    Mazy reacted to Radu for an article, Level Design in Max Payne: Roscoe Street Station   
    Level Design in Max Payne: Roscoe Street Station
     
    Max Payne is a third person shooter developed by Remedy Entertainment and published on July 2001. At the time of its release, the game gained critical acclaim for its use of the bullet time mechanic - a special ability that slows down time around the character. Inspired by Hong Kong action films and hard boiled detective novels, the game focuses on intense action sequences and the protagonist's internal struggle as he attempts to avenge his murdered family.
    The game's story is structured under three parts, each containing several chapters. For the purposes of this article, we will take a look at Chapter One: Roscoe Street Station, from the first part of the game, and deconstruct the level progression as well as state design decisions when encountered.
     

                                                                                     1                                                                                                                   2                                                                                                                3
    The level begins with a cutscene of Max riding the subway train towards Roscoe Street Station to meet with his friend Alex. As soon as Max gets off the train, he remarks that “The station was drenched in gloom. Alex was a ghost nowhere to be seen. I’d have to look for him”. Although we aren’t given much information to work with, it’s enough to build a sense of mystery and give the player a goal.
    Taking control over the character, we discover that our main path is blocked (1) and are forced to explore a side area (2) where more narrative is to be revealed. As we burst open the doors of the personnel room, we stumble over the body of a transit police officer (3). Once again, a quick cutscene centers on Max while he delivers his lines and sets the tone accordingly: "Death was in the air at Roscoe Street. I'd have to find Alex fast." At this point, Max pulls out his pistol and we can either return to the starting area or explore the room for hidden ammunition and health. Doing the latter teaches the player that exploration is rewarded through much needed supplies.
    On our way back, we encounter our first two enemies and notice that the main path is no longer blocked. Though, If the player takes his time and waits around the corner before engaging the enemies, bits of story will be delivered by them, explaining their reason for being there or informing on the overall situation. And as trivial as that sounds, it can have a major impact on immersion and believability. Clearly this is something the developers have identified early on and implemented throughout the game. Giving the player the option to advance at his own pace goes a long way and makes for a more dynamic experience. Those who want to rush through the levels can do so. Others that want to explore and listen to bits of story can do that as well. It’s an ideal situation that satisfies both worlds.
     

    4
    After our first encounter, we can proceed through the main path where we immediately find two more enemies. As previously mentioned, we have the option to directly engage in combat or wait for the enemies to reveal additional information. An important thing to make note of is that despite the fact that the gameplay space is tailored around the player’s needs, the environment always feels natural. A good example is this specific bit (4), where the player is now emerging from a set of stairs and can dive on his side towards a nearby mail box for cover.
    When designing a space that is supposed to represent a real life location, it's essential for the level designer to always keep in mind that everything placed in the scene must abide by the real location's logic. Of course, adding something unusual or out of place is a good way to draw the player's attention, but in general we all have expectations of what kind of objects to find in most environments. Meeting those expectations is key to creating a believable game world.
     

                                                                                      5                                                                                                                   6                                                                                                                 7
    Going down the corridor, we hear another enemy, but this time located behind an inaccessible gate (5). Although his placement seems odd, this set-up accomplishes two things. Firstly, it creates an audio cue to draw the player forward. Secondly, it gives the illusion that the environment is much larger than it actually is. It's a simple trick and probably one of the oldest in the level design book, one which the developers have used extensively throughout the game to their advantage. If you find yourself creating a fairly linear level, simply adding a few inaccessible areas is a quick and painless way of providing some visual depth to your environment. As in real life, there are plenty of areas that we cannot access.
    Continuing with the idea of guiding the player, we begin to notice even more ways of doing that. This time our direction is implied through arrow signs in combination with an enemy audio cue (6). And after encountering the said enemy we acquire a new weapon type, the pump action shotgun, as well as discover the Subway Control Room (7). Unable to access it, Max elaborates that “The security panel let off a mocking cackle. I’d need the right code”. Without knowing specifically why we need to gain access, we can nonetheless conclude that opening the Subway Control Room is somehow tied to the level progression in some way. Turning to our immediate left, we begin to descend to a closed station.
     

                                                                                       8                                                                                                                 9                                                                                                                10
    At this point, having also acquired the shotgun, the difficulty starts to increase as we encounter three enemies on our path. Once they have been dealt with, we find ourselves in a fairly elaborate space with two options for exploration:
    Taking the path to our right, we end up in a room (8) designed to replenish the player’s ammunition and health. Going to the back of this room, we locate a corridor leading to a locked grate door. Even though we cannot open it, reaching the end will deliver additional information through the means of dialogue between two enemies situated on the other side. In contrast to previous encounters, this time we have the option to kill our enemies by shooting a nearby propane canister. After dealing with them, Max notes that "The gate was locked. I would need to find another way to get to the tunnel". This gives us a hint as to where we need to go in order to progress with the main goal.
    Opting for the path to our left, towards the end of the station, we locate a personnel room, a bright yellow maintenance train (9) and a small supply room. Checking out the maintenance train, Max states that "The power to the rail had been cut. I'd have to get it back on to get the train moving". Looking to the opposite side of the train, we notice a tunnel blocked by a series of wooden boards. Putting two and two together, we must find a way to power up the maintenance train and crash though the boards to reach the level's final area. Of course, now we realize why we must gain access to the Subway Control Room. Turning our attention away from the train, we open the door to the nearby personnel room. Inside, we find a transit police officer held at gun point by an enemy (10). After killing the thug, the officer informs us that he can access the Subway Control Room and so we begin to backtrack. Having reached the security panel, the officer unlocks the door, but is shot dead by an enemy already on the inside.
     

    11
    Reopening the door, we notice the enemy has retreated to a secondary room. Pursuing him, we encounter 3 additional thugs, totaling 4 enemies, the most we have yet to fight at once. It's important to notice that, as we advance through the level, the number of enemies we encounter at a given point increases, but in a manner that is fluid and balanced. So far, the pattern has been to include single enemy encounters between group encounters. This way, the player doesn't constantly feel overwhelmed and has time to recuperate before a larger fight. 
    After dealing with the enemies, we discover a third smaller room to the back. Inside this room there is an electric panel (11) that controls the subway power lines, a cabinet with health supplies and a series of camera displays. Using the button on the electric panel triggers a green line to rise on it's display, giving the player visual confirmation that power is now back on for that specific line. Additionally, using the nearby camera display will show an image of the bright yellow maintenance train and compel Max to state that "The train lit up like a Christmas tree. The power was back on". 
     

                                                                                           12                                                                                                           13                                                                                                              14
    We then proceed to backtrack to the train. Backtracking again. Sometimes, and especially if overdone, this design decision can become tedious and potentially confuse players. However, when used sparingly in design and with a bit of logic, forcing the player to go back and fourth between parts of the level in order to progress can make the environment seem more connected as a whole. Backtracking can also prove to be a good way of making the most out of a given environment by squeezing as much gameplay as possible.
    Once we have reached the train, we can either immediately operate it or explore the area behind it for ammunition. Manning the wheel (12), the train begins to accelerate and shortly crashes through the wooden barricade. Advancing in the tunnel (13), we encounter 3 enemies and reach the area seen previously from the locked grate door. Our only path to follow now is through a rusty door leading to the next level (14). While we didn't accomplish our primary goal in this level, we still managed to gather information about the situation, be it directly from Max's lines or indirectly from the enemy dialogue. 
     
    Conclusion
     
    Despite it's ever growing age, Max Payne still proves to be relevant even today. Examining how the gameplay unfolds in Roscoe Street Station, we can only conclude that the people at Remedy Entertainment are without a doubt true masters of their craft. And for those passionate about designing single player levels, here are 10 principles that we can learn from them:
     
    Story is revealed in small amounts to keep the player interested for more Exploration is rewarded through useful items Inaccessible areas can give more depth to the environment Players that want to be engrossed in the game world are rewarded with additional information Environments are designed with a certain logic to meet player expectations  Players are guided through subtle visual language or audio cues Progression obstacles are designed to be relevant to the story Intelligent backtracking uses the gameplay space to it's full potential and makes the environment seem more connected Interaction with the environment is reinforced through audio-visual feedback Properly balanced difficulty allows the player moments of rest and doesn't constantly overwhelm with enemies

    (New logo by Yanzl)
    I'm sure that by now most of us have our sleeves rolled up and are ready to tackle yet another year, but before we move forward let's take a moment to look back at what 2017 meant for our community. It was a time of immense growth for both professionals and amateurs alike. A time when everyone seemed to have surpassed their former selves. And without slowing down, some have even managed to land their first job in the industry. I don't know what this new year holds, what challenges to overcome will arise, but I know for certain that I'm excited to see everyone become even greater!

    Mazy 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.”

    Mazy 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.
    Hoxton Breakout
    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.
     
    Level Structure
    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. 
    The Quests
    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.
    Discussion
    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?

    Mazy reacted to will2k for an article, Displacement Vs. Func_detail - A comparative fps study   
    What is the question?
    Ever since the dawn of humanity, this question was the center of a colossal debate. Greek and Roman philosophers tried to solve it to no avail. Alchemists in the Middle Ages gave it a go and failed miserably. Even Industrial Age scientists touched on the subject with no big breakthrough.
    Luckily for everyone, I am here today to answer this question and put an end to a centuries-long argument: What is better in terms of fps, func_detail or displacement, in the context of the Source engine? If you were expecting an existential question, I am deeply sorry to disappoint you but hey, life is full of disappointment.
    The study
    This is going to be a short but sweet article; fewer words, more numbers and screenshots. The study is pretty straightforward and systematic. To make things fair and square, I will create 2 exactly identical test maps: In one, everything will be turned to func_detail while the other will have everything switched to displacements. I will then proceed to record the localized fps in these maps from a preset location and compare. Pretty simple, isn’t it? Well, it should be as the whole purpose of this study is to compare func_detail vs. displacement in absolute terms while keeping all other parameters constant.
    The cases
    The first map to test is the one made of displacements. Here is the screenshot showcasing the fps.

    The map itself is very simple consisting of 7 identical houses placed at predetermined locations and surrounded by 4 walls. The houses are detailed enough to put some slight pressure on the rendering engine. For the skeptics among you, here is a wireframe in-game shot to show that everything is made of displacements.

    To refresh your memories, in Source engine wireframe mode, green is displacements, pink is brushes (world, func_detail, brush entity, etc…), blue is props, and yellow is decals/overlays. The recorded fps in this map is 289. We now move to the second map, the func_detail version to check how the frame rate is faring. Here is the awaited screenshot.

    Surprise, surprise. The fps is 330, much higher than the displacement version. Here’s the wireframe shot to put your mind at ease.

    Honestly, I was thinking the figures would be more on par as the engine handles both details and displacements pretty well, but in the end, Source is about BSP so I guess brushes would get a slightly preferential treatment over polygon meshes (conspiracy theory ensues).
    The question that forces itself now is: Should we rely solely on func_detail in our maps? Of course not. Both func_detail and displacement have their advantages and inconveniences and leaning exclusively on one will inevitably lead you to a dead end. The best thing to do is get the best of both worlds by using them together.
    In our little test map, how about we mix things up in a third version: let us make the house walls out of displacements while having the doors, windows, frames, and roofs made of func_detail. Incoming screenshot, brace yourselves.

    Much better, isn’t it? We have now 311 fps, a very nice middle ground between the 330 fps of func_detail and the not-so-bad 289 fps of displacements. The mandatory wireframe shot follows.

    So, what can we learn from all this? Well, apart from the obvious places where displacements are mandatory for the organic mesh sculpting (rock formations, cliffs, bumpy/twisted roads…), it is a good idea to spread some more displacements around your map to alleviate the total brush-count that you will inevitably hit the maximum in a highly detailed map. Your fps will remain high and you will enjoy the margin to keep adding structures to your map without fear of reaching the maximum allowed total brushes (substituting brushes with models/props is another viable solution that is not in the scope of this article).
    I’m a man of science and I know that one example is not enough to draw conclusions. That’s fine, I have a second test map to investigate what we established before. The concept of having 2 identical maps is still the same, however, this time, we will spice things up by adding some static/physics props and some decals here and there. We will start with the displacement version.

    230 fps, not too shabby. Let’s check another angle.

    220 fps, more or less, on the same level as the previous number. Now for the wireframe shot.

    The tree cards in the background are func_brush in both maps (the detail and displacement versions), so it’s a level playing field in this case.
    Now for the moment of truth you all have been waiting for: will the detail version have better fps to support my earlier findings or will I be publicly embarrassing myself? A screenshot to the rescue.

    I knew I was right, never breaking a sweat (apart from the nervous cold sweat I just wiped off my forehead). 255 fps for the first location A. Let’s check the other angle or location B.

    250 fps. Bam, sweet victory…sorry I got carried away a bit. Ahem…Let’s get back to being scientific, shall we. Here’s the wireframe proof.

    Let’s recap all the action and numbers in a nicely formatted table.

    You can notice the fps gap between the func_detail and displacement versions in both test maps whereas the “mixed” version considerably narrowed this gap. The numbers have spoken.
    The bottom line
    The bottom line is, if you rely only on func_detail, you will hit the maximum brush-count allowed in Source and severely limit your map and creativity. You might also run into T-junction issues as well as parts of your geometry flickering and disappearing from certain angles in densely func_detail’ed areas.
    On the other side, if you stick to displacements alone, then you will have lower fps than a func_detail map version. You might also run into visible seams and un-sewn displacement issues.
    Having a clever distribution of both func_detail and displacement in your map is the way to go. You will have high fps, better lighting around the edges, and organic sculpting while not getting anywhere near the total brush limit; the best of both worlds.

    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.

    Mazy 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.
     
    Lightmap baking
    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.

    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:

    Or...

    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:

    Another 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: 
    https://www.desmos.com/calculator/1oboly7cl0
    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!

    Mazy 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.

    Lighting
    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.

    Final thoughts
    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!

    Mazy 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.
     
    Debugging
    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.
     
    Comparisons
    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?
     
    Casts
    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!

    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
    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
    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.
    Our door:
     

    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.

    Wrap-Up
    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.

    Mazy reacted to Thrik for an article, Introducing MapCore's new logo and store   
    Designed by professional designer Arthur de Padua (AKA Thurnip), the new logo was developed over a period of many months and incorporates some of the successful themes that came up during the logo design contest we had some time ago. Unlike the existing logo which only existed as a low-resolution render, this one is perfectly crisp and comes in numerous formats suitable for print — allowing us to finally offer high-quality merchandise.

    So, head over to the MapCore store if you want to show your MapCorian allegiance in public! All items come as a 'Regular Edition' (no profit for MapCore) and 'Donation Edition' (£5 profit that goes towards MapCore hosting/development costs).

    We're currently offering a small but carefully designed selection of products. Once we make sure everything's running OK and we don't need to change vendor for whatever reason, more products will be added. We'll also soon be adding a way for you to donate while receiving a small token of appreciation (e.g. a sticker that can be bought for £5, £10, or £20) for those who want to support us but don't necessarily need or want a T-shirt, etc.

    If you buy anything, be sure to post some photos for us to look at! I have some orders on the way, so will create a thread for such snaps if nobody else beats me to it. If you'd love to buy something but the item you want isn't available, don't hesitate to leave a comment or get in touch with me — I'm happy to build up the products based upon what people want.

    Mazy 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.
    End product:
    First iteration:
    Reference photograph:
    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):
    Based on:
    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).
    Phase 1:
    Phase 2:
    Phase 3:
    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.
