropriate section for models lighting is needed, because it differs from brush lighting (but the falloff stays the same). In any current game engine, lightmaps can be used on models, a specific UV unwrap is even made specifically for lightmaps. But on Source Engine 1 (except for Team Fortress 2) you cannot use lightmaps on models.
The standard lighting method for models is named Per-Vertex Lighting. This time, light won’t be lighting faces but vertices, all of the model’s vertices. For each one of them, VRAD will compute a color and brightness to apply. Finally, Source Engine will make a gradient between the vertices, for each triangle. For example:
If we take a simple example of a sphere mesh with 2 different light entities next to it, we can see it working.
With this lighting method, models will therefore be integrated in the environment with an appropriate lighting. The good thing is that, if a part of the model is in a dark area, and another part is in a bright area, the situation will be handled properly. The only requirement for this is that the mesh must have a sufficient level of detail in it; if there is a big plane area without additional vertices on it, the lighting details could be insufficient.
Here is an example of a simple square mesh with few triangles on the left and a lot on the right. With the complex mesh, the lighting is better, but more expensive.
If you need a complex mesh for your lighting, you don’t want your model to be too expensive, you have to find a balance.
Two VRAD commands are needed to make the Per-Vertex Lighting work:
StaticPropLighting StaticPropPolys You have to add them here. You can find more information here.
Another system exists, that is much cheaper and simpler. Instead of focusing on the lighting of all the vertices, the engine will only deal with the model’s origin. The result obtained in-game will be displayed on the whole model, using only what has been computed at the model’s origin location. This can be an issue if the model is big or supposed to be present in an area with lots of contrast in lighting. The best example for that is at the beginning of Half-Life 2 with trains entering and exiting tunnels. We can see the issue: the model is illuminated at the beginning, but when it enters the tunnel it suddenly turns dark. And this moment is when the train’s origin gets in the shadow.
This cheap lighting method will replace the per-vertex lighting for 3 types of models:
For prop_dynamic or any kind of dynamic models used in the game (NPCs, weapon models in hand, any animated models...) For prop_physics For ANY MODEL USING A NORMAL MAP (vertex lighting causes issues with normal maps apparently), EVEN IF USED AS A PROP_STATIC
The big problem with these models is their integration in the map, they won’t show any shadow and their lighting will be very flat and boring (because it’s the same used for the whole model). But hopefully there are 2 good things with this cheap lighting method.
First, the orientation from which comes light is taken into account, if blue light comes from one direction, therefore all the faces oriented toward this direction will be colored in blue. And if you have different lighting colorations/intensities coming from different sides of your model, they should appear in game.
Here is an example of a train model using a normal map with 2 lights on both side. If you look closely, you’ll see some blue lighting on the left, on faces that are supposed to be in the shadow of the blue light but are oriented toward the blue light.
The second good thing is that there is still some kind of dynamic per-vertex lighting, but much simpler: it only works with light and light_spot entities (NOT with light_environment), and it just adds some light to the prop, it cannot cast any shadow (it only takes into account dynamically the distance between the light and the vertex). If we use again the high-poly plane mesh we had before as a prop_dynamic, being parented to a func_rotating that ... rotates. Light is dynamically lighting the vertices of the props. There is a limit of 3 dynamic lights per prop, it can’t handle more at the same time.
And if you add a normal-map in your model’s texture, this cheap dynamic lighting works on it:
Projected texture and Cascaded Shadows
Few words to finish the study with dynamic lighting. Projected textures is a technology that appeared with Half-Life 2: Episode Two in 2007, it consists of a point-entity projecting a texture in the chosen direction, with a chosen opening angle (fov). The texture is projected with emissive properties (it can only increase the brightness, not lowering it) and it can generate shadows or not. The great thing with this technology is that it’s fully dynamic, the env_projectedtexture can move and/or aim at moving targets. This technology is used for example on flashlights in Source games. But as usual, there is also a drawback: most of the time you can only use only 1 projected texture at a time, modders can change this value quite easily but on Valve games it is always locked on 1.
The cascaded shadows system is only used on CS:GO. The concept is quite similar from a projected texture but it doesn’t increase the brightness, it only adds finer shadows. It is used for environment lighting, using much smaller luxels than for the lightmaps and it is fully dynamic. It starts from the tools/toolsskybox textures of the map and cast shadows if it meets any obstacle. Shadows from the lightmap are most of the time low resolution and the transition between a bright and a dark area is blurry and wide. Therefore, the cascaded shadow will be able to draw a clear shadow around the one from the lightmaps.
When an object is too small to get a shadow in the lightmap, it will be visible thanks to the cascaded shadows. There are 3 levels of detail for cascaded shadows on Counter-Strike, you can configure the max distance at which the cascaded shadows will work in the env_cascade_light entity at the parameter Max Shadow Distance (by default it’s 400 units). The levels of detail will be distributed within this range, for example:
Since cascaded shadows and projected textures share some technology, you can’t use them both at the same time.
I really hope you have found this article interesting and learned at least few things from it. I believe most of these informations are not the easiest to find and it’s always good to know how your tools work, to understand their behavior. Source Engine 1 is old and its technologies might not be used anymore in the future, more powerful and credible technologies are released frequently but it’s always good to know your classics, right?
I would like to thank Thrik and ’RZL for supporting me to write this article, and long live the Core!

Pampers reacted to leplubodeslapin for an article, Source Lighting Technical Analysis: Part One
After the announcement of the Reddit + Mapcore mapping contest, the website has welcomed many newcomers. A proof that, even if it is a twelve year old game engine, Source engine attracts map makers, and there are lots of reasons for that. It is common knowledge that technology has moved forward since 2003, and many new game engines have found various techniques and methods to improve their renderings, making the Source Engine older and older. Nevertheless, it still has its very specific visual aspect that makes it appealing. The lighting system in Source is most definitely one of the key aspects to that, and at the end of this article you will know why.
About the reality...
Light in the real world is still a subject with a lot of pending questions, we do not know exactly what it is, but we have a good idea of how it behaves. The most common physic model of light element is the photon, symbolized as a single-point particle moving in space. The more photons there are, the more powerful light is. But light is in the same time a wave, depending on the wavelengths light can have all kind of color properties (monochrome or combined colors). Light travels through space without especially needing matter to travel (the space is the best example; even without matter the sun can still light the earth). And when it encounters matter, different kind of things can happen:
Light can bounce and continue its travel to another direction Light can be absorbed by the matter (and the energy can be transformed to heat) Light can go through the matter, for example with air or water, some properties might change but it goes through it And all these things can be combined or happen individually. If you can see any object outside, it is only because a massive amount of photons traveled into space, through the earth’s atmosphere, bounced on all the surfaces of the object you are looking at, and finally came into your eyes.
How can such a complex physical behavior from nature be simulated and integrated into virtual 3D renderings?
One of the oldest method is still used today because of its accuracy: the ray-tracing method. Just to be clear, it is NOT used in game engines because it is incredibly expensive, but I believe it is important to know how and why it has been made the way it is, since it probably influenced the way lighting is handled in Source and most videogame engines. Instead of simulating enormous amount of photons traveling from the lights to the eye/camera, it does the exact opposite. If you want a picture with a 1000x1000 resolution, you will only need to simulate the travel of 1 000 000 photons (or “rays”), 1 for each pixel. Each ray is calculated individually until it reaches the light origins, and at the end the result is 1 pixel color integrated in the full picture.
By using the laws of physics we discovered centuries ago, we can obtain a physically-accurate rendering that looks incredibly realistic. This method is used almost everywhere, from architectural renderings to movies. As an example, you can watch The Third & The Seventh by Alex Roman, one of the most famous CGI videos of all time. And because it is an efficient way to render 3D virtual elements with great lighting, it will influence other methods, such as the lightmap baking method.
OKAY LET’S FINALLY TALK ABOUT THE SOURCE ENGINE, ALRIGHT!
A “lightmap” is a grid that is added on every single brush face you have on your map. The squares defined by the grid are called Luxels (they are kind of “lighting pixels”). Each luxel get its 2 own properties: a color and a brightness. You can see the lightmap grids in hammer by switching your 3D preview to 3D lightmap grid mode.
You can also see them in-game with the console command mat_luxels 1 (without and with).
During the compilation process, a program named VRAD.exe is used. Its role is to find the color and brightness to apply for every single luxel in your map. Light starts from the light entities and from the sky (from the tools/toolsskybox texture actually, using the parameter values that has been filled in the light_environment entity), travels through space and when it meets a brush face:
It is partially absorbed in the lightmap grid A less bright ray bounces from the face Here is an animated picture to show how a lightmap grid can be filled with a single light entity:
When you compile your map, at first the lightmaps are all full black, but progressively VRAD will compute the lightmaps with all the light entities (one by one) and combine them all at the end. Finally, the lightmaps obtained are applied to the corresponding brush faces, as an additive layer to the texture used on that face. Let us take a look at a wall texture for example.
On the left, you have the texture as you can see it in hammer. When you compile your map, it generates the lightmaps and at the end you obtain the result on the right in-game. Unfortunately, luxels are much rougher, with a lower resolution, more like this.
On the left you have a lightmap grid with the default luxel size of 16 units generated my VRAD, a blur filter is applied and you obtain something close to the result on the right in the game.
In case you did not know, you can change the lightmap grid scale with the “Lightmap Scale” value with the texture tool. It is better to use values that are squares of 2, such as 16, 8, 4 or even 2. Do not go below 2, it might cause issues (with decals for example). Only use lower values than the default 16 if you think it's really useful, because you will drastically increase your map file size and compilation time with precise lightmap grids. Of course, you can also use greater values in order to optimize your map, with values such as 32, 64 or even 128 on very flat areas or surfaces that are far away from the playable areas. You can get more infos about lightmaps on Valve’s Wiki page.
But as we said before, light also bounces from the surface until it meets another brush, using radiosity algorithms. Because of that, even if a room does not have any light entity in it, rays can bounce on the floor and light the walls/ceiling, therefore it is not full black.
Here’s an example:
The maximum amount of bounces can be fixed with the VRAD command -bounce X (with X being the maximum amount of bounces allowed). The 100 default value should be more than enough.
Another thing taken into account by VRAD is the normal direction of each luxel: if the light comes directly against the luxel or brushes against it, it will not behave in the same way. This is what we call the angle of incidence of light.
Let us take the example of a light_spot lighting a cylinder, the light will bright gradually the surface - from fully bright at the bottom to slightly visible at the top.
In-hammer view on the left, in-game view on the right
Light Falloff laws
One of the things that made the Source Engine lighting much more realistic than any others in 2004 is the light falloff system. Alright, we saw that light can travel through space until it meets something, but how does it travel through space? At the same brightness, whatever the distance is between the light origin and destination? Maybe sometimes yes… but most of the time no.
Imagine a simple situation of a room with 1 single point light inside. The light is turned on, it produces photons that are going in all the directions around it. As you might imagine, photons are all going in their own direction and have absolutely no reason to deviate from their trajectory.
At one time, let’s picture billions of photons going in all the directions possible around the light, the moment after, they are all a bit further in their own trajectory, and all the photons are still there, in this “wave”. But, as each photon follows its own trajectory, they will all spread apart, making the photon density lower and lower.
As we said before, the more photons there are, the more powerful light is. And the highest the density, the more intense light is. Intensity of light can be expressed like this:
You have to keep in mind that all of this happens in 3D, therefore the “waves” of photons aren’t circles but spheres. And the area of a sphere is its surface, expressed like this:
(R is the radius of the sphere)
If we integrate that surface area in the previous equation:
With ♥ being a constant number. We can see the Intensity is therefore proportional to the reverse of the square of the distance between the photons and their light origin.
So, the further light travels, the lower is its intensity. And the falloff is proportional to the inverse of the square of the distance.
Consequently, the corners of our room will get darker, because they are farther away from the light (plus they don’t directly face the light, the angle of incidence is lower than the walls/floor/ceiling).
This is what we call the Inverse-Square law, it’s a very well-known behavior of the light in the field of photography and cinema. People have to deal with it to make sure to get the best exposure they can get.
This law is true when light spreads in all possible directions, but you can also focus light in one direction and reduce the spread, with lenses for example. This is why, when Valve decided to integrate a lighting falloff law in their engine, they decided to use a method not only following the inverse-square law but also giving to mapmakers the opportunity to alter the law for each light entity.
Constant, Linear, Quadratic... Wait, what?
In math, there is a very frequent type of functions, named polynomial functions. The concept is simple, it’s a sum of several terms, like this:
Every time, there is a constant factor (the “a” thing, a0 being the first one, a1 the second one, a2 the third one...), multiplied with the variable x at a certain degree:
x^0 = 1 : degree 0 x^1 = x : degree 1 x^2 : degree 2 x^3 : degree 3 ... And
a0 is the constant named “constant coefficient” (associated to degree 0) a1 is the constant named “linear coefficient” (associated to degree 1) a2 is the constant named “quadratic coefficient” (associated to degree 2) Usually, the function has an end, and we call it by the highest degree of x it uses. For example, a “polynomial of the second degree” is written:
Then, if we take the expression from the inverse-square law, which was:
With a2 = 1 and D being the variable of distance from the light origin.
In Source, the constant ♥ is actually the brightness (the value you configure here).
It is simply an inverse polynomial of the second degree, with a0 and a1 equal to zero. And we could write it like this:
And here you have it! This is approximately the equation used by VRAD to determine the intensity of light for each luxel during the compilation. And you can alter it by changing the values of the 3 variables constant, linear and quadratic, for any of your light / light_spot entity in your level.
Actually you set proportions of each variable against the other two, and only a percentage for each variable is saved. For example:
By default, constant and linear are set to 0 and quadratic to 1, which means a 100%quadratic lighting attenuation. Therefore, by default lights in Source Engine follows the classic Inverse-Square law.
If you look at the page dedicated to the constant-linear-quadratic falloff system on Valve’s Wiki, it’s explained that the intensity of light is boosted by 100 for the linear part of equation and 10 000 for the quadratic part of equation. This is due to the fact that inverse formulas in equations always drop drastically at the beginning, and therefore a light with a brightness of 200 would only be efficient in a distance of 5 units and therefore completely pointless.
You would have to boost your brightness a lot in hammer to make the light visible, that's what Valve decided to make automatically.
The following equation is a personal guess of what could be the one used by VRAD:
With constant, linear and quadratic being percentage values. The blue part is here to determine the brightness to apply, allowing to boost the value set in hammer if it is as least partially using linear or quadratic falloff. The orange part is the falloff part of equation, making the brightness attenuation depending of the distance the point studied is from the light origin.
The best way to see how this equation works is to visualize it in a 2D graph:
This website provides a great way to see 2D graphics associated to functions. On the left, you can find all the elements needed with at first the inputs (in a folder named “INPUTS”), which are:
a0 is the Constant coefficient that you enter in hammer a1 is the Linear coefficient a2 is the Quadratic coefficient B is the Brightness coefficient In another folder are the 3 coefficients constant, linear and quadratic, automatically transformed into a percentage form. And finally, the function I(D) is the Intensity function depending on the distance D. The drawing of the function is visible in the rest of the webpage.
Try to interact with it!
This concludes the first part, the second part will come in about two weeks. We will see some examples of application of this Constant-Linear-Quadratic Falloff system, and a simpler alternative. We will also see how lighting works on models and dynamic lighting systems integrated in source games.Thank you for reading!

Pampers reacted to Rick_D for an article, Making Agency, the popular CS:GO map
What is Agency?
Just in case you have never heard of Counter Strike: Global Offensive, it's a hugely popular online FPS, successor to Counter Strike: Source and the original Counter Strike. The original came out in 1999 and the core gameplay has remained almost unchanged. Players are split into two teams and challenge each other in various game modes such as Bomb Defusal (one team has to plant and detonate the bomb while the other tries to stop them) and Hostage Rescue (one team must rescue the hostages whilst the other attempts to prevent that). The Bomb Defusal mode is by far the most popular, with maps designed with such detail that players can predict down to the second when another player is due to arrive in a certain area of the level. It's also the only mode played in competitive events and for huge prize money.
This leaves the poor Hostage Rescue mode sitting on the sidelines twiddling it's thumbs and feeling a little rejected. In part this is because the Hostage Rescue mode is far more of a roleplaying experience, often with very poor odds of success for the team tasked with doing the rescuing. Often the levels are designed in such a way that the defending team has a large positional advantage, where simply staying-put will give them a good chance of winning.
That's where we can start talking about Agency. Agency is a Hostage Rescue level, created as a collaboration between level designer Patrick Murphy, and myself doing the art. The basic idea being that Hostage Rescue could be just as precise and exciting as Bomb Defusal. It's been included in three official releases from the games creator, Valve, as part of their community level packs: Operation Bravo, Operation Phoenix and Operation Bloodhound. Phoenix being a community-voted choice, which was especially great to see that players enjoyed the style of gameplay and visuals that Agency brought with it.
In this article I will go over the process of creating the art, from props to set dressing, texture creation and lighting, while maintaining a visually pleasing aesthetic and serving to enhance the gameplay. This isn't a postmortem but rather a walk-through of the various stages, hopefully to give some ideas to others, with lessons learned both positive and negative.
Iteration from Whitebox to Final
Starting out you should always have an idea of what you're going to create, even if it is quite vague, as it'll point you in the right direction for both creating architectural spaces and letting your imagination fill in the blanks as you build the basic shapes of the level. We knew we were going to build an office space, but style was leaning towards an older government building with red bricks and musty wood. As I started to put in some basic textures we decided it felt too bland, and similar to other levels in the game. In order to stand out and create something really interesting and intriguing that would entice players to want to explore the level we decided to modernize the space and use white as the primary colour - this would help players see each other more easily and provide a striking visual setting it apart from other levels.
"Modern Office" is not exactly a style that has a single look, if you search for images you'll get back a lot of contrasting designs and ideas, trying to put every single one of those into a level would create a visual mess with no consistency. It's important to choose the right references for what you are building, something that looks cool in a single image or from a specific location might not fit into the theme of the level, and in a worst-case-scenario it might actually start to detract from the level as a whole. Trying to cram in as much content as possible simply makes your level feel less unified and jarring.
Unfortunately when you are presented with so many fantastic designs and ideas it can be hard to pick out what is important. After settling on the location: a modern advertising agency's office, I broke down the needs of the level into a few different categories:
Area Specific General Use Overall Theme The Area Specific content is "hero assets" for each location in the level. These are the things that help the player tell different areas apart from each other, a reception desk, a kitchen, a bathroom, etc. Assets that won't be used anywhere else except in their specific location.
Examples of Area Specific Content
The General Use content is the backbone of the building, it's wall sockets, ventilation tubes, sprinklers, desks and chairs. The things that could be used anywhere and would blend in to the background and not stand out unless you were specifically looking for them.
Examples of General Use Content
The Overall Theme content is what sells the theme of the level to players, advertising boards, company logos, large art installations and so on. These can be used everywhere but sparingly and should only be used as a subtle reminder to the player of where they are thematically. They shouldn't detract from the Area Specific content but should stand out more than the General Use content. This came in the form of abstract paintings, corporate logos, rotating advertisement panels and so on - things that would subtly tie the level together.
Once these categories were laid out, searching through reference images became much simpler as you know what you need and only have to find an interesting design or detail that enhances a specific category.
This isn't to say that everything was completely planned out or that development was flawless. Sticking to a plan only works until you open the editor, and if you try to force something you'll end up frustrated when it consistently fails to work. As an example we originally had the level set on the ground floor of a tall skyscraper. I spent a few weeks working on content for the ground but never really getting it to feel right within the theme of the level: the contrast between a dirty exterior street section and a spotless interior didn't feel right for the level, and felt a little too similar to another Counter Strike level. Patrick played around with some ideas and tried something I was afraid of: simply deleting everything I had done on the outside and adding an epic city vista. Instantly it felt right. The important thing to take away from this is that just because you have worked on something doesn't mean it's the right thing to be working on, and that getting input from other people with different ideas can vastly improve what you are working on.

The same space after an art pass
Another incredibly important thing I realised is making use of modular assets. If you are going to duplicate something in your particular modelling software you should ask yourself: is this efficient? Chances are you're just making things harder to change later and locking yourself into a particular shape; eg: a walkway has a railing around it, you model the entire railing as a single object. Now if you need to change that walkway a month later you're going to have to go back and change your railing model. It's better to create a smaller tiling mesh that can be used multiple times, as often you'll find you can use that model in other areas and in different ways than you had initially intended. You're simply applying the concept of tiling textures to models, and in the process saving yourself a lot of time.
A Believable Clean Art Style
Creating a clean environment can often be more difficult and time consuming than a very dirty and cluttered one, simply because any mistakes are magnified by the lack of other objects to disguise them. A room with a single chair in the middle is going to end up with the focus being on that chair, if you fill that room with a hundred chairs you're going to be less concerned with the details of the chair and more worried about why someone would fill a room with a hundred chairs.
In the modern office setting of Agency it would have made little sense to fill it with props and clutter, but a large empty space would just feel unfinished. A delicate balance of larger architectural shapes and smaller objects was needed. I like to think of this as functional art: it serves a purpose in the lore of the game world. Window and door frames, electrical sockets, thermostats and card swipes along with the maintenance apparatus of ventilation systems. These are the general use objects mentioned earlier, they fill out space and prevent an empty wall or ceiling from actually looking empty and at the same time they contribute to the believability of the level. It's important to think of the infrastructure of the building when placing these assets - if a wall has an air vent on it then the wall needs to be thick enough to support the ventilation pipes that feed it, Card swiping mechanisms need to be placed near doors at the correct height, electrical sockets should be placed logically in areas where they would be of use to the fictional inhabitants of the level and so on.
Several examples of functional art details
One of the most important things to do right when creating clean environments is to get the most out of the materials. It's not possible to cover every surface in dirt or decals, so the surfaces themselves become your way of showing detail.
For Agency this was achieved by making liberal use of the phong shading techniques in the Source engine for models, and cubemaps for world textures. Almost all models in the level have some amount of phong shading, and although it doesn't produce a completely physically accurate result it can be used to create materials and surfaces that look relatively accurate. Simply by increasing or decreasing the intensity of the phong amount allowed for a vast majority of the levels surfaces to be rendered accurately. As I didn't need to have a lot of noisy detail in the materials due to the clean style I simply used a small phong texture as a mask for 75% of the models and let the lighting and general shapes of the models do the rest of the work.
Simple phong shading to mimic real world materials
As most of the surfaces had a single layer of material, ie paint or coloured metal, the phong shading could be completely even without breaking the illusion; however some of the dirtier surfaces such ventilation tubes and water pipes had several layers: a painted metal surface with area peeled away to reveal with metal underneath or a layer of dust. These had specific masks that would enhance the different materials, and showing wear and tear in the background assets added an extra layer of depth without compromising the clean style.
Most of these textures were created with dDo, an excellent tool for quickly creating textures. I generally started with quite a dirty texture preset and toned down the details and noise until they were barely perceptible surface imperfections.
Agency features probably close to 95% custom art, and that's a lot of work for a single person. Using dDo allowed me to make a lot of content relatively quickly, and kept it all visually consistent.
The process of creating the assets with dDo was quite simple: first I modeled the basic ingame asset, then did a very quick and dirty placement of edge loops that allowed me to smooth the mesh and get a workable high poly. A very rough normal map was baked (along with a more solid ambient occlusion map), this rough normal map would never make it into the game, it was used purely for texturing with dDo. This rough-and-dirty technique was mostly used on the more general purpose assets that nobody would spend a lot of time looking at. For the objects that were in high traffic areas or that required finer detail a more robust normal map was created.
Tiling textures used throughout the world were photo-sourced and tiled in Photoshop. A few examples worth pointing out are the plaster wall textures and the marble floors:
The image above shows the ingame result, the diffuse texture, and the normal map of the standard plaster that is used throughout the level. The normal map was authored at 1024x1024 compared to the diffuse texture which was 512x512. I created several colour variations of the diffuse texture and for a very plain surface using a 1024x1024 diffuse didn't make much sense. The final touch was to add a subtle cubemap effect to bring out the normal map and add interesting coloured reflections in various areas.
Another example is a marble floor used throughout the level. The normal map is unrealistic in that it portrays an uneven bumpy surface when in fact it is more likely to be uniformly flat. However to break up the reflections and add some visual interest to such a large and empty area I added a subtle bumpy normal map which warps the reflections, but is subtle enough that it doesn't get picked up by the lighting and actually appear like a lumpy mess.
Good shading only gets you part of the way there, however. A poorly scaled model can break immersion instantly, especially when you are trying to create a believable real-world environment. There are tried-and-true metrics for Counter Strike so having a base to work from helped immensely, but these only give you a good starting point or a bounding box for your object. It's important to study real world reference and make sure your object is proportional to the world around it and also to itself. A unit in Hammer is an inch, so having wood that's 2 units thick, or a doorway that is 1.5m wide quickly makes things look wrong.
Working with Designer Blockouts, and not Destroying Gameplay
Agency was a collaboration, with Patrick doing the design work and me doing the visuals, this meant there was a lot of potential for overlap and working on the same areas, the potential for breaking things was huge.
Often when you create things as an individual you don't have to worry about version control or stepping on someone else's toes, however when you work with other people either for pleasure or business you, as an artist, need to change your mindset. You are not creating a portfolio piece but rather something functional that has to withstand hundreds of hours of real people playing it.
Your first role is to support the designer, and this benefits you as well. By creating the basic structures of the level: doorways, window frames, stairs, railings, cover objects etc, you are allowing them to work with the final assets and tweak gameplay according to those assets. Nothing needs to be finalized instantly, it's better to provide a rough mockup of the intended asset so the designer can play around with it and give feedback on the shape, size and silhouette. Once you are both confident it's going to work they can populate the level with these assets which saves you time in the long run, and once you finalize the model and textures they are going to be updated across the entire level without having to manually replace assets.
It can be difficult to determine exactly when you should start an art pass, especially when a level is constantly evolving. Rather than sitting idly by whilst Patrick was ironing out the design of the level I started on the creation of a few visual test levels to explore materials, lighting and modular assets. Once the first iterations of Agency were created, with rough shapes for important cover and controlling lines-of-sight. I went in and created an art pass and altered many of these original gameplay ideas, simply experimenting with different shapes and designs for the rooms. We had a constant dialogue and never considered something finalized just because it was finished. Playtests would determine whether an idea was valid or not in a way that speculation can only hope for. The most important lesson learned during this process of constant iteration was that work is very rarely wasted, and it is far more important to stay true to a gameplay ideal than to have an area that looks interesting in a screenshot but utterly fails when players get their hands on it. A box is a box is a box, it is down to you as an artist to imagine how that box can be interpreted within the context of the environment.

An important part of any environment is the lighting. Too contrasted and moody and it becomes hard to identify players, too bright and monotone and it becomes boring and a strain on the eyes. For Agency I used a series of instanced lighting setups: a model to visualise the light source, a spot light to direct the light, and a sprite or light cone to add a visual effect around the light. Each light setup was unique to the type of model used for the actual light source, ie: all spotlights were identical, all fluorescent lights were identical etc. This meant I could change a single light and have the others update automatically, and always get an accurate result.
Then it was just a case of placing these different types of lights where they logically made sense in the environment, and if an area was too dark an appropriate light source was added, and if an area was too bright lights could be moved around or removed entirely. This made it quite easy to light as everything was guided by reality, which has plenty of reference material, and had the side effect of helping to make the environment more believable. By using various colours on the floor and walls I could direct lights towards them and take advantage of the Source engine's excellent radiosity and spread interesting colours to nearby surfaces.
In many areas the ceiling was opened up to reveal the sky and to let natural sunlight into the interior spaces, this was done to provide contrast to the electrical lights and to get extra radiosity bounces into the environment. Some areas had lights removed or toned down to allow other more important gameplay areas to stand out, for example the image below shows how the corridor here was darkened both by using darker textures and by using restrained lighting to make the room in the distance appear brighter as this is an area that enemy players will appear from.
This could have been taken even further by possibly using emergency exit signs to add hints of colour to important gameplay areas and chokepoints. A consistent lighting language would have helped guide players during the first few times playing the level. There are some large open spaces that would have benefited from some coloured screens or lighting panels, or possibly making some of the larger glass surfaces tinted, to add a little extra colour and prevent such a monotone look whilst not being over-bearing or detracting from the realistic style of lighting I was aiming for.
During the course of developing Agency I had a chance to learn a few things and come out the other end a, hopefully, better artist.
So, what went well?
The iteration process never had any hiccups, by using modular content and being prepared to discard ideas and art styles that weren't working we ended up with a better level. If we had tried to force the original idea of a ground-level government office we would have ended up with a completely different level, complete with underground parking lots and elevator shafts. Exciting stuff!
The power of iteration cannot be understated, and understanding that a mockup or a blockout of a level is simply a temporary phase that doesn't represent the end result. Areas changed drastically between versions, sometimes due to design requirements, and sometimes of shifts in art style; but each version was better than the last, more refined and polished.
What went less well?
In direct contrast to the statement above, sometimes the iteration interfered with more important tasks. I got stuck on areas trying to get them to work instead of letting them sit for a while and returning to them later. I tried to force an idea for the exterior part of the level and it never felt right and consumed way too much time, when all it took was getting some outside perspective. Luckily during the process I learnt to trust designers when it comes to art, just because they might not build high poly meshes doesn't mean they aren't artistic.
Another problem was building too much content completely unique for an area which meant when we inevitably changed things it became time consuming to shift assets around, and makes it less easy for others to re-use that content without creating an almost replica of the area it was designed for. These unique assets helped sell the realism of the level but made them harder to work with.
Hopefully this has been interesting and insightful!

(Art by Thurnip)
/r/GlobalOffensive and Mapcore are teaming up to grow Counter-Strike: Global Offensive’s mapping community!
Check out the reddit thread for this contest »
The Big Reveal
We’re hosting a map-making contest for original, competitive 5v5 bomb defusal maps AND competitively-minded hostage maps, open exclusively to mappers who have not yet had their work featured in a Valve Operation!
Older projects are fair game: now’s the perfect time to polish up that map you’ve been working on but never got around to finishing. Experienced Mapcore judges and prominent members of the Counter-Strike community such as Sadokist, Moses, DDK, James Bardolph, and Anders Blume will be weighing in – but only one map can win it all.
Every week for the length of the contest, eligible maps will be playtested during /r/GlobalOffensive community nights according to a sign-up schedule. Slots on this schedule will be filled on a first-come, first-serve basis following an approval process, but we will try our best to accommodate everyone at least once. However, because it’s impossible to guarantee that all contest entries will have the chance to be playtested, /r/GlobalOffensive playtesting is a supplemental, helpful tool which will have no bearing whatsoever on contest judging.
You can register for a playtesting slot here. Remember -- playtesting registration is first-come, first-serve!
Enter Your Level
To officially enter your level into this contest, post a WIP thread with a link to your level’s Steam Workshop page in Mapcore’s official event forum.
Posting a WIP thread with a link to your level’s Steam workshop page constitutes your official entry into the contest, however you don’t need to do both at the same time. In other words, you can post your WIP thread and then update it later with your workshop link if you’re not ready to go right away. You can also feel free to continue updating your workshop level after you’ve posted your workshop link – contest entries will not be judged until after the submission deadline.
Your level must be submitted to Mapcore by August 31st, 2015 at midnight Pacific Standard Time (PST).
Our panel of judges will then select four finalist levels based on the following criteria:
Fun factor Visual/thematic presentation (graphics) Overall polish
Grand Prize Deadline
After the top four maps have been announced, /r/GlobalOffensive users will put them to the test!
Once all four finalist maps have been tested, mappers will have two weeks to revise their work based on community feedback. After those two weeks, an official Grand Prize Winning Map will be chosen!
The goal of this event is to raise awareness about Mapcore's incredible level design community and the incredibly useful playtesting capabilities of /r/GlobalOffensive. Both Mapcore and /r/GlobalOffensive are free resources available to all mappers. To date, Mapcore users are responsible for creating more than 70% of Valve Operation levels. Mapcore’s staff are unpaid volunteers, and do not personally profit in any way from additional traffic to the site.
Of course, it wouldn’t be a contest without a reward… In addition to the helpful feedback and free publicity that CS:GO mappers will receive by participating in this event, each finalist will also receive:
Eternal Bragging Rights™ and a showcase on Mapcore (where their level will be highly visible to industry-veteran game developers and the rest of the community) A monetary prize ($1000 + Mapcore swag for first place; $400 for second place; $200 for third place; $100 and Mapcore swag for fourth place) The top-finishing map will also be played in a competitive show-match casted and streamed by goRGNtv, for all to watch and enjoy! *NEW* CEVO has generously agreed to host the winning map in their PUG rotations for one month! *NEW* Added $1,000 to prize pool thanks to Gamebanana.com and EGO DEATH (gun skin creator) *NEW* Valve prizes!

Pampers reacted to Sentura for an article, Exploring Unreal Engine 4 Scripting: Part Two
Now that you've had a month to digest part one of Sentura's dive into the lovely world of Unreal Engine 4, it's time to get your teeth into the second part. This time, discover the wonders of debugging, comparisons, and casts. Also, feel free to use the comments to ask further questions about this tutorial or Unreal Engine 4 in general.
Picking up where we left off, let’s take a look at debugging, comparisons and casts.
There were some issues with our door example in Part One, which I glossed over for the sake of simplicity. Now, however, our door should serve as a useful example of how to debug blueprints.
The problem was that our door didn’t really open properly, as seen in this image:
Let’s figure out what’s wrong with some debugging.
There are many methods of debugging blueprints, of which Breakpoints are the most common. Setting a breakpoint stops execution of your game momentarily, allowing you to inspect the nodes of a blueprint graph. This is tremendously useful for squashing any troublesome bugs.
Breakpoint debug steps:
Add a breakpoint. Play and execute the event (the game pauses and focuses on your breakpoint). Use the step button to go through the execution step by step. After a few steps in our door example, we see that both of our events are being triggered repeatedly. We can also hover over any variables and parameters to examine their specific values at the time of the break.
Another method of debugging is to split your screen (or simply use two monitors), separating the blueprint window from the game window. This helps track what’s going on in the graph as you walk through your door. This way, we can see the exact point the execution reaches while we play the game, although we aren’t provided with any additional information.
Notice that the drop down menu next to the play button in the blueprint graph window needs to be set to our specific door in order for it to display any information about the door.
Both of these debugging methods help us trace the root problem with our door example: events are registering repeatedly, causing the door to behave erratically. One guess as to why this may be occurring, is that some native player character components are interfering with the door blueprint by forcing it to register more than one actor.
How can we single out an object or actor to ensure that it’s the correct target of a sequence? How can we ensure that any given object or actor is actually the intended type, in order to avoid problematic misidentifications? These are questions which can be answered using comparisons.
Comparisons are, just as the name implies, a way for us to compare objects in order to determine whether or not they are alike. UE4 determines the result of this comparison with a boolean value – either the objects are the same (a boolean true value) or they are different (a boolean false value), and we can then use this boolean as an indication of what to do with our door. In UE4, conditions are done through the branch node.
The node used for comparisons is called “Equals”. Note that there are several versions of the “Equals” node, as it can be used for almost all possible variable types.
Now that we have our Equals nodes, we want to make sure that they are configured correctly. Each event needs an equals node, taking the ‘other actor’ parameter and comparing it with the player controlled pawn – our First Person Character actor. While you can link the First Person Character actor through other ways, doing it this way ensures that even if we change the player actor to something else, the door condition will still hold true.
This solution wraps up nicely and leaves no room for error. But it is also somewhat limited: What if we also want to make potential enemies pass through the door?
Casting is a term originating from the computer science concept of polymorphism. In short, polymorphism is about class relationships, and how some classes may have a more generic version of themselves stored to use for implementing a variety of classes within the same skeleton. The generic class is called a superclass, whereas the class inheriting data from the superclass is called a subclass.
The classic example of this is that a Car subclass would have a more generic Vehicle superclass. In games, this idea is even more widespread: we could have a Weapon superclass able to shoot and reload, but what happens when the weapon shoots and reloads would be up to the subclass. An RPG subclass would naturally have a different implementation than a SMG subclass, although it would share attributes like ammo and functions such as shoot or reload. Subclasses still have their own independent functions alongside inherited functions.
How is any of this relevant to Blueprint? In short, a subclass inherited from a superclass may be targeted through its superclass. If you cast to a Weapon superclass, then any of Weapon’s subclasses can pass through as well.
Let’s tie all of this together: using the superclass of First Person Character Character, we could ensure that all classes inheriting from Character are able to use a door as well – including our currently nonexistent enemy characters.
There is a caveat: casts are performed during runtime. This means objects or actors which cast incorrectly could crash or otherwise break your game. For a more technical understanding of why casts should be used carefully, I recommend this article: http://stackoverflow.com/questions/4167304/why-should-casting-be-avoided
So far, we have only briefly touched upon the concept of polymorphism, but it is one of the most important concepts within an object oriented programming paradigm such as Blueprint, and a great tool for creating system architecture (including system design).
There is no article for polymorphism in UE4, and I’m tempted to write a comprehensive guide. In the meantime, you could take a look at this short video explaining the concept more thoroughly:
Video no longer available on youtube
In the third and final article in this series, we’ll implement a grenade weapon (using some polymorphy) and a grenade throwing mechanic using Bezier curves.
See you then!
Pampers reacted to Sentura for an article, Exploring Unreal Engine 4 Scripting: Part One
On the other hand, UE4 has also been somewhat stripped of “default” content in order to emphasize the user-generated content located on Epic’s new marketplace. This tutorial series is designed to bring you up to speed on UE4 level-design by showing you how blueprints work and how you can create your very own blueprint building-blocks.
Understanding Blueprints The Blueprint system is a visual scripting language central to all game interaction in UE4.
Blueprints come in two flavors: Level blueprints and Class blueprints. Level blueprints are attached to your level, whereas Class blueprints are self-contained templates for a single type of object in your level (a “class”) only. Anything you do in a Level blueprint can also be done in a Class blueprint, but Level blueprints additionally enable you to set up communication between multiple Class blueprints.
Let’s take a look at what actually goes on inside these blueprints.
Inside Blueprints Let’s start with the two basic blueprint nodes: Functions and Variables. Variables can be explained as containers of object data, while functions essentially perform game logic upon variables.
The next section will cover these nodes in more detail.
A Player variable with a Jump function. As illustrated, executing the function (f) causes the player to jump
Object Data (Actors and Variables)
Although they are very versatile, variables are most commonly used to control actors, objects that exist inside the game world. Characters, weapons, doors, switches are all examples of actors. Additionally, every actor’s variables can potentially be manipulated by functions, for example the health of a character stored as an integer value.
A actor variable (player) with health and position stored as an integer variable (green) and a 3D-vector variable (yellow), respectively
Actors can also contain components: other actors incorporated inside the main actor. This enables static meshes to have component collision boxes, or to be paired with component particle effects, among other things.
The components of this door object are two meshes (a door and a doorframe) and a collision box that helps control the door’s physics behavior
Functions are nodes of logic which can be executed (called) to perform a certain task. If something needs to take place in-game, such as a player picking up a weapon, functions can enable as well as add additional consequences to that action.
A function execution string (the white line)
Functions present and modify variable information. For example, a function which acts upon information gathered by a variable could teleport players to specific game-world coordinates. A ‘getter’ or ‘pure’ function, on the other hand, merely relays information for use elsewhere, such as reporting a player’s current coordinates in the game world.
A ‘pure’ function (green). Notice that ‘pure’ functions do not have independent execution, only when linked with a regular function (blue) does this particular function have effect
So, we’ve covered Variables and Functions. But how does the Blueprint system know how and when to react to incidents inside the game world?
Events allow different actors to communicate with each other. For instance, an event controls when an actor collides with another actor, or what an actor should do if a collision actually occurs. More examples of an event are a door opening as a character nears it, a switch being thrown, or a barrel exploding after it has taken sufficient damage. An example of an event could even be as fundamental as a player using controls to move their character model. Customized events can be called much in the same way a function would be.
Event (red) called if an actor is hit. The event triggers a function linked to taking damage. This example is intended for learning purposes, not for practical use
Quick aside: In general, as a good practice, variables, functions and events should be named for their exact purpose. This helps both you and others read what’s going on in your blueprints. An actor named “player”, or an integer named “health” is easier to understand than one named “asdhjkashdj”!
For more information on variables, functions and events, please refer to Epic Games’ own documentation, which provides encyclopedic knowledge about the topic.
Case study Now that we understand the building blocks of UE4’s Blueprint system, let’s look at a practical example: the Class blueprint of a sliding door (If you want to create your own sliding door, I recommend taking a close look at Epic’s in-depth guide.
When a player gets close to it, the door opens. When a player leaves the door’s vicinity, it closes. Let’s examine the door’s blueprinting:
You can see that the door actor is composed of several components: a frame object, a door object and a triggering box
In this image, we can clearly see the nodes used to trigger the door’s opening and closing. For example, the event OnComponentBeginOverlap triggers once a player steps into the Box component actor listed. That triggered event starts executing anything along the execution logic path, such as the Timeline function and the Set Relative Location function.
The Timeline function changes an integer with decimals - the Driver float variable – between 0.0 and 1.0 over time, and sends execution updates every time the float changes. The float variable is called Driver in this case, because it drives the door to either open or close. The Lerp function’s Alpha parameter then uses this float value to determine the exact position of the door between being open (float value of 1.0) and closed (float value of 0.0). The Vector variables Door Closed Position and Door Open Position are end points for Alpha to blend between. This is to ensure that the door opens and closes smoothly over time rather than instantly.
Set Relative Location then executes the data received from the Lerp at intervals put forward by the Timeline’s update execution for the door that we use. The result is a door which slides opens when players are nearby.
Lastly, our OnEndComponentOverlap event triggers the closing of the door by reversing its operation when players leave the triggering box.
Here you can see our moving door in action:
To be fair, this case study is a bit over-simplified in order to provide an example that can be easily understood. The real version of this door (which will be shown in the next part of this series) is a bit more advanced, but its core principles are exactly the same.
So far, we’ve covered the structure of variables, functions, events, as well as a common gameplay element like a sliding door. In the part two of this tutorial series, we’ll learn some more advanced blueprint features, such as class recognition, level blueprints and blueprint communication.
Thanks for reading!
Pampers reacted to Thrik for an article, RaiseTheBarVille, our joint Half-Life Mapping Challenge
Your objective We'd like you to re-imagine a scene of your choosing from any of the Half-Life games. To be clear, we're not looking for remakes of scenes — we want you to completely reinterpret a scene, approaching it from a fresh perspective. You can, however, use assets from Black Mesa.
Here are some examples of ideas you could develop:
The Tram ride at the beginning of Half-Life. What if somebody else pushed the cart? Gordon was late, so they got somebody else and the resonance cascade happens when Gordon is still on the tram. It crashed to the ground but leads him to a previously unseen section of Black Mesa. Black Mesa. What if Half-Life's infamous research facility were hidden underneath a city or town rather than out in the desert? Surface Tension. This particular event occurs on the side of a Citadel. Yes, it doesn't fit the story, but that's not important. This is about high cliffs and long falls. Opposing Force. What if Black Mesa were devastated by this game's nuclear bomb quite early on during the story, leaving Adrian Shepherd to navigate a version of the research facility resembling a post-apocalyptic nightmare? Point Insertion. Instead of arriving at a city train station, Gordon finds himself in a deserted and derelict village station, perhaps near enough to Ravenholm, to feel the threat. Being seen by Civil Protection may be the least of his worries. City 17. What if the Combine had chosen the United States, France, or London to be their primary city? The only limitation is your imagination, which we want to see run wild — create the most wonderful interpretation of Half-Life's universe that you can conceive. Whether your project is big or small, you should strive to create something that will delight Half-Life fans.
How to share your progress Because this is a joint challenge, there are two places for this:
Where you may discuss the challenge and share progress of your work, which we hope that you will! RunThinkShootLive challenge article
Where you can do the same. Both will be compiled together for judging and articles after the challenge ends, so you don't need to post in both places (although it's not a problem if you do).
Prizes Prizes are being donated by both MapCore and RunThinkShootLive, in addition to your work being immortalised in our archives for others to enjoy.
For the winner
A lightly used hardback copy of Valve's rare Half-Life 2 development book, Raising the Bar, kindly donated by Don aka Unq. This book is a must-read for any fan of the game, and particularly those interested in its development process. In addition to being a collectable in its own right, this particular edition is signed by Valve staff, arranged by a friend of Phillip's who works there.
For the almost-winner
Don't feel bad, you nearly made it. Have a plush companion cube plus a MapCore mug or t-shirt, and know that we love you.
...and for everyone else
All entries, except the winner and almost-winner, will be entered into a random draw to win Sniper Elite 3.
Challenge dates Begins: Thursday, 19th March, 2015 at 11am GMT
Ends: Tuesday, 28th April, 2015 at 11am GMT
Rules You can't have a challenge without rules, right? Here are the requirements:
Maximum one map per mapper per entry. The map must have at least one enemy and one weapon; i.e. playable. The map must be original and not have been released publicly before. The map must run in a system with only Half-Life 2: Episode 2 installed By entering the competition you grant RunThinkShootLive.Com and MapCore.org the right to release the map as part of the RaiseTheBarVille Mod. Maps must not appear for download before the release and for one month after the release of the mod. No assets from retail games other than Half-Life 2, Half-Life 2: Episode 1 or Half-Life 2: Episode 2 are allowed. Other assets are allowed with written permission from their original authors, which must be included in the entry. The organizers' decision is final and no correspondence will be entered into about it. The map must have a proper name. The map must have a proper filename: MapName_rtbv.bsp Each entry should be accompanied by a correctly formatted (vtf) background and chapter image. The name is not important, as it will have to be changed. All entries must be sent to: [email protected] no later than the deadline. Frequently Asked Questions There have been a few questions asked about this challenge, so hopefully this will help you. However, if your question is not here and you have doubts, please don’t hesitate to ask, no matter how small your query.
Can I use assets from Black Mesa Source?
Yes, by all means, but you must pack them into your BSP. Yes, we know that may mean redundancy, but the map MUST run in a system that ONLY has Episode Two installed. We don’t want to force players to download BM.
Can an entry be a joint entry?
Yes, but there I still only one prize. You’ll have to fight to the death to decide who gets it.
Which games can I re-imagine?
Half-Life, Opposing Force, Blue Shift, Half-Life 2, Lost Coast, Episode One, or Episode Two.
Can I use assets from Lost Coast?
Yes, pack them into your BSP.
What about recreating a scene that was say… cut from one of the main games? Technically a re-imagining of a re-imagining.
No, but you could use the cut area as inspiration for something that was released in one of the games. What we don’t want people to do is remake a cut section from a game.
Can simply change a location?
Well, yes, but again, there should be some element of “What if…?” in the map. Simply changing a town for a city is only part of what we are looking for. You map should really be the result f some change, however minor, in the story.
How do you define a scene?
In the context of this challenge a “Scene” is a part of the game that has some effect on the following game. So, changing one location for another is not really enough. What we are looking for is something that takes the game in a different direction.
Can we submit mini-mods instead of a map?
Sorry, no. Your entry must be a self contained map.
Can I submit something artsy?
Sure, but it must have at least one enemy, one weapon and a player spawn.
Can we decompile or remake specific locations from Valve maps?
We think it’s best if we disallow this. Mainly to avoid any potential problems. Please start your map from something new. However, we will allow a very small section if this is just used to “fit into the story”. For example, in Episode One, at the beginning when Alyx and Gordon are thrown into the Citadel. If you map started at the bottom but then things went very differnt from the game, that would be okay.
How should I start my map?
We suggest a little text at the beginning to set the scene. Something like…”What if Gordon were late and somebody else push the cart? Let’s find out“. It’s not compulsory but it might help.
What’s the limit of changes we can make?
Wow, that’s a tough question. Your changes MUST NOT affect maps that may be after yours in the final mod.
My question is not here, what should I do?
Ask in the RTSL post or MapCore thread. Somebody will respond quickly.
Closing words We really hope that you have fun with this. MapCore has a very long history of facilitating development of levels for Half-Life and its mods, in fact we were founded around that very concept. As such, we're hopeful that the community still has that passion for one of gaming's finest classics, and is keen to apply modern-day skills and technologies to bringing Half-Life's universe to life — because Valve sure isn't doing it any time soon!

Pampers reacted to Furyo for an article, Level Design in The Last of Us: Part Two
This is the second article in a three-part series. Part One / Part Two / Part Three
First Level The intro cinematic here serves two purposes: Introducing Tess and her relationship with Joel, and giving players a goal for the upcoming level. With that done, it’s not necessary to give players other intermediate goals along the way.
Follow Mission Following an NPC is an excellent, tried and true means to expose players to a completely new world to discover. Tess plays the role of a learning tool, and it’s precisely once players have learned enough about survival in the game that she dies and leaves room for the new relationship between Ellie and Joel to grow. This is an absolute classic process - death aside - used in a great many third person games from Uncharted to Prince of Persia, Enslaved and many others. FPS games also use this technique, but to a lesser degree as following an NPC in first person is often a much more arduous task. Half-Life 2 famously used Alix Vance that way, mostly in non-combat spaces. More recently, BioShock Infinite also followed the same model but made the entire game about that NPC.
Once outside, players are immediately presented with a good combination of narrative and level design. Tess mentions the curfew that will hit in a few hours, while in the same frame, players can see once again in yellow, the sign that mentions the curfew hours. Attention to small details like that is what will make an entire world more believable. The use of red and white bricks for these buildings adds contrast and depth to this scene, and with Tess going around the corner, helps imagining the path forward.
Messages painted across walls is as fundamental a narrative design technique as any, but great games will make use of them sparingly, and at the very least won’t reuse the same message more than once per section, so as not to destroy the immersion they’re designed to create. It’s the same thing for talking NPCs, designed for very specific situations, so their speech doesn’t get repeated.
During this entire level Tess keeps waiting for the player by staying idle on a few of the nodes on her scripted path. This is of course so she can keep being the player’s guide. Notice here however that the implementation of that system is just the bare minimum expected in today’s games. In reality, follow missions are few and far between in this game, as NPCs usually trail behind the player in non-scripted ways. In a game where the NPC is as essential as BioShock Infinite, Elizabeth would have stopped her scripted movement, retraced back her steps to the player (or been teleported behind him) only to resume her script from there. This is a good example of the limitations borne from early creative decisions that dictate the systems developed for the game. It’s entirely normal, but something to be conscious of when creating levels.
Following on to the main street, where a scripted camera takes over and introduces the new playable zone. This sort of introduction is a dead giveaway of a Naughty Dog game, and is most useful in locking the player in place while the army vehicle passes left, preventing the player from reaching the far end gate and exiting the playable area. With the camera locked in this way, the vehicle may very well simply disappear once passed.
Arriving in a large area is often a good occasion to introduce more exposition scenes, and in this case two well-constructed ones. Right in front of the player as he arrives, the first scene presents survivors waiting for their weekly ration in a line, behind fences. The fences here work great with the theme of a post-apocalyptic world, but the wall they form is absolutely necessary in scenes like this to limit player interaction and bugs. We find the exact same use of containment barriers in the scene that follows, with the extra touch of the military personnel pushing then killing Joel if players venture too far. Inside closed spaces, most games generally use windows, which we’ll see in The Last of Us later.
The arrival at the checkpoint is a textbook example of how to center player attention with a dynamic element. On this crossroad, the first semi open area in the game, players may very well be tempted to go either way, but the arrival of the armored vehicle against the player’s direction, the closure of the gates, Tess's placement near the checkpoint and the yellow sign above all point the player effortlessly to the left instead. Naughty Dog manages to seemingly open the game much wider, while remaining in a narrow exposition corridor.
Another textbook example, and a difficult one to achieve, the quick return tutorial. The narrative scene that introduces it is meaningful as it introduces the Fireflies for the first time in the game, but it also pits the player right against a fence in a position of danger. Just like in the combat tutorial, the necessity to move away from this fight makes it ok to block player controls and require a specific command. Players rarely question this.
As a side note, some of you will have noticed that the main street had not been gated yet in the game, and Naughty Dog made sure it was by adding this little scene of police blocking the street.
When addressing player accessibility and teaching, it's important to make the distinction between the two learning models players can be separated in. The first type, Explorative Exposition, describes players who learn by doing; while the second type Experimentation Exposition describes players who by fear of failing expect to have a maximum amount of information given to them before they try. Designing tutorials for these two types of players is very hard, since their learning methods are diametrically opposed.
Naughty Dog chose here to address both types by designing tutorials for either type and alternate between them. The more complex tutorials, those that either require a huge amount of information given, like weapons for instance (see The Shiv in part 3) or would demand a very expensive and convoluted setting (like this health kit) are designed for the second type of players, stopping the game and giving them everything they need to know before experimenting. The intention of showing the time it takes to heal is well convened here. And to make sure the player actually sees this most important item, Tess gives it away instead of having it placed on a nearby table. Perfect introduction of the mechanic and it reinforces their relationship as no one else would ever have given this for free to Joel.
As much as accessibility is often separated in three stages (exposition as seen above, validation and challenge), players often find these cobbled together. The second stage for instance is largely unnecessary when designing for a core audience that is already very used to these game mechanics and gamepad controls.
Follow a few textbook examples of light placement inside this exposition corridor, with inviting diffused lighting that propel Joel forward. At the end of this sequence, we find the first of many trademark moves by Naughty Dog when Joel jumps down a hole. This kind of transition keeps showing up in Naughty Dog almost invariably to transition into a cinematic mid jump (we’ll see that later in the second combat) or to be used as a loading screen to the next level. It also helps segmenting big levels into smaller pieces where NPCs won’t travel large distances back and forth, limiting bugs.
On the other end of that tunnel comes the first introduction of the “vault over” move, which will be reintroduced at a later point as well. All move tutorials in Naughty Dog games are introduced a number of times in slightly different combinations so players learn by doing more than once. It’s rare enough in games to notice how good they got at it; in reality this entire level is a mixed sequence of tutorials.
Immediately after this “vault over” move, Joel is presented with his first “safe zone” to pick up his weapons. In the rest of the game, this workbench will allow him to upgrade his weapons. The more interesting part is the left hand side “boost and pull” move, which uses very strong warm colors. Once again the use of the yellow signifies interactivity/where to go. All third person games like Tomb Raider, Uncharted, Prince of Persia, etc. use specific colors on their palette to orient the player, particularly at the start of a platforming sequence. The move itself is gated to players having picked Joel’s backpack on the workbench, and the combination of both tutorials in the same room is not by chance, it’s the only move in Joel’s arsenal that can be disabled given it uses a prop and an NPC.
We’ve already seen “jumping in a black hole” as a gate, and lifting this door here is just another example of subtle gating mechanisms used to unload the previous part of a level and load the rest dynamically, so as not to require loading screens, or the strict minimum. It’s now so standard that we’ll soon forget it’s a rather recent addition to the arsenal of level designers, created when dynamic loading became possible with PCs and consoles becoming more powerful.
This leads us into the first puzzle space in the game. Notice the multiple ways to leave this interior space, including the first crouch position to the right. We’ll see the move introduced on the critical path afterwards, but it’s not unusual for Naughty Dog to include such moves before their tutorials are introduced. A few hints give us the direction the player should head in. First the busted up ground is a good tool to shape the ground in the general direction of the gameplay, and make the space visually more interesting (less flat) and more interactive with the player needing to repeat the “vault over” move to get out. Another tool is the direction the crows fly in when leaving the hood of the car. Finally, the red bricks and vines uniformly applied everywhere is a giveaway that the exit is not necessarily straight forward.
Notice the rug over the destroyed wall, accenting the solution to this first puzzle. This tutorial is a great example of puzzle design, where the problem needs to be presented front and center, so that the discovery of the solution leads to a minimal amount of attempts once found. Portal is the most recent game to have perfectly followed that credo. Of course, this is here simplified to its core essence, but the same principle follows in the rest of the "ladder-based" puzzles. A sign that you have a great game mechanic on your hands is the ability to design variants of the same puzzle throughout the entire game. It means it's a deep enough mechanic, and not a gimmick.
After picking up the ladder, Joel enters the very first exploration space where he will be able to pick up game resources. Seen as this type of loot is what the entire game economy is based on, it makes sense to present them exactly in the opposite way to the narrative elements of the rest of the intro. Meaning shrouded in darkness when important narrative beats were placed in brightly lit areas. The lighting in this area is worked so the cabinets are mysterious, so that adventurous players learn this classic challenge-reward combination.
After reaching there and turning around, players can then notice glimmering the very first Firefly Pendant located in the room beyond, with a nice Firefly symbol placed on the wall as a final hint. The placement of that desk in this room is studied to allow that to happen. You can safely assume that this is the easiest of all Firefly Pendants. Having presented the first resources and the first collectible separately is a good move to make sure players understand their different role.
Jumping down (once again, a gate), Joel enters the first spore-infected area in the game. Tess is once again used as justification, by stopping Joel and putting her mask on. Players immediately understand the nature of the threat and that they won’t ever have to put the mask on themselves. The change in lighting and visibility also preface the incoming danger, immediately shown in a safe situation moments after hitting the spores. The relationship between the spores and dead body are made perfectly clear, and this example of narrative design through environment art is perfectly paced.
Just like the doors to Joel’s office in the prologue, here is a great example of using interactive objects to place the character in a specific situation and justify the camera transition to a cinematic. The plank, with its forced interaction, is only here to make players notice you can go through the door by squeezing through. In fact, even the dialogue is designed with that n mind. Once in this position, the camera is entirely scripted. One should always expect a narrative element on the other side of that type of sequence, particularly when entering a brand new space. Using this type of contrived cinematic moves has become a main fixture in Sony titles, noticeably in God of War and Uncharted, and in competing titles such as Tomb Raider. BioShock actually was one of the early titles that always tried to justify camera placements. These sequences also sometimes serve to limit the speed of movement of the player, particularly to help loading times in and out of expensive areas. But there are sometimes ways to include these delays in gameplay itself. For instance some of Elizabeth’s lockpick animations were gated to the loading of the area beyond the gate she had to open. In these cases, conversations between her and Booker would also be timed to the necessary delay.
Once clearing this filing cabinet, a perfect camera takeover to introduce the shooting tutorial. A conveniently placed hurt human (still target) offers the chance for a quick headshot if camera is left untouched. Nearby the ammunition pickup ends this gameplay loop and makes most players come out on top ammo wise. It also offers the game’s first active choice, as are all combats in this game (choice of resources and sometimes tactics). Notice right after this encounter the use of dialogue to justify the next camera takeover and introduce the first combat against infected. The piece of wood falls down just as Tess speaks up, while Joel indicates the need to remain silent. It’s as dynamic an introduction as one can make it and flows superbly.
Please notice the placement of these infected. Them being tutorials, it’s only logical that they are as scripted as they are. The first one plays to the stealth nature of the combat, reinforced by the action and placement of the two other infected. As you can see above on the first floor, they actually are a landmark for players to orient themselves. Most landmarks are used as large objects in the background of a scene, for instance Half-Life 2’s citadel in City 17’s skyline, and in the case of The Last of Us, the hospital Joel and Ellie reach towards the end of the game plays exactly that role, but in tight corridors and encounters, level designers can reverse engineer an NPC as the landmark, and plan their geometry around. In this case carving up the floor just so the infected can be seen below. Near this location, on the bottom floor and the top floor, two exploration spaces that make good use of this gameplay loop (challenge-reward) offering loot just after clearing the combat.
Once again outside, this seemingly uninteresting transition area between the combat tutorial and the upcoming puzzle is made interesting by the basketball hoop that provides a clear sense of direction to the immediate space, and the busted up concrete perpendicular to the court adds a layer of depth to an otherwise flat surface. Notice once again the color yellow used in Mel’s Home Hardware store sign, and its placement over the exit.
Next up is the second "ladder-based" puzzle space that follows the basic rules of great puzzle design. First the exit is presented to the player in the same frame as the problem, and the solution once found (“aha! moment”) only takes one try to complete. Notice how the blue tarp provides a good visual clue in this tutorial as to where the solution is, just like the rug in the first case.
Leaving the puzzle area that shows that the best game mechanics can be used in multiple variations, the same yellow color is brought by lighting through the window. Around the corner, a little reminder about exploration, with a health pickup dropped on the far end of the ladder.
Down yet another gate and Joel now follows Tess through a back alley. This otherwise uneventful place sees the addition of yet another reminder of the “vault over” tutorial, as another way to require a button press from the player and keep him/her engaged. This however no longer requires the UI indication on screen.
Just around the corner lies the second Firefly Pendant. “Hidden in plain sight” is a good way to introduce a second collectible, after having given the first one essentially for free. This one perched in the trees, and the puzzle before it tease the elevation changes of gameplay taught in the subsequent combats. You’ll notice the LD work that went in creating the blockage under which Joel must crawl, which reveals through its branches the glimmering Firefly Pendant.
Forcing the player to continue through a building serves multiple purposes. The first, and smallest is it helps justify the placement of gun ammo on the table, as opposed to having it just lying there on the streets. The second, the door that Joel closes behind him, is yet another gate for the upcoming NPC – heavy survivors camp, which can even be loaded during the third and final purpose, introducing a small child in a narrative sequence with Tess. These windows here give just the right amount of light in and allow the heavy contrast between the two areas to have the animation read a lot better. This room could have been there simply for optimization purposes, but Naughty Dog managed to turn it into a whole lot more.
The survivors’ camp is another gameplay loop closing in on itself. After the initial exploration and learning came the tension of the spores and the challenges of the first fight and puzzle, the camp is a narrative reward for having made it this far, and a chance to pick up another two collectibles. However as it’s not the end goal of the level, tension should still be a constant theme, hence the more and more violent scenes one after the other, that also introduce the upcoming fight with humans. Notice the little girl playing with her stuffed bear in the far corner. She and the little boy earlier are nice ways to feature children in action games where rules dictate that no human child should ever be killed on screen. Emphasis on human; children that do get hurt are often already dead, possessed or otherwise sick (School bus in Prey, Little Sisters in BioShock, etc.)

Intro Level 1st scene In typical movie fashion, the game starts with an exposition scene which establishes the bond between Joel and his daughter Sarah. Here the watch plays a type of backward MacGuffin (http://en.wikipedia.org/wiki/MacGuffin), which movie fans will be familiar with. A term made popular by Alfred Hitchcock, this initial narrative element will keep showing up in multiple scenes in the game to move the scenario forward and link back to the initial bond Joel had with his daughter. Many other items in this game, which we’ll see exposed in Sarah’s room play the same role. It’s important to note that this game doesn’t use forward MacGuffins, instead relying on the early experience players have with Joel in the intro levels to help them relate to Joel in the later parts of the game, when he faces adversity from the other main characters in the game. This type of catalyst is sometimes linked to gameplay in some games, but not here. For instance, in a quest, looking to get somewhere or obtain something but never managing to. In BioShock Infinite, Elizabeth keeps trying to go to Paris, but never quite goes there in the main game.
Gameplay Sarah goes to bed, only to be woken up by her Uncle Tommy’s phone call. The initial frame of Sarah getting up is a textbook example of player exposition. Using the mirror on the wall, Naughty Dog adds depth to the room, and presents Sarah as a playable character from both front and back. The color of the lamp shade also leaves nothing to chance. Using a warm color near her beloved items reinforces the comfort of her nest (bed) and contrasts heavily with the cold blue of the night in the mirror. These items on the wall, much like the watch earlier, play a narrative role in the rest of the game as tools to drive the scenario forward between Ellie and Joel.
Sound wise, Naughty Dog made a classic choice not to add any music and simply build tension with environment sounds in the background. It plays great and helps focus the attention on the initial reveals. In the room, the placement of the birthday card ties the opening scene with this scene the following morning and introduces the “triangle” button as the “hand interaction” one in the game (pick up item, open door, etc).
At this point in the game, the player still does not quite know what to do, despite having played for a few minutes already. This guidance is given very clearly in a single word, right outside Sarah’s bedroom, as she yells “Dad?”. Perfect example of narrative design coupled with level design, that tells the player his/her immediate goal, and invites him/her to check out every single door, increasing the chances for maximum exposition of every theme in this intro level.
With the goal now firmly established, the placement of the door straight ahead, too obvious, makes that room a natural space for continued exploration of the game’s themes, as opposed to a significant room. It comes as no surprise to find inside that room just one piece of content. The placement of the only light source in this room, obvious as it is, reminds us that lighting is one of the most straightforward tools to guide players.
Joel’s bedroom After leaving this bathroom, players are naturally directed towards Joel’s bedroom thanks to the window, extra light placed in front of it, and the barely open bedroom door. The sound of the TV is an ideal guidance tool, suggested instead of shown. This bedroom also offers the chance to see the gameplay loop closed for the first time. The Last of Us’ gameplay loop is always a variant on four themes: Exploration, Tension, Challenge, Reward, Return to Exploration. With the initial exploration started in Sarah’s room and the tension of having to find her dad, this room introduces the simplest of challenges – opening the door and following the gameplay instructions (L3) – which ends with an immediate reward of seeing the explosion in the distance. Finally, Sarah’s “Daaad?” closes the loop and makes players return to their exploration phase. Gameplay loops can express themselves over varying lengths. Second to second, minute to minute, hour to hour.
Returning to the hallway, a few classic LD rules can be seen in the same frame. The placement of the door allows players to face the staircase in the right direction, and the placement of the lamp at the bottom automatically invites players to go down. Notice its actual placement. While most times placing a light source away from a player’s immediate field of view increases its attraction, this one is placed to the right in plain sight of the player.
Once at the bottom of the stairs, the window introduces a new narrative element, in the form of police cars. Notice that the cars are driving in the same direction as the player needs to move. This is yet another good tool to guide players subconsciously. If the lamp at the bottom of the stairs had been placed to the left, and away from the player, he/she would have likely turned the camera towards it and away from the windows, negating the introduction of the police cars. That’s why this light source was better left in the player’s field of view.
Players naturally progress and now face this door to the garden, this time with a light source hidden beyond the playable space which naturally increases the mystery and tension in the scene. Just like upstairs in Joel’s bedroom with the TV, the dog barking here increases tension and attracts players forward.
Once players reach the window, Naughty Dog doesn’t fall for the cliché of having an infected appear in the garden, and plays with players expectations instead interrupting the sequence with Joel’s phone. Doing so, “L3” is introduced again this time on the player’s critical path to make sure this mechanic is understood by all players.
The placement of the phone to the right of the door is also no accident. It makes players move further away and to the other side of the living room from the office, where players are now supposed to go. This forces players to go by the garden window a second time and the use of the phone has forced the player’s immediate attention of the window to be erased. This perfect set up was necessary to create an element of surprise for the second traversal of the living room.
Narrative scene and transition A sign of truly great narrative games is the justification of every single camera takeover by placing the played character in a situation that allows for a smooth transition. Here, that’s the only reason this half open door is placed here. Since it’s already half open, like Joel’s bedroom door, there is no “triangle” interaction required. The goal of this door is to justify the exact position of Sarah in her animated entrance into the room, therefore the position of the camera, to allow for a smooth take over for the rest of the cinematic and the entrance and reveal of Joel, the very first in the game.
While the entire scene could have played out inside Joel’s office, Naughty Dog chose to have Sarah and Joel leave the office half way through, so as to cut back the length of the walk to the exit door and outside to the car. This allowed them to shave off a few seconds of otherwise boring content and make the action denser. Uncle Tommy’s introduction is pretty hectic with the rapid movements and a lot of information handed to the player, so to reinforce his presentation, Naughty Dog chose to have him turn towards the player once inside the car.
The Last of Us, as many narrative games, presents choices to the player. They come in two types, active and inactive. Active choices are generally self-explanatory and are not even presented as such in games. For instance, play style (stealth or action) influences the outcome of fights, but they can also come in the form of a single button press, which usually destroys immersion in a world, and breaks the fourth wall. Inactive choices on the other hand play with morals and psychology between players and the characters they play. Here we see the first glimpse of the troublesome relationship to come between Joel and Ellie, in the eyes of her daughter Sarah who wishes that the car had stopped to help the stranded survivors. This makes players ask themselves where they would stand, and take sides with the future protagonists.
The accident serves here as a transition and justifies leaving the car behind. The timing of that sequence is probably not purely by chance. First Naughty Dog had illustrated all the themes they could from inside the car, and second the attention span of test players was probably waning beyond that point. Notice however the subtle and progressive introduction of infected in the world. The first one, inside Joel’s office comes in when they may yet be taken for humans, and as an element of a cinematic, it offers no challenge to the player. The second, in this car sequence, attacked other survivors and when posing an immediate threat to Sarah, was stopped by Tommy driving away. The third, much closer view comes in as a direct consequence of the car crash. These three progressive introductions of the game’s main antagonist are a textbook example of exposition that allows players to fully grasp the concept of the infected before having to deal with them. Many games fail to present enemies that way, instead relying on one-shot cinematics with poorly explained antics and backstory. The fact these enemies can’t talk and explain themselves pushed Naughty Dog to work them this way into the game, to great effect.
Combat Tutorial First introduction of the « Square » button for combat. As a rule, tutorials are better introduced when players attention span can be solely directed at the mechanic in question. Here, the tension resulting from the car accident and the sight of the infected nearby focuses the player’s attention on the tutorial for maximum effectiveness. Instead of breaking the immersion of the scene, this tutorial actually flows inside it, and players never question it. Naughty Dog’s choice for minimal UI invasion on the screen really pays off here.
Chase sequence Introducing Joel for the first time as a playable character (and the main protagonist) in the middle of a stressful situation could have been a risky proposal, which Naughty Dog managed to make work by taking away all combat (automatic death if caught by infected and gun given away to Tommy). Sarah, who would have trailed behind and become a center of attention for players is reunited with her dad after getting hurt in the accident. All of these moves act as perfect justification to have players only ever care about their own character. The only action required of the player is to dodge pedestrians, which is exactly the best activity to learn to control a brand new character. The use of a car that crashes into the gas station is a bit of a cliché by now, but remains a very strong justification for sending the player to the right, and have a couple invisible walls across the other streets. It remains better than a simple static object across the street and infinitely better than nothing at all.
The firemen truck across the street serves both as justification for the fire raging in the building next door, and as a way to direct the player to the car crash about to block the street off. This second instance however occurs much closer to the player, increasing tension further, and culminating with stopping in front of the theater beyond. This “three strikes” approach to game design is rampant through most games these days, and certainly The Last of Us, for instance during the combat tutorial (three square button presses to leave the car) and is a sort of golden number first generalized by Nintendo.
The use of audio after the third street blockage is mandatory given the exit is not readily apparent within a 45 degree field of view on either side of the theater. In third person games, presenting exits within this 90 degree angle is generally considered a safe choice to have players flow, on consoles at least where the FOV is usually limited more than on PC games. For instance, this was the rule we followed when designing Prince of Persia in 2008.
In the alley and through to the other side, great use if not subtle of lighting to direct players to the left, and first use of the yellow color on all directional and interactive hints, which we’ll see later in the first level. We’ll find the same use for the ambulance down below, which strong red lights contrast easily with the night, and even the wind indicating the sense of direction. The headlights serve as guidance too of course, much like the hurt survivor on the ground.

Pampers reacted to FMPONE for an article, Making a Map: CS_Museum
The creation of a map begins with an idea.
In the case of my most recent project, CS_MUSEUM, I needed a basic look which would resonate with players immediately. The thought of making a Museum worked… it was a simple one, it had been done before (although this wouldn't be a re-make of the classic DE_MUSEUM by Theropod-X). Players would understand a Museum environment, and it fit in the Counter-Strike world.
Forming a map’s final look is complicated, though, and requires thought about what kind of architecture, colors, and lighting you – an artist or level designer – will pursue.
I’d been playing a lot of the classic map CS_OFFICE, which requires players to storm into close quarters for indoor combat. That kind of game-play is fast and unforgiving, I dig the kind of matches it creates. CS_ASSAULT, I shouldn't forget to mention, is another great map that defines the "siege a building and rescue the hostages" genre. Actually, most of my favorite CS_ maps including Militia also foster similarly dynamic games that challenge you to be sneaky but also use brute force to accomplish your objectives.
So, I set out to make a hostage rescue map like Office and its kin. Studying prior maps is a good way to establish what works well, and avoid what doesn't.
One other map that influenced my thinking: CS_CABARET by Alex Roycewicz.
Cabaret is a great map — it got Alex a job at Infinity Ward long prior to that illustrious studio being kicked in the nuts super hard by mega-publisher-that-will-remain-unnamed.
It was from Cabaret that I basically ripped off the front of Museum... with a few changes.
In truth, though, I had some bones to pick with Cabaret.
Unforgivably, there was no sense of vertical space on the outside of the strip club. Also, while the building exterior is convincingly rendered, the overall space is too geometric: everything seems to face the viewer on an imaginary grid, which is no coincidence, that’s how the Hammer editor encourages people to make maps.
Cabaret on the grid:
Museum screws the grid:
If this analysis is starting to sound harsh, it’s worth noting that Cabaret was one of the best custom maps of its time, so this is more of a modern critique of older game art.
As is often the case with older game art, most of the limitations or flaws obvious to modern eyes were not the creator’s fault: Hammer around the era of Counter-Strike: Source (for which Cabaret was made) did not have all the technology I made use of for Museum. One example is “instances” (the pale green elements in the overview above) which are brushwork more akin to models than typical brushwork, because they can be rotated “off the grid” and not cause compilation problems normally associated with brushwork which is off the grid. Thanks to instances, I was able to rotate buildings to achieve a more natural, organic look — such as this bridge:
In order to actually create the specific buildings in the map, concept art and photographic references were key.
Here's an explanation of the Museum front.
The most pertinent point to make here is the difficulty of knowing when a photographic reference is valuable, and what makes it valuable. To explain this in extreme detail might be delving into an area of “talent”... or it might be worth the subsequent explanation I’ll now provide. In any case, this should explain my process.
The best photographic references share one crucial element: readability. Complex buildings such as the one above, if they are to be useful for our purposes, must be able to be broken down into clean, clear shapes. I was confident using the logic explored in the line-work above (I did this part in my head), that the building could be broken down and translated successfully.
The building begins to take shape, with the red lines becoming props. When using Hammer, what becomes a prop and what remains brushwork largely comes down to the default assets you have to work with.
Talented 3D modelers have their choice of creating new content, but their time is precious and each art asset is an investment, so even then it’s best to think about default materials and their role in your work.
This lovely picture inspired the placement of the obelisks, and secondarily the pond on the right of the Museum.
Using concept art and photos in conjunction with my imagination, I had derived a basic visual identity for the map:
Obvious reference: the Brooklyn bridge; non-obvious reference, this lovely piece from Deviant Art:
Making a map is about looking at the world around you and seeing something inspiring enough to create a desire within you to render it and mold it for your own purposes.
By this point in time you may be shouting IT’S A MAP – TALK ABOUT THE GAME-PLAY, TALK ABOUT THE GREY-BOXING YOU FOOL! …and, while the playability of Museum ended up better than I could have imagined, there is no glory in my process for that particular aspect of the map. Uh oh, he’s gonna say he didn’t grey-box it, isn’t he…
First, the excuses: previously, I'd recreated the Natural Selection 1 map NS_VEIL for NS2, based solely upon my own literal eyeballing of the geometry, without any scale-guide, in a different editor and a different unit system. To put all that gibberish into other words, I’d done nothing for two months other than study the rigid grey-boxery of another mapper, then spent another 10 months making that geometry fit into the context of a new game and engine. I’d worked with fastidiously organized layers, done everything by the book, guv, I swear.
While important for a commercial product, that experience had temporarily tired me somewhat of the (smarter) formalistic approach. As a result, no substantial grey-boxing would take place for Museum. Manic energy took the place of “rules” and “common sense”:
Basically, I was creating stuff I thought looked cool, not getting terribly fussed about what direction it would all head. This is the way newbie mappers work, or idiots, or both… but it can be done if you’re smart about it.
Certain things can’t be bullshitted around, though: your map must be in proper proportion to the players, and it must maintain sensible sight-lines considering the game type. You need to know the game you’re making the map for, and know it well.
So working free-form has its advantages, creating a whimsical sense of liberation in the budding mapper. It comes at big costs to him, though, in other aspects. This open doorway, and the entire route it signified, never made it into the final product. People have noticed its conspicuous absence, however, to the point that it may make it's return soon enough.
Working toward a result, with certain restraints in mind, but willing to cut: my method for Museum.
Mistakes were made. Certain areas violated basic good-practice principles, such as this one:
I call this piece of modern art “Abstract Red Light Number 48.” So… this elevator shaft was painful for a few reasons: too noisy inside, not clear enough about what it was meant to be, and the idea of it having a purpose seemed impossible given the amount of crap stuffed into the scene.
I believe I settled on a better, cleaner result:
Which was based off of this reference:
This shipping area was another idea that got cut (considering that it was over-dark, this was not too sad):
Everything else seemed to go swimmingly, however:
My biggest advantage when working with these references is my ability — and perhaps your ability as well — to discern from them what elements are most relevant and work best geometrically. These judgements influence what makes it into the map. While you may be able to follow a similar protocol by examining the pictures, you would be doing so in hindsight; it was quite necessary during this project for me to be able to sift through literally thousands of images in order to find those which, at first glance, provided the requisite inspiration.
References must be clean, they must convey a certain tone, and the architecture they illustrate must be plausible among the rest of the map geometry. This process of looking through seemingly endless references is a task which must be begun anew with every new map.
Back on topic: a month or two after starting out on the map, I recruited a talented 2D artist named penE who had a style congruent with mine. With his help, rooms like this began to form their own identity:
The map began to develop a sense of humor. We based the name of the museum on HURG — Hero of MapCore! (Don't ask.)
PenE brought his full enthusiasm to the project, getting almost all of his work done in a month or so, a rapid pace which would be a major motivator for me while I was working with (read: waging war against) the Hammer editor.
Here is a sample of penE's work for the map:
Nevertheless, the map did seem to require more art…
I had envisioned a T-Rex in the above room, and had designed the room around that eventuality. I was concerned that such a 3D model might not fit well (it’s a relatively cramped room), or might not be appropriate looking, but I put out a call for a talented 3D artist.
3Dnj answered that call with a stunning T-Rex model based on square-shaped geometric restraints. I basically stacked a bunch of cubes on top of one another and said, “OK now make me a T-Rex that fits inside the squares.” Seems hopeless, right? Thankfully, Valentin, as 3Dnj is known, e-mailed me this bad boy:
Owns right? Imagine waking up and seeing that first image of the T-Rex with that brilliant sheen, I was ecstatic.
At that point I realized I’d found a true collaborator and not just a “prop guy”. Valentin would go on to help me optimize the map, and reform a lot of my map geometry into more sensible models. Here’s how crazy things had gotten:
Hammer is unlike a modeling program in that it is “brush-based”, and things that are not literally six-sided cubes give the editor trouble. Trying to create an interesting shape out of a single brush? Take a hike.
So it’s obvious why a more extensive collaboration was needed: it was never going to be realistic to proceed in such a manner and expect an optimized result which would (ugh) compile. Hence, the logic of making a map which looks the way Cabaret does, unfortunately all the same limitations applied more or less in 2012, with just a few exceptions like instances.
So there were technical challenges, but four months on, most of the major lessons of the map were learned and my vision for the map was realized almost exactly as it existed in my brain.
My workflow can be best summarized as: find a fitting photographic reference, get a basic interpretation of the geometry into the game, and then polish with aesthetics and navigation in mind (lead players with lights and colors).
Rather than attempt to convince you I pursued the traditional level-design approach of iterating a grey-box, I hope this document serves to explain the approach I actually took: a risky and improvisational one that I know I’m lucky was successful. It’s good to state how lucky: a layout that emerged without argument, finding two brilliant collaborators with a lot of faith in the project, etc. Hopefully anyone looking to duplicate my exact method will be given pause, but at the end of the day there will always be logic in working hard and having a well-formed mental image of your goal.
As for Museum, I can promise you one thing: if you load up the map, and I hope you will, I think you will enjoy it. (If only for the giant, motherfucking Tyrannosaurus Rex.)
Thanks for reading.
Pampers reacted to Froyok for an article, Technical breakdown: Assassin's Creed II
The following breakdown is based on my own guesses and how I understand the game from the textures and meshes I have watched. I can't tell you exactly if I'm right or wrong since I'm not a developer of the game. However, I believe I'm rational enough to think that most of what I say is close to what the developers have done. The purpose of this breakdown is educational and the work presented here belongs to its respective authors.
Anvil engine The Anvil Engine is a proprietary game engine used by Ubisoft's game projects for a few years now (the first game using it came out in 2007). We can call the Anvil Engine a next-gen engine since games for the previous console generation (like the Playstation 2) were using the Jade Engine at Ubisoft. The first project using this engine was the first Assassin's Creed game. Its initial engine name was Scimitar (before the release of the first game). Today, eight games are using this engine.
The engine has since been updated with Assassin's creed III under the name 'AnvilNext'. Mostly to support the new game challenges and configurations that we have today and probably to be ready with the future game consoles coming along.
Atlas and batching As with every open world and/or huge city, you have to deal with a very high number of resources. Mostly to keep the player in a fresh world and avoid repetitions. Games over the years have used various techniques to get past this problem. One of them is to reuse any resources that you have created. Creating a texture for only one object in this type of environment can be a problem in term of memory footprint. So reusing a texture will allow you to keep you memory low in size. Pretty obvious, however it's a hard balance that you have to deal with: diversity versus quantity.
The size of the memory is not the only problem that you will meet; the number of drawcalls is also very important. As a reminder, a drawcall is a call to the API (the functions of the GPU to draw a set of primitives). For each frame that you render, you have a certain number of drawcalls. Each time you call the API to draw something it takes a given time, regardless of what you want to draw. So you want to be sure to reduce these calls to avoid any loss of performance (taking too much time to draw a frame will reduce your number of frames per second).
Each time you change a mesh for a new one you will create a new drawcall, because for the engine it's not the same geometry. This rule applies for the shaders too. If you change the shader, you don't render the same thing, so you have to change the way you render it. This means a new API call.
A common solution to this is to batch your calls. 'Batching' means to group some meshes together before calling the API to draw them. This is why it takes less time to render a big mesh than multiple small meshes. How to batch these meshes if chosen by the engine, there is no best rule for this and it depends a lot of what you want to draw. In the case of the Anvil engine, you are focused on drawing large and open spaces. The best way to improve the performance in this case is probably to batch per shader. So each geometry using the same shader will be sent together to be rendered. This way, reusing textures will allow you to batch a lot of things and gain a lot of time.
So using atlas textures (multiple textures merged as one) will be a great benefit: you will reduce your memory footprint and you will use only one shader for multiple objects showing different things. Assassin's Creed II uses this system a lot for the environment and the characters. Since we evolve in cities, some houses are often similar, it is logical to find the same design multiple times. Which means that reusing a texture would not shock the player. It will even help for the visual consistency of the level. However, I believe that the engine was not perfect and due to some performance problems (maybe because of the dynamic lighting) they limited the number of textures. In Venice for example, you have an average of 1500/2000 textures in memory (including everything: sky, water, normal maps, shadows, characters and so on).
What do the textures look like exactly? In this game, textures for the walls are often around 512 x 512 pixels. Details, ornaments, water use 256 x 256 pixels most of the time. For example, the roof texture is only 256 x 256, but the tilling is so well made that it doesn't gene at all.
However, these textures being very tiny, the developers used vertex painting to blend details and break the repetition. Since there are almost no specular reflections in the game (probably to strengthen the feeling of the walls are made of bricks and dirt) the vertex painting masks are stored in the alpha channel of the diffuse texture. As you can see in the second screenshot below, the alpha mask uses very defined greyscales, probably because they separate each level of grey as a separate filter.
The textures are very bright, and we feel that in-game: the overall lighting is itself very luminous.
Levels of details Dealing with an open world means dealing with a very long view distance. Therefore, the farther you see, the more you need to draw. Unfortunately you are limited by the hardware (especially on consoles) and you will have to use some LODs (level of detail). The developers have chosen to let the LODs 'pop'; this means no blending transitions between them, which is visually ugly since you notice the change.
The environment collisions are dissociated from the visuals mesh. Probably because you can more quickly hide/disable the collisions of the environment since they are not visually displayed on the screen. This explains why forcing the LODs of the environment allows you to... climb the void!
On the PC version, you can increase the minimum distance for when the environment starts to blend (which is something like 40/50 meters if you blend at the furthest possible distance). It's also interesting to note that some props like barrels, crates and other little things are independent of the global LOD distance. It seems that some props are linked to the LOD of the building mostly because they are at the roof level, while props in the street have their own blend distance.
Characters Pedestrians in Assassin's Creed are based on modular characters. The developers use a set of heads which are combined with hands and different clothes. While the hand and heads have their own details and colours, the clothes are just a totally grey shared texture (except for the letter) and coloured in the shader to add variety in the game. They also add a detail texture to break the linearity of the clothes and bring up some fine details. Characters have also their own LODs.
During a presentation at GDC 2008 about the first Assassin's Creed, Francois Levesque (a technical director on the game) explained their pipeline to produce a lot of different characters without losing too much time. They used a base head which blends to fit to the high-res character. This way they automatically get the LOD mesh at the same time since the meshes always shared the same topology. The only update to do was for the position of the bones on the top of the vertex to keep their skin deformation.
Since meshes and UVs are similar, it's easier to manage and create a crowd dynamically. So there are maybe 5–10 different clothes and then the game dynamically creates a character to add it in the game scene. In the first Assassin's Creed, characters had 2 LODs, which meant 3 meshes per character. In Assassin's Creed II it's the same thing. However it seems that the clothes and the head don't blend at the same time. Probably because they don't have the same space occupied on the screen. So the heads go to their first LOD mesh sooner.
You can see some examples on zBrushCentral with the base mesh topology and also the topology of some bodies used by the game.
Lighting The Anvil engine is an engine developed to mostly show open environments. With the development on this second opus, they wanted to add a day-and-night cycle. To achieve this they naturally chose the cascaded shadow maps technique (more exactly, Parallel-Split Shadow Maps as described in a GameDev.net forum thread) which even today is the best way to draw a unified shadow on such big environments.
There is no Global illumination at all, it's mostly only a main directional light (the Sun) combined with an ambient colour which evolves during the day. Some interiors like the tombs present localised point lights; there are also some point lights which are enabled during the night.
However, regarding the performance, they were obliged to use a very low resolution and a blend distance. This explains why you see a lot of blurred pixels on the ground/walls for the shadow. This is also why you so clearly see the blending of the shadow from one level to another.
Some shaders use the Fresnel term to enhance the looking of the character clothes a bit, but most of the time they simply use direct lighting without complex shaders (again, because it was very expensive). There is no fake sub-surface scattering (SSS) for the characters, even during the cinematics. The SSS only comes in with Assassin's Creed: Revelations and will be improved for Assassin's Creed III.
Conclusion Assassin's Creed II was a really good improvement compared to the first game, however it looks like the engine faced a lot of new constraints which were not totally well handled. The way the LODs appear and the nice but still limited quality of the lighting are good examples of that. Even on modern computers today the game gets some slow-down in certain places.
The engine was improved for the next game iterations and increased the amount of details and the quality of its lighting to finally show beautiful cities as we can see in Assassin's Creed III today.
Pampers reacted to Thrik for an article, Interview with Jean-Paul Jarreau, Black Mesa level designer
Tell us a little about yourself. Where do you live, and what's your day job? Oh man. I unfortunately live in Rochester NY (no its not driving distance from NYC) and am currently unemployed. I graduated college with a degree in Photography and a minor in Philosophy in 2011 and worked for my step father's company until july of this last summer. So I currently spend all my time working on levels and photography, I honestly cannot complain right now.
When and why did you decide you wanted to bring worlds to life in 3D? When I was 14 I had a passion — playing games. I loved it, it sparked something inside me and I had no idea what it was, but I liked it. My personality can be pretty analytical at times so naturally I tried to figure out how to make them. I love architecture, buildings and 3D space, so I just went for it. I spent hours and hours in every level editor I could find and I, admittedly, stuck with hammer because it was the easiest to pick up, had the largest support and the biggest community. I've been with it since. That's what, 9 years? 9 years of blue screens and move_rope causing crashes straight to the desktop — it's a love–hate relationship.
How did you get involved with Black Mesa? This is funny considering the level of amateur crap I have made. I applied to Black Mesa back in 2004/2005 by sending a VMF to the founder of Black Mesa (Jon) of my recreation of the first Power Up level. It was a mess and ugly as sin. I had quite literally no idea what I was doing, but it was satisfying to create, so I kept with it. I clearly remember Jon's words: "It looks, eh, amateurish". So, I spent the next few weeks refining my work and I applied a few other times. I eventually got on the team and I started work from there. I remember a good friend of mine, Daniel Junek, was already on the team and when I loaded up the private developer forums and saw his orange map layout of the blast pit silo, immediately knew I was going to be on the team for a long ass time — I saw what COULD be Black Mesa and was instantly inspired.
Funny story: I always considered Daniel's work (he did Blast Pit) to be godlike, it was just incredible, I had never seen anything of such quality and ridiculous planning and care. I have this habit of comparing anything I do to the current best work in the world so I know how to improve myself and I considered Daniel's work to be the best in the world. So, naturally, I compared my work to Daniel's and for years it never even compared, but I was slowly getting there. So, a few months ago I, slightly buzzed, messaged Daniel on steam and came to realize he did the same thing with my work this entire time.
I joined the team and looked at what was available to work on and I, of course, had to pick Lambda Core. I had no idea what I was doing and some of the early parts of Lambda Core show that.
What was it like getting to reimagine the world that kicked off many MapCore members' interest in level design? Oh wow I never thought of it this way. Want to hear something hilarious? Before getting on the Black Mesa team I had never played Half-Life before aside from one or two killbox matches on a friends computer.
But as for re-imagining a world that so many hold dear? Its a difficult process, at least for me. I wanted to strike people on an emotional level with my work, I wanted people to see certain things I made and say "Holy shit, this is amazing", and while I don't know if I have accomplished that or not, I do know that getting there was an intense process.
I remember loading up a Lambda Core map and thinking to myself, "What makes this interesting? What makes this bad? What makes this fun? What makes this area instantly recognizable? How do I create something in the present that completely awed those in the past? It was honestly tough in certain parts and I can remember re-doing sooooo many parts of the game because I personally thought it didn't hold up to any creative scrutiny.
Were you often tempted to take a whole new approach to parts of the game? How did you find the right balance of old and new? This is a good question and I bet some die hard Half-Life fans still think we screwed up parts of the game haha. For me it was mostly taking a look at the original and what it tried to accomplish and improving on that. Sometimes certain areas didn't even need improvement, it just needed refinement, an extra level of polish to really take home its intended goal. When there was a controversy over what should be done in the game, we would just look at the 'numbers'. Did a majority of Half-Life players like this certain area? If not just scrap it and try again but be sure to retain the original's emotional impact on the player.
Did it ever feel like Black Mesa might never make it? Was your motivation affected? More than you can ever imagine. We worked on it for about 9 years remember! Honestly? It probably felt like we weren't going to make a release more than we were going to make a release. There were periods of inactivity on our developer forums for months at a time. We all have personal lives to attend to and sometimes it would be a perfect storm of events where no one would work on anything for extended periods of time. Then, out of nowhere, something would happen and everyone would get sparked and jump right back in and get loads of work done for months. Rinse and repeat.
In the SUPER early stages of development there was a point where we didn't even have a coder for 2 years. You can only imagine how incentive was on the team at that point.
There's still a significant portion of Black Mesa yet to be completed. Will it be purely new material when the remainder is released, or are you revisiting and/or expanding existing material? I will answer with a simple work-in-progress screenshot of something I am working on and nothing else:
What do you think is a stand-out part of Black Mesa? I have actually never thought about this! But the FIRST thing that jumped into my head is when you first enter the turn-table room in Power Up. You witness an intense fight between a Gargantua and a few human grunts. It's incredible because of the collaborative effort that went into it without a single f**king hitch. It's like it was done by one person! Let me explain:
You enter a beautifully themed section of the facility created by Daniel Junek You witness well crafted animation by Nate of the Garg getting blasted by a human grunt and consequently falling into and breaking the concrete wall near him. The Garg was made by Chris The surrounding textures are made by Mark The dead human grunt bodies turning into scorched corpses, the flame effects, and the Garg behavior was done by Paul and Mark All the sound was done by Joel Look at that! It's the personal work and vision of a team of people all together forming a unified and impressive quality of interactive work. It wouldn't even be possible to create something that well done by one person.
Now you may say "Hey, thats how all games are made." But, its a little different when you are creating something of this size and scope and all you have to communicate with your co-workers is Skype and a forum. There were a lot of times when I would be making a gesture with my hand or something while trying to describe the way I want a prop or texture to look. That was frustrating.
You do a lot of multiplayer level design in addition to your single-player work. Which do you prefer? Single player is telling a story and using the environment to make playing the story fun and visually interesting while guiding the player through a struggle. If you can hold a player's attention and feed them the facts then you are good to go. Multiplayer is about cohesive design and fun welding itself into one entity and that can be difficult at times. Honestly I probably prefer the multiplayer work because of repetition. You know players will be running around your environments thousands of times which will eventually lead to an appreciation for the map on tiers usually only seen by the actual level designer. That is a double edge sword though.
Briefly, what's your general workflow for putting a level together? LAYOUT, LAYOUT, LAYOUT. I try to get simplistic layout for a map that is fun and cohesive before doing anything else. Why do you play a video game? Because it's fun, and as a level designer, that fun can be directly proportional to your quality of work. You are almost like a spokesperson of your entire team's work and I love it. I mean I could tell you about all my thought processes while I work but that isn't as fun. But, I usually tend to think of ideas in a 3D space, so I never really draw layouts, I usually just throw some brushes around to get my idea out of my head and see what can be made of it before I attempt any sort of real layout. A lot of my past ideas failed even before getting to the layout stage, so that is good (I think).
Which bit of the process is your favourite? That part in a map's life right as you know everything is fun and you get to unleash your thematic ideas you had been planning in your head while working on the gameplay and layout.
And your least favourite? Any sort of tedious mind numbing repetition is annoying. Or when you spend a long ass time solving a problem in your level only to have it come out like crap but its 5am and you have to go to sleep knowing what you just created is terrible. That's no fun for anyone.
What's the hardest problem you've encountered while mapping? Writers block can apply to anything really. There were times where I would just stare blankly at a map for hours not knowing what to do. Recently though? I cant stop with my ideas, it's great. I'm trying to ride that wave for a little.
Also, scrapping something you have put a massive amount of effort into can be disheartening but it has to happen sometimes. But what essentially is anything creative? It's the formation of an idea while hiding your influences. Sometimes these ideas need to go through an emotional struggle before work can continue.
Which piece of level design are you most proud of? To date, my Black Mesa magnum opus is most definitely the final Lambda Core teleporter and its prior lower reactors. Fun fact I thought some designers might appreciate: the entire Lambda Core reactor and teleporter actually lines up like an actual facility if you copy all the maps into one file and place them correctly.
More recently? It's my map cp_imbricatus for Team Fortress 2. I have a feeling that the map will fundamentally change the way a good three-control-point attack/defend map should play.
In addition to level design, you're an accomplished photographer. How did that begin? Accomplished? Oh you. Thanks, you.
Here is a story I have never really told anyone haha. I was an idiot in high school, I mean who wasn't? But when it came time to apply for colleges, I just straight up didn't make the cut. I applied to stupid high reach schools and nothing else, I think I even applied to the wrong program in a few schools. Needless to say, I didn't get in anywhere and I panicked. My mother had some connections at Rochester Institute of Technology and randomly one day called me while I was out and asked me a few questions:
She said, "I got you into RIT and their photo program doesnt require a portfolio, which would you like to do? Fine art, photojournalism, advertising or biomedical photography?" I got lucky and I knew it. I wound up graduating with a bachelors of fine art in advertising photography. Crazy.
A lot of your photos are taken in very challenging conditions, such as live music performances. What skills and equipment do you employ to get such great results? Simplicity is key. Both visually and philosophically.
You must look at every situation like you are the one viewing the content with no prior context as to what is going on. Do you want to portray a story? Do you want to create something purely for its visual content? What's your end goal? I could honestly talk about this for hours.
I currently only use a Canon 5D Mark 3 and the only lens you ever need — a prime 35mm f/1.4. A good photographer with a bad camera is going to make better pictures than a bad photographer with a good camera. I also adhere myself to a lot of personal restrictions (in level design as well). An example being I never crop any of my images, I always thought it was best to just leave it straight out of camera. I do Photoshop my images, but I don't crop them. (Note: if you are a client that hired me as a photographer, I will do anything you want to the images if you request it. These rules usually only apply to personal work.)
Keep an eye out on my Tumblr for some new photography coming up soon.
Do you find that your photography skills bleed into your level design? For example, when composing scenes? Absolutely! And it works both ways too, photography helps my level design and level design helps my photography. Lighting plays a more important role in both than most even think. I am just lucky to have experience in both.
I don't want to toot my own horn here but look at the lighting in some of the reactor areas in Lambda Core. It got to the point where I set 50% and 100% falloff distances with a hard cut-off for the yellow lights surrounding the central cylinder so the centre reactor would ominously glow yellow without casting any mood changing light onto the surrounding geometry. Does that level of detail pay off in the end? I don't know but I hope so.
What games would you say have inspired you the most? I have never thought about this before but here is a list of the first games I can think of to inspire me:
Ocarina of Time: Video game perfection. Majora's Mask: I cannot even put into words the impact this had on me Wind Waker: How do they even make this stuff? It's like they converted crack cocaine into playable form. Half-Life: Was I obligated to say this? This game changed what a first person shooter could be with its incredibly inventive layouts and story telling. Painkiller: The basic first person shooter mechanics perfected and in gory glory too. Incredible environment art to boot as well. Banjo-Tooie: Incredible game design, just incredible. Battlefield 2: The amount of serotonin released in my brain by playing this game should be illegal. Super Mario 64: An amazing sandbox game before that term ruined a lot of modern day games. Far Cry: It materialised my emotions while playing a game by me actually muttering the word 'wow' while playing in certain spots. There are loads more but these are just what I could think of off the top of my head.
If you could give a budding level designer a short piece of advice to help them succeed, what would it be? Your work is going to suck for a long time, get used to it. If someone is being a dick about your work, they probably have a good point. Listen to them without bias. This will push you beyond what you thought you were capable of. You made the level, no s**t its easy to understand by you — other people HAVE to play it before anything is considered good. Scale will make or break you. Do a lot of scaling tests in every game you want to develop for before attempting anything else.
MapCore would like to thank Jean-Paul for his time, and wish him the best of luck with his future projects. You can enjoy more of his work by visiting his portfolio and Tumblr. He's also looking for people to help out with testing his latest Team Fortress 2 map; simply download 'cp_imbricatus', take a peek at the
