    ellicott

    By LFthaMENACE, in General,

    here is a map originally made for garry's mod by my friend and never recontinued, so i decided to recontinue it and make it into a playable map for CSS.
    enjoy(?)

  • A problem in all "aim" style maps, with a potential solution?
    After playing to much and many aim maps, I realized that my flick shots were only accurate horizontally; so I tried making a map that made your opponent spawn on a different vertical level than you. This not only to increase vertical aim and muscle memory, but also to increase complexity with having to visually keep track of more potential angles from above/below as well has horizontally. However I think I made a shocking discover, most of which is anecdotal since I don't have enough time yet to make a numerical statistical comparative study. However after practicing on my map for comparatively similar amounts of time to another similarly sized standard aim map, I feel my aim is much more accurate. I will be starting to collect data on this, Ill publish it here soo. Anyways for mapping I then made it even a little more complex by having it spawn you on the same level as you opponent 25% of the time, to increase constant "looking up and down". Which should hypothetically increase even more vertical movements. I even added: ladders, stairs, cars, trains, colorful lighting and much more. In it's current development it's only good for 2v2, 3v3, 4v4...
     
    I believe for this increase in uniform range of comfortability in all axes of shooting could influence more of a demand for vertically emphasized maps in the base game! Please let me know what you think and any improvements I should make!

  • Introduction
    Have you ever looked at Valve's map loading screens and can't figure out how they added those damn icons, backgrounds, and more? This article will provide some information about it.

    A repository on Github that will allow you to better understand the location of the files.

    📋 Note: Text surrounded by arrows indicates what needs to be entered here. Arrows should not be written, it is only necessary for a more convenient understanding of important elements. For example, instead of <mapname>.png I will write de_dust2.png
    📋 Note: Spoiler blocks replaces code blocks

    Background
    The loading screen uses PNG images as background. You need to create two images, where the first image will be have resolution 640x360 and the second will be have 1920x1080. After creation, you need to put the images in these paths:

    Radar
    Loading screen uses default radar file. If you want to use some image instead of the radar that the player should not see on the map (for example, a screenshot of the map with heroes, as is done in some of Valve's cooperative maps), then you should use heights that will hide the unnecessary image somewhere in 32 thousand units from the zero point of the map.

    In the already created TXT file of the radar, we prescribe this code that adjusts the high-altitude images:
    The final version of the files needed for the radar:

    The problem with vertical sections of the radar
    If the sections contain the same values in AltitudeMax and AltitudeMin, then the game just crashes without any messages. The same values can only be in one of the parameters!

    Problem code example:
    Correct code example:

    Title
    I tried to find a file that regulates the names of official maps, but nothing came of it. For now, the name depends on the Steam Workshop and some sort of Valve magic file.

    Map icon
    The loading screen uses SVG for the map icon. Valve uses Adobe illustrator to create and export the svg.

    Export your svg
    You need to create a document with the resolution you want (Valve use 35x35 or 80x80), create your nice gamemode/map icon, and then save it (File > Save As) to this path:
    "../Counter-Strike Global Offensive/csgo/materials/panorama/images/map_icons/map_icon_<mapname>.svg"

    Settings for the Save As panel
    SVG Profiles: SVG 1.1
    Fonts:
    • Type: SVG
    • Subsetting: None (Use System Fonts)
    Advanced Option:
    • CSS Properties: SVG
    • Decimal Places: 3
    • Encoding: Unicode (UTF-8)
    • Addaptive SVG / Responsive: Disabled
     
    Description
    Go to the map folder and create a blank TXT there and name it with the BSP name, for example: de_dust2.txt

    Adding an official command with a list of authors
    Open an TXT file and write code like this:


    Using HTML syntax
    You can use the html syntax without COMMUNITYMAPCREDITS, but I am giving an example with this command.

    Open an TXT file and write code like this (Use HEX or RGB for colors):

  • De_coralline

    By griefyn, in Development,

    de_Coralline is a map I've been making since the release of the not very desired map de_veteran_10, from the beginning I started to develop it in silence without talking much about well... a lot of time passed and my map was already in beta, version that I wanted to launch it but the computer had some problems causing me to lose all the files including all the maps I was making at the beginning until 4 months before the year ended and then I started to redo it with an entirely new layout;
    Welcome to de_coralline, de_coralline is a map that takes place in a village / castle of the queen coralline well... the map has a history and since the beginning of the creation of the map concept I always thought of placing statues de_piranesi style that would tell the map history in general this is the basic understanding of the map concept
    Currently it is in BETA version 1.5 and the final version of the beta is 3.0, my concept of the beta is as follows
    Beta Phase:
    Version 1: work on the constructions, make sense of them Version 2: Detail the ground and buildings from the inside Version 3: Put Developer Props on the entire map, and make the map make more sense, ending the beta Well... the concept is very simple but I ended up changing the layout a little making the map stay in the middle of the 3 phases so the number 1.5, and any english mistakes.. just sorry i'm not usa american.

  • Static Prop Combine in Counter-Strike: Global Offensive
    A step by step guide
    thanks to @untor
    What is Static Prop Combine?
    Static prop combine, or informally speaking "autocombine", is a new feature in CS:GO's VBSP.
    It allows VBSP to merge together multiple static props into a single static prop, either automatically or with user-defined rules.

     
    What is static prop combine good for?
    Static prop combine is another feature to optimize your maps. Most people might think that "the less geometry rendered the better". So if you use small props, it's easier to hide what is not visible.
    That's not wrong. But there is a problem:
    In Source, there is one draw call per model per material. And these draw calls are very performance-hungry.
    That's where static prop combine comes into play:
    By combining models sharing the same materials, less draw calls are performed, which greatly helps optimization.
    Valve has stated that Nuke runs 40% faster after they implemented static prop combine.
     
    How do I use static prop combine?
    The static prop combine feature was added in 2016 with the release of the reworked de_nuke. But since then it was not (?) used by community mappers, there are no (?) guides on the Internet except this documentation.
    @untor helped me to make static prop combine feature do its job. So we decided that it's time to publish a step by step guide how to use static prop combine.
    We presuppose that you are already familiar with the creation of props  
    0. Backup your CS:GO folder (optional)
    We do not take responsibility for any damage done to your files. So it's time to backup your game files now if you have not already. In general we recommend to duplicate your "Counter-Strike Global Offensive" folder, so you can use a separate installation of CS:GO for mapping while keeping the other one clean for playing.

    1. Source files
    You must have the source files of the models you want to be combined. Usually 3 files for each prop:
    *.qc reference mesh (supported formats are *.smd, *.dmx and *.fbx) physics mesh So if you want to combine props made by you, you should already have these files.
    If you want to combine props made by Valve, you will need to decompile them first. And then change the names - otherwise, the version of the prop that is packed in the VPK would overwrite your version.
        
    In this guide we will use two different pipe props:

    You can download the example files here (contains the *.qc and *.smd files) :
    example.zip
     
    Browse to "...\Steam\steamapps\common\content\csgo\"
    Create a folder "models". In our example we have another subfolder "example". Save the model source files there:
     

    These are our QCs:
    pipe_straight.qc
    pipe_curved.qc

    Notes:
    Restrictions for the *.qc:
    Only the first $body is recognized. $model is not recognized. $appendsource and $addconvexsrc are not recognized. You can only use $upaxis Z or Y.  
    2. Compile your props
    Your models have to be compiled from this directory now:
    Open your model compile tool (I use Crowbar)
    Then browse to "...\Steam\steamapps\common\content\csgo\models\example\" and compile the QCs.
    The compiled model files should be in "...\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\models\props\example\" now.
     
    3. spcombinerules.txt
    Browse to "...\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\scripts\hammer\spcombinerules\"
     

    There you will find "spcombinerules.txt". In this file the combine rules for Valves props are defined. It is a standard KeyValues-formatted text file. Each entry follows the format below.
    Rename it to "spcombinerules_valve.txt" (or whatever you want) and create a new text file "spcombinerules.txt".
    Then copy and paste the following into "spcombinerules.txt" and save it.
     

    4. Stub QCs
    Stub QCs are QCs which contain a base template for the QCs which static prop combine generates. Generally, they should only include:
    $staticprop $surfaceprop $cdmaterials Any $texturegroups used by the models. Browse to "...\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\scripts\hammer\spcombinerules\qc_templates\".
    In our example we create a new subfolder "example", open it and then create a text file and rename it to "pipe_combine.qc":


    Copy and paste the following into "pipe_combine.qc" and save it:
     
    5. Compile your map
    Add some of our example props to your map in Hammer and compile the map.
    In our example we use the following compile parameters for VBSP
    Compile parameters (full list here) :
    -StaticPropCombine: Merges static props together according to the rules defined in scripts/hammer/spcombinerules/spcombinerules.txt. This lowers the number of draw calls, increasing performance. It can also be used to lower the number of static props present in a map.
    -StaticPropCombine_AutoCombine: Automatically generate static prop combine rules for props that VBSP deems should be combined. Note: This does not write to spcombinerules.txt.
    -StaticPropCombine_ConsiderVis: Instead of using the distance limit, combine all props in the group that share visclusters.
    -StaticPropCombine_SuggestRules: Lists models sharing the same material that should be added to spcombinerules.txt.
    -StaticPropCombine_MinInstances <int>: Set the minimum number of props in a combine group required to create a combined prop. Tip:Valve had this set to 3 for the new Dust 2.
    -StaticPropCombine_PrintCombineRules: Confirm: Prints the combine rules?
    -StaticPropCombine_ColorInstances: Instances of combined props get colored.
    -KeepSources: Don't delete the autogenerated QCs and unpacked model files after finishing.
    -CombineIgnore_FastReflection: Combine props, even if they have differing Render in Fast Reflections settings.
    -CombineIgnore_Normals: Combine props, even if they have differing Ignore Normals settings.
    -CombineIgnore_NoShadow: Combine props, even if they have differing Disable Shadows settings.
    -CombineIgnore_NoVertexLighting: Combine props, even if they have differing Disable Vertex lighting settings.
    -CombineIgnore_NoFlashlight: Combine props, even if they have differing Disable flashlight settings.
    -CombineIgnore_NoSelfShadowing: Combine props, even if they have differing Disable Self-Shadowing settings.
    -CombineIgnore_DisableShadowDepth: Combine props, even if they have differing Disable ShadowDepth settings.
     
    6. Success?
    The combined props look exactly like the single props. So how can you be sure that the static prop combine process was successful?
    - Once the map is compiled, the combined props will be packed into your *.bsp automatically.
    - If you add -keepsources to the compile parameters, you can also find the combined props in "...\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\models\props\autocombine\*name of your map*\"
    and their QCs in "...\Steam\steamapps\common\content\csgo\models\props\autocombine\*name of your map*\".
    - If you add -StaticPropCombine_ColorInstances to the compile parameters, instances of combined props are colored in CS:GO.
     
    7. Additional notes
    Hammer:


    - You can manually disable static prop combine for individual props with the "Disable Prop Combine" keyvalue.
    - Prop scaling (Uniform Scale Override) is not supported yet (?)
    - If the original props don't have a collision model, you will have to set collisions to "Not Solid" in the properties. Otherwise the combined prop will be solid (automatically generated collision mesh; causes problems).
    - If the props differ in specific keyvalues, in most cases the default (e.g. Alpha) or the higher value will be used (e.g. fade distances)
    - Props that differ in the below keyvalues will NOT be combined, unless manually overridden with the appropriate VBSP option:
    Render in Fast Reflections (-combineignore_fastreflection) Ignore Normals (-combineignore_normals) Disable Shadows (-combineignore_noshadows) Disable Vertex lighting (-combineignore_novertexlighting) Disable Flashlight (-combineignore_noflashlight) Disable Self-Shadowing (-combineignore_noselfshadowing) Disable ShadowDepth (-combineignore_disableshadowdepth) - Props that differ in the below keyvalues will NOT be combined:
    Skin Color Disable Flashlight  
    TO DO
    some fps tests with an actual map! which gives better results: " -StaticPropCombine_ConsiderVis" or prop combining based on distances? Is there a console command to display the number of performed draw calls/props? ...

  • Creating a custom grass variant for the Danger Zone
    Open your GCFScape and after open pak01_dir.vpk in "Counter-Strike Global Offensive/csgo" go to "materials/hr_massive" and found there broken_road_1_4wayblend_1.vmt. Extract that file into your materials folder, for example: "../csgo/materials/my_project_folder", and rename it, example: my_custom_4wayblend_material.vmt.
      Go back to pak01_dir.vpk and find the detailsprites_survival.vmt file in "materials/detail", then extract it to "../csgo/materials/detail"
    📋 Note: Rename "detailsprites_survival.vmt", for example: "detailsprites_test.vmt".
      Open the extracted file and delete the lines below to remove the texture that controls the density of the grass.
      Go to "../Counter-Strike Global Offensive/csgo" and find there detail.vbsp. Open it (You can use Notepad++) and find there the cluster "survival_grass_2". Copy that and paste after that cluster, but with new name, for example: survival_grass_theowl.
    Find line (inside the cluster) "associated_material" "detail\detailsprites_survival" and replace "detail\detailsprites_survival" to your custom texture which you created recently. Example: "associated_material" "detail\detailsprites_mycustommap")

      Inside your custom vmt file ("my_custom_4wayblend_material.vmt") you should replace %detailtype survival_grass_2 to %detailtype <your name of cluster inside detail.vbsp>", for example: %detailtype survival_grass_theowl

    Hello! On Mapcore for the first time, so I don’t know if you write something like that here. In general, I recently encountered a problem I had been thinking about for a long time, and the solution was the simplest...

    4wayblend textures stumped me and I didn't understand how to work with them. Since I could not find any articles about this issue, I decided to write about them.

    Connecting and using grass sprites on your map
    In order for 4wayblend textures to use grass, you must write the path to these details in the Map Properties (The path you must follow is shown below).

    Find the Map menu on the top panel in Hammer World Editor > Further Map Properties > Property Name Detail material file > Set the value of Detail material file to detail/detailsprites_survival.

    List of Danger Zone values for Detail material file:
    • detail/detailsprites_survival [dz_blacksite]
    • detail/dust_massive_detail_sprites [dz_sirocco]



    To set the grass to the material, use "Paint Alpha" in the Displacement settings, but be aware that the official materials are governed by a mask that will not allow you to set the grass manually, more on that in another thread.
    If you are using a mask and are experiencing performance troubles due to grass, click "Invert Alpha" to remove the already placed grass.

    Let's start blending
    Go to the settings "Displacement" and select there "Sculpt", then find the button "Blend" and there select the desired texture.

    Blending control:
    • [Left mouse button] – Apply selected texture.
    • [Ctrl] + [Left mouse button] – Remove selected texture.
    • [Right mouse button] + Mouse movement left or right – Resize blending area.

    🐞 Bug: If the camera mode in 3D view is set to "3D Shaded Textured Polygons", then you will not see the drawn part of the texture. Camera mode should be set to "3D Textured" when drawing (fixed in Hammer++).

  • Keeping with tradition, I'd say it's about time we took a look at what our community has achieved throughout the year. If last time I was saying how 2017 was a year of immense growth, then 2018 was surely one of significant change. And it hasn't been without its troubles and anxious moments. No change ever is, but I believe it to be for the best. We've seen some of our friends become parents, change work fields or get their first job in the industry. We've even seen a few pursue their dream projects. And for that, we have to applaud them. It takes courage to keep moving forward and to realise when it's time for something new. In the meantime, I hope this article inspires you and I wish everyone 
    good luck!

    SteamVR - Gulping Goat Space Farm
    by @Steve, @marnamai, @The Horse Strangler, @Sersch and others at Scraggy Rascal Studios
    produced in collaboration with Valve
    "Scraggy Rascal has been working with Valve to create all new SteamVR content, we've been given a lot of liberty to create these locations. Our goal was to create interesting and fun locations for the player to explore. These projects, over the last couple months, have been a crash course in Source 2,VR, project management, delivering within deadlines, working together as a team and personal growth. It has been an invaluable experience and great opportunity ... and we're just getting started!" - marnamai
     

    Darksiders III - Art
    by @The Horse Strangler and others at Gunfire Games
    "Probably one of the biggest challenges the artists and designers faced on Darksiders 3 was working with both a platforming and fully connected streamed world. This meant that everything exists all the time. While we streamed levels in and out, areas couldn't intersect and we couldn't do the classic "Small exterior, big interior" swap. This was especially challenging because of how much verticality our design must support. We had a few "vistas", but for the most part every aspect of the level was accessible. If you can see it, you will likely be able to get there, jump on it, fight around it, etc. Fury, the main playable character can double jump, swing, float, glide and even rocket jump over 10 meters high. Personally for me it completely changed how I looked at art filling up a space. Every single mesh we placed impacted design. Art was design, and design was art." - The Horse Strangler
     

    Europa
    by @[HP]
    "Europa is a relaxing narrative experience. The goal with this game is to offer just enough challenge that its rewarding to get from one area to the other for more than just the visuals by using environmental hazards, platforming sequences and light puzzles that you can beat by exploring.The game is split into linear sections and wider areas, that's at the core of the game and as you play, you keep improving your characters moving ability, which will further exploration and give you the ability to solve newer light puzzles. There's none of the typical character upgrading systems, rather, the levels will offer the incremental challenges and the sense of progression. Europa's main focus lies in environmental storytelling and immersing the player in it's universe with passive storytelling, evoking awe and bliss with colorful watercolor-like art and music." - Helder Pinto
     

    Counter-Strike: Global Offensive - Turnpike
    by @Squad
    "For a while the "Highway Restaurant" theme has been sitting in my little Concepts.txt file. When the Wingman Contest was announced, it felt like the perfect opportunity to turn this idea into a map, as its relatively small size would be fitting for the Wingman gamemode. The casual nature of Wingman made me add some elements that I would not normally add to, let's say, a Defusal map, like the TF2-esque team color coding (albeit subtle), the moving vehicles and the silly bomb target. Additionally, since the playable space is (almost) completely indoors, making it nighttime felt right, as it both emphasizes the interiors and makes for an atmospheric blorange background." - Squad
     

    Dying Light - A New Hope
    by @will2k
    "A full-fledged custom single player campaign that ties in to the original story of the main game. It will see the main protagonist, Kyle Crane,leaving the City for the countryside to search for a specific elusive medicinal herb and bring it back to Dr. Camden who believes it could be the cure to the Harran Virus. This campaign is a one man show as I’m doing everything myself: level design, environment art/detailing, story creation, scripting/quest creation, custom dialog, custom audio, custom materials/textures, custom foliage systems, custom brushes for terrain painting/sculpting, lighting, manual nav mesh tuning, scripted NPCs…" - will2k
     

    Prodeus
    by @General Vivi and Michael Voeller
    "Prodeus is the first person shooter of old, re-imagined using modern rendering techniques. Oh, and tons of blood, gore, and secrets. Creating Prodeus has meant a lot to us over the last year. It feels great to finally be doing something for ourselves. It can be pretty ambitious at times since there are just two of us, but I’m confident we can pull it off. Keep an eye out for the end of February for a big announcement." - General Vivi
     

    Counter-Strike: Global Offensive - Ruby
    by @catfood
    "When I was on vacation in Portugal years ago I was so impressed by the city Lisbon that I really wanted to build a map that has the same vibe. At the time I was already working on different projects so I decided whenever I got enough time to work on a map this size I would go back. So early 2017 the moment was finally there, I went back to Lisbon to shoot (~2000) reference photos then made a list of things that are iconic for Lisbon and started working on Ruby. Adding a lot of height differation, warm colors, tile patterns and ofcourse trams was essentiental to get the Lisbon vibe." - catfood
     

    Subnautica
    by @dux, @PogoP and others at Unknown Worlds Entertainment
    "A mix of Survival, story, mystery, resource gathering, base building with some accidental horror and plenty of deep, deep water. We had not long finished up with Natural Selection 2 and were hungry to develop a different kind of game. During development we were (and still are) a small team but the game kept getting bigger and grew into something far larger in scope than originally planned. So we soon realised that what we had could be turned into something really unique if we put our heads down and just cranked on it." - dux
     

    Unreal Tournament 4 - Chamber
    by @Ubuska
    "I used Halo and Warframe artstyle as a reference. The goal of this project was to make fun and cool looking map with 100% custom art that is 100 mb in file size. To achieve that I used several advanced techniques such as custom vertex normals, deferred mesh decals, no bake, tiling base materials and masks. There are basically 5 or so texture maps used in the entire map,  most of the filesize space was taken by lightmaps. I learned a lot doing this project in terms of composition, art direction and optimization. Hope you enjoy this map as much as I do!" - Ubuska
     

    Counter-Strike: Global Offensive - Pitstop
    by @Quotingmc and Quadratic
    "It is not often that CS: GO receives a new game-mode, especially one as competitively focused as Wingman. I was understandably pleased at the announcement of the 2018 CSMapMakers contest for the mode. Pitstop was my entry where I set out to create a thematically bold centre piece for my portfolio. With the help of my teammate Quadratic and support from multiple Mapcore members, I learnt a lot about taking a level from a simple blockout to completion; I can say for certain I’m thrilled with the end result!" - Quoting
     

    Black Mesa - Xen
    by @JeanPaul, Adam Engels and others at Crowbar Collective
    "While building Xen we had to design, iterate, and iterate (then iterate some more). We took what we thought we knew, and put it to the test. We learned how design and scope work together, and how to build momentum as a team. We are extremely proud of what we have accomplished over the year(s)! Despite the long and occasionally frustrating timeline, it has been a real testament to the commitment that this team and this community have for Half-Life." - Adam Engels
     

    Unreal Engine 4 scene
    by @Vorontsov
    "So I decided I would step out of my comfort zone and create a small environment in an engine I've never used before, UE4. Although I think I did a fairly decent job at the time there were ultimately many nuances I could have done better, but that is the artist dilemma. This project taught me the value of properly blocking out your environment, gathering as many references as you can and to have patience and not rush through assets, when breaking any of these rules I was punished for it. Stay tuned for my next project which will be a giant mech, coming soon Valve time TM." - Vorontsov
     

    Counter-Strike: Global Offensive - Opal
    by @MikeGon
    "My goal with this project was to make a fun and compact defuse map, with a simple level flow, ample verticality, and an overlapped layout! I wanted to have interior and exterior, and break the grid a lot, to avoid having that "90 degrees grid" feel in the layout. I needed to have a vista on one side of the map to help with orientation, so I decided to make it a coastal town, inspired by those found on the island of Skopelos, Greece. Expect more updates in the near future, as I'm not yet satisfied with it. Since this is my only CSGO map, I want to put all my time and effort into it, and focus on quality instead of quantity. Thank you everybody for your support and feedback! <3" - MikeGon
     

    Insurgency: Sandstorm - Precinct
    by @Xanthi, @Squad, @Jonny Phive, @LATTEH, @Steppenwolf and others at New World Interactive
    "Precinct, was a fun and challenging map to work on. We decided early on to melt District and Contact two of our very nostalgic maps together into a single large-scale urban environment. The goal was to preserve the nostalgic feeling and at the same time create something unique and fresh not just a 1:1 copy. In the block-out stage we started playing with different terrain heights, which eventually was the key to accomplish our goal. Terrain height was a bit of a trial and error process; I remember driving up a hill and not having enough torque, oops!!" -Xanthi
     

    Counter-Strike: Global Offensive - Killhouse
    by @FMPONE
    "Killhouse showcases brutal duels, player reaction times, and close-quarters combat. A highly vertical layout ensures the sort of unpredictability and replayability ideal for CS:GO’s 2vs.2 "Wingman" game-mode." - FMPONE
     

    Counter-Strike: Global Offensive - Station
    by @Roald and @untor
    "All experiences contribute to where I am at this point. I am just a hobbiest but I think I learned alot about level design just by doing it and enjoying it. Overal my goal is to improve myself on level design, but also enviorment art. I think I archieved a goal on level design and it's now time to continue on enviorment art. This is where untor morozov comes in. I have met untor a while ago. He made this map 'Waterfall' which was pretty populair. I liked his designs and added him as a friend. When I had this wingman map going on with positive feedback I just contacted him again to work on it with me and since this moment we have had a incredible teamwork. I am gameplay orientated and he is art orientated so we were a great couple. We just enjoyed work on this project and respected eachother and had alot of fun." - Roald
     

    The Gap
    by @Yanzl and Sara Lukanc
    "The Gap is a sci-fi thriller first person narrative exploration video game. You play as Joshua Hayes, a neuroscientist trying to figure out what happened, barely remembering anything about his past. It started as a project for our BA thesis and has now grown into a standalone game. It's also my first "real" indie game project, helping me learn a lot about Unreal Engine 4 and game development in general." - Yanzl
     

    Counter-Strike: Global Offensive - Alexandra remake
    by @Serialmapper
    "My first successful map was born 10 years ago for CS1.6. It was done in just 4 days. Since then it has been ported/improved several times on CS:S then finally on CS:GO. It always had a "dust" theme. Initially i wanted to remake it with an "inferno" style but when the new dust2 came i switched the plan to use the new assets. The map was and is frequently played on public servers especially in Eastern Europe so i had plenty of feedback to improve it. For some it's just another "dust" map, but for me it's my dust2." - Serialmapper
     

    Far Cry 5 - Wetland Turmoil
    by @grapen
    "I wanted to try working with location design in an (imaginary) open world game for the first time, so I made this backwater cabin neighborhood. At the time I also wanted to see what the limits were in Farcry Arcade and how far I could push it. The level has fixed spawns (a limitation of the editor), but I toyed with the idea of making it work regardless from which direction the player would have approached it. The pathing and player guidance is more or less shaped like the number eight, with the church acting as an outlook. Your task is to eliminate all the bad guys. In the end I wanted to do so much more, but couldn't due to technical limitations. All in all it was a fun experience to make it." - grapen
     

    Counter-Strike: Global Offensive - Trailerpark
    by @OrnateBaboon and @Skybex
    "We wanted to make a map for CSGO, using a theme that had not been seen in any previous version of Counter-Strike.The map had to incorporate everyday plausibility, provide for enough variety so that things remained visually interesting,  but also be flexible enough to allow for the use of low geometry for easy grenade strategies. Being able to immediately recognize a theme in a map is always important, so with all this criteria in mind, A trailer park fitted the bill perfectly. There is still some way to go before a full release, but 2018 was a great year for progress on this project." - OrnateBaboon

    "I was inspired by games like stalker and the last of us. The goal was to make something photoreal with a lot of foliage. It took a couple of iterations but I think I achieved the goal in the end. While making this project I've had to learn a lot about Speedtree to make all the foliage, it was a really cool experience. Right now I'm in the army so unfortunately I can't make any more scenes right now, but after I'll come back I'll try to make more scenes like that." - Corvus
     

    Overwatch - Busan
    by @Minos, @[HP], @PhilipK, @IxenonI, Phil Wang, Lucas Annunziata and others at Blizzard Entertainment
    "Busan was a challenging map to make. Due to the game having 12 different heroes on screen we have a somewhat limited memory budget for maps, that includes all models, textures, effects, collision data, lighting information, etc... Fitting three radically different areas (Downtown, Sanctuary and MEKA Base) into one single map budget required us to find new ways to optimize our work. In the end, we were even squeezing kilobytes out of collision data to make it all fit, no kidding! But the result speaks for itself, the map was fun to work on and we are very proud of what we accomplished!" - Minos
     

    Counter-Strike: Global Offensive - Highlands
    by @ElectroSheep, @El Moroes and @'RZL
    "We wanted to make a map in Scotland because, thanks to dishonored 2, we were browsing a lot of references froms this area and we really loved it. I also went myself here in holliday after that. We asked one of our close friends to make some special props, like the police van, the taxi, the phonebox and some others. Unfortunatly the hard development of Dishonored 2 put us in a difficult state where we weren't able to work on the map. So we lost motivation. Then RZL contacted us because he didn't want the project to die so we gave him the keys. And RZL became busy too ^^. Life sometime say NO I guess, hehe. Now Highlands Is my only advanced project I still didn't finished and I'm ready to give it a try, I hope." - ElectroSheep
    "Highlands...is this map is a joke? Certainly no but we can say that the development is quite longer than what we expected. Perhaps we learn well how the famous "Valve time" works? :p No seriously I think we can explain that with the motivation. Of course we were motivated to create something cool with this map but with the time and, I think, with what we live in our life we never took the time to do it correctly...I mean we never had a constant rythm on the map. This (and other personal things) led to the current statut of the map; a still "work in progress" map started in 2014. But ElectroSheep came back and his goal is to finish it, and because he's right, I'll come back too to help him. Just, be patient (again) ;)" - El Moroes
     

    Battlefield V - Fjell
    by @Puddy, @Pampers and others at DICE
    "Fjell was an explosive experiment which paired a new Battlefield dynamic, planes and infantry only, with an epic gosh darn mountain top. Tackling this design combination was like dealing with a bear after you've kicked it in the balls. It was a fun challenge and even though its extreme gameplay is quite polarizing when compared to more middle-of-the-road maps, I am happy that we went there!" - Puddy
     

    Counter-Strike: Global Offensive - Iris
    by @BubkeZ and @Oliver
    "Iris was born out of a shared interest in the TV-show "Seinfeld", funnily enough. One day BubkeZ noticed I had changed my Steam profile picture to a photo of "George Costanza" and just like that the wheels were in motion! In the beginning, BubkeZ had the vision of an old city environment with lots of dirty alleyways and brick architecture. We didn't want to fall in the trap of making the map look too bleak, so we came up with the idea of making a mid-century town set in autumn. While the map certainly have visual elements from the 50's, I would say the overall theme of Iris is american auto-industry. Making the old cars was definitely my favorite part of making this map!" - Oliver

    "I have always been a fan of retro and vintage, so this was like a dream to me. After watching the first season of True Detective, I immediately fell in love with the office set and the way the series was shot. I have definitely learned a lot from this project, mostly lighting techniques that can fill your scene with a story. The goal was to recreate their environment in my own style, and I'm pretty satisfied with how it turned out. I definitely wasn't expecting this much of positive feedback and I'm really thankful for this community. I want to do something with the environments, not just as a portfolio piece, but make a short film or make a small adventure game out of them." - Brightness
     

    Counter-Strike: Global Offensive - Insertion 2
    by @Oskmos
    "Being the follow up to the first Insertion it will have the same overall concept with the spawning and open-world like layout. However this time it will be a more urban setting and overall higher quality art assets. I always love to make environments that feels real. And that are familiar. Its all made up. But the details and various elements in Insertion 2 is from my childhood basically. Friends that grew up in the same place I have recognizes it aswell." - Oskmos

  • The Making of Murky Station: Payday 2
    Payday 2 is a four player cooperative first-person shooter with RPG elements that centers around robbing banks and stealing rare loot. It was released on August 13, 2013 and has since shipped over 50 DLC packs and counting. With a thriving subreddit, it has consistently been in the top ten games played on steam. Today, I wanted to talk about my adventures designing stealth levels for Payday 2 before leaving Starbreeze in January 2018. While parts of this article are specific problems and solutions for Payday level design, I made sure to discuss them in a broader sense. The skill level of this article is for junior to mid-tier level designers, if you are a senior designer some of this article may sound familiar to you.
    I'll start off by saying that Payday's stealth mechanics are not perfect and can be flawed in some areas, but I wanted to focus on the decisions behind the map design, specifically for the heist Murky Station. I'll also break down how we consider using RNG (randomization), and the ways we apply it to objectives and mechanics to keep the level fresh and replayable. This map took 6 weeks to make between 2 people. My partner took the role of Level Builder / Environment Artist and I took the role of Designer / Scripter. Between the two of us, we figured out the scale of the project based on the needs of our studio. The idea was to create a small heist that took around 10-15 minutes to finish with high replayability. There's a lot to go over, so let’s get started!
     

     
    Let's start from the beginning
    Before we start drawing or building layouts, we make the call if we are going to create a Loud level (combat only), Stealth level (avoid combat), or Mixed style map. For the short period of time given to us, we decided to stick to stealth only. Making this decision early on helped us create better movement options for the player and focus our efforts towards balancing patrols and objective placement. We decided that the theme of the level was a small train depot run by a group of mercenaries shipping large weapons. The main objective was to infiltrate the depot and steal an EMP bomb. Keeping the objective simple and intuitive is important in multiplayer games where players can drop in and out of the experience at any point in time.
    We decided to shoot for 10 - 15 minutes of gameplay. Breaking down our main objective into smaller sub-goals that could take about 2 minutes each (this is based on our extensive knowledge of payday 2). It should be noted that this time assessment will change once the player has completed the level a few times. These numbers tend to get cut by a third, or in some cases, by half. With our main objective in mind, we can construct a simple flow diagram for the heist and start to think about possible dynamic and RNG elements that can be used to create a re-playable experience.

    (This is a scripting example from our editor, each entity has it's own function)
    Testing your ideas before scripting them? Wait... What?
    Since 90% of Payday levels are hand scripted, it's important we don't waste time building the wrong things. Testing your objectives and complicated RNG elements has to be fast and efficient. The last thing you want to do is build an entire system and find out it sucks. Most of the time you don't even need animations or even a model to properly test your ideas. At such an early stage some floating debug text will do just fine. You might be asking, what if I don't have debug text or the ability to script? When playtesting levels for Payday 2, a lot of the time we'll get a simple block-out done and then ... here it comes ... pretend we're doing the objectives.
    It might sound crazy (and not everyone can get through it without laughing) but we'll have one of the designers act out the role of Bain, our mission giver, and just spout objectives at us. We'll move through the space and pretend to see guards or hack laptops and delay time based on things we expect to happen. You can basically break down how your systems might work and try out a few possibilities. For example, knowing that you might have two escapes at either side of the map gives you enough knowledge to make pretend decisions. Telling your fellow devs the van is arriving up top and pointing out where to secure loot can help you find out if a location is interesting for the escape or not.
    Even though the artists might giggle, or people from the other teams walking by stop and wonder why they can't see that hoard of enemies. It really works, and can often steer the level in the right direction and prevent us from investing too much time on the wrong objectives. Now, I know this approach won't work for all studios or situations, but all I gotta say is... don't knock it till you try it...  
       
     
    Constructing our Sandbox Layout
    Now that we've pretended to run through our objectives and have gotten used to our basic block-out, let's talk about the layout we built for Murky Station. We went for what i'd like to call "the onion approach", which is pretty much what it sounds like. You'll have multi-layered rings that give you the sense of progression towards the center (or a goal). Essentially, we use the outer layer as the player start and each sub-objective is based inside a different layer until the player reaches the main objective (at the figurative center). This approach is very useful when working with sandbox type levels, especially when the player can virtually go anywhere they want.

    Side Note: We also layer our music track each time a sub objective is finished, creating more suspense and a sense of agency.

    You can see that the outer onion layer is the player spawn (colored green) on the overpass which gives them a full view of the trainyard. From here they can study patrol routes, train-car positions, and possibly objective locations. The overpass can also be used by a player with a sniper rifle to mark guards in the different lanes, helping provide accurate information on guard positions for the players on the ground floor.

    The next layer is breaking into the train yard through a fence around the perimeter. The fence is here to guide the player and give them a visual boundary for the "safe zone" (where no guards patrol). The next layer is searching the train cars to discover where the main goal is hiding, followed by breaking through the vault doors inside of the trains themselves. These onion layers have to be carefully managed to give the proper impression to the player. Too many layers and you might confuse the player or make them forget what they're doing, too few and you might leave them feeling unchallenged or unaccomplished.
     
    Player Mobility is key!
    Mobility is key to providing players opportunities to express themselves and make better decisions while traversing a level. I felt that it was pretty important for Murky Station to allow for different play styles ranging from slow and methodical to fast and dirty. The last thing I wanted was to force players to play a certain way or for the routes to become predictable and linear. In order to do this, I spent the first week of development prototyping and testing out different layout ideas that would maximize paths and choices for the player.
    (Here is a simplified top-down of the routes in the train yard area)


    It became obvious that we would need to allow players to traverse through and under the trains as they cover most of the real estate in the train-yard. Unfortunately the older train assets were not built to go underneath, but lucky for us, the nighttime setting of the level would cover up this fact. There being only 2 of us on this project, I took a crash course in Maya and cleaned up the bottom half of the trains by removing collisions and remodeling them for readability purposes.


     
    The next challenge was to teach the player they could hide under trains and be safe. Payday players haven't been under the trains in any other heist up until this point, so we needed to call attention to that but also show them it was a safe place. Making these spaces dark and in the shadows helped create an illusion of safety but also made it harder for players to find them.
    To help solve this issue we added yellow caution tape as a trim and a dim red light under the wheels to catch the players eye. These combined elements would then be used as visual vocabulary in other parts of the level to teach players something should be explored.


    One of the other ways we added more routes to the level was to build a ventilation system in the lower tunnels. Leveraging the fact that this was a stealth level to create these smaller spaces, especially since they didn't have to accommodate 40+ police officers. The vents allowed players to safely view guard patrols, search for objectives, and move loot. To prototype this, I built a modular vent system using basic mock-up units that allowed for rapid construction and testing. Funnily enough, the first iteration of the vents was too small and caused players’ bodies to clip through the floor. I was able to rework my mock-up units and we settled on standing height instead of a crouching one. Once again we used yellow caution tape as our visual vocabulary to highlight the vent entrance on the wall.
    Modifying the trains and vents is one of the factors that contributed to the map’s success and gave new players more confidence to explore the trainyard and lower claustrophobic tunnels. So now that we've explored the different possibilities for movement and giving the player more choices, it's time to buckle down and get our randomization system built.
     


    Randomizing Objectives to Maximize Replayability
    RNG is one of the core pillars of Payday, so every decision we make is looked at through a lense of RNG. We strongly believe randomization should be meaningful to gameplay and not just added for the sake of it. It’s important to ask questions like: was it worth changing all the cups in your level? Did you gain anything from swapping out all of your cars and buildings? Was creating a third entrance valuable to the level? Maybe one day we'll completely randomize every object in a building down to the smallest cups, but in a game like Payday I personally feel these types of things have diminishing returns and can often ruin a planned design.
    When working with RNG it's important that you ask yourself as many questions as possible to start with a strong foundation, especially if you plan on finishing on time. Something I often see junior to mid-tier level designers forget is to build for scope and set priorities on their objectives. It might sound trivial, but forgetting your priorities can send you down a black-hole that eats away all of your time.
    So how did we go about adding RNG into Murky Station? Breaking down our objectives, we can start to consider what RNG options are available and doable within our one month time frame. I've also labeled them with my personal priorities (low - high).
    Break into the train yard randomize breach locations (low) Locate the Bomb Train randomize train configurations (high) Hack into the train randomize panel to flip sides (low - medium) Open the Vault 4 different vault door / key types (high) Find the Vault keys The map supported up to 40 hiding locations (med - high) Secure the EMP bomb parts 2 escape locations, 1 chosen per playthrough (medium) I focused most of my efforts on randomizing the train configurations, vault doors and key placement. These objectives were critical in influencing how the player would move through the main space and how they could tackle the same area in different ways through multiple playthroughs. In order to accomplish this, I broke down my sub-goals into digestible points of interest and isolated them into their own prefabs (shown below). Doing so allowed me to script one prefab and teleport it to as many locations as I wanted. This approach made the randomization more manageable to script and cut down the amount of bugs that might have formed if I built everything by hand each time.

    Side note: We gave each one of our key / vault prefabs its own unique visual and audio so that players could identify them from a distance or listen if they were close by. Providing them with this level of feedback is critical in helping them make proper decisions while traversing the level.



     
    Now that we have our vault doors and keys figured out, I can begin the planning process of placing them throughout the level. When placing them, each location must meet certain conditions before being finalized. The main goal is to provide the player with a challenge and also encourage them to be creative in tackling the surrounding area. Having designed the layout to have many interesting choke points and traversals, it was fairly straightforward where I could place them. Collecting the keys is one of the more RNG based objectives in Murky Station, sometimes all of the keys are in different corners of the map and other times they are all next to each other. Eventually there was a script clean up to prevent overpowered locations or terrible RNG possibilities, but overall it was a huge success for the level.
    We generally kept the key locations central to the layout and tried not to place them too close to the player’s safe zones. Placing several keys along the outskirts was a nice change of pace from the main lanes, providing a different type of challenge due to the openness of the layout.
    This is what the upper train yard looks like and how the keys are distributed. The lower tunnels have the same amount of keys placed.


     
    We also used the same method for spawning the train interiors and vault doors. By creating one prefab and scripting it four times inside the level (one per vault door type) we were able to randomize the location of the players’ main goal with little effort. The engine also allows us to rotate our prefabs, giving us the option to flip the train interiors.  This added a whole new layer to their configurations, since some of the interior layouts were asymmetrical.
    We ended up with roughly 600 train configurations, 2000 vault door combinations, and 256 sub objective configurations. With 1 of 2 exits being chosen randomly each playthrough, this really changed what types of decisions got made by the players. It also influenced how they would flow through the level and took advantage of their diverse set of movement options.
    On top of that we use non-linear objectives, which basically means you can do multiple objectives at the same time or in some cases, different orders. In Murky Station, players can simultaneously be looking for keys, searching through trains, marking guards from the overpass, and securing extra loot they find. This allows 4 players to comfortably split up to cover more ground and work off each other. A well coordinated team might have two players hacking into the trains to find the EMP bomb, while the others are looking for the vault keys. I find it very important to provide all players an opportunity to contribute towards the main goal.
    Side note: With all of this randomization, you might be wondering how QA can test it all. The short answer: they don’t. We need to build efficiently to insure 90% of the level is solid, and then catch as many edge cases as possible. On the Payday team, the frontline of defense for QA is the designer making the level, It’s our job to test our own work thoroughly! The way the systems above were built would only required 1 prefab to be maintained for each example. This provides us the freedom to go nutty with the customization in the level, knowing it has a low chance at affecting our prefabs. So, as long as we build smart we can cut down the amount things QA needs to test and help speed up production.

    With the objectives off to a good start, let's take a look at how RNG might affect our guard patrols and cameras in the level.
     

     
    Guard Patrols and RNG
    Randomization can have a large effect on how smooth or frustrating a level turns out to be. One of the things we have to keep an eye on when designing stealth levels is frustrating the player through poor patrol placement, amount of guards, and how long they pause at each location. The goal is to create a fun puzzle-like challenge, not a terrible waiting game. Bad RNG might have you sitting in a corner for one minute waiting for the guard to leave, only to have another guard take his place when that minute is up. It's our job as the level designer to help prevent such situations from happening by adjusting our timings, reworking the layout, or possibly the level’s mechanics. This is why it's so important to create a solid base for player movement options from the beginning.
    Since we don't want our guard patrol RNG to get out of hand, we need to be careful about how they flow through a space. Doing this requires it's own personal attention and multiple iterations. Tilt too far in one direction and you'll end up with bare areas that have no guards, tilt too far in the other direction and you'll have too many guards stacked on each other with no wiggle room. The last thing you want is the possibility of a death chain reaction. This is caused when you kill 1 guard, only to have another guard 10 meters away spot that body... forcing you to kill that guard, who eventually gets spotted by the next, ect. In Payday 2, players have a limit of 4 guards they can kill before the alarm goes off (on all difficulties). In our levels, we have to actively manage the amount of crossover between paths and how often guards might meet.
    In the first test pass for Murky Station I ended up with a good amount of coverage for my level, but the downside was that some sections could randomly get 8 guards piled up.  After a bit of playtesting and redesign, I decided to break up my patrols into smaller loops and add more points. This increased the amount of coverage and kept the patrols more consistent. It also lowered the maximum guard stacking to around 4 and drastically reduced the amount of death chain reactions that could happen.

    First pass patrol locations

    Second pass patrol locations

    (the new paths provide the same amount of level coverage with a less chance of guard over-stacking) 
    A fresh take on an old mechanic
    In most of our stealth levels we use random static security cameras to challenge the players’ skill at avoidance or sabotage. The players have multiple mechanics in order to deal with them in a variety of ways, but we hit a brick wall when discussing options for Murky Station. Due to the hallway nature of the layout and the surrounding structures, we were left with very few options when it came to camera placement. With so few options, the cameras would be no longer modifying the level in a positive way. We also found them at odds with the design of the level, since you were supposed to be searching for a specific train car. If we had cameras pointing at it, you would be able to identify it too quickly and negate the challenge of finding it.

     
    So how did we fix these issues? Getting rid of the cameras was not really an option, so we began brainstorming and looking for assets that might be of use. It's important the core camera functionality remain intact and also continue to meet our core pillar of randomization. We discovered an old drone asset for one of the previous levels and began prototyping a few ideas. The design we ended up going with provided us the coverage we needed, while also creating a new challenge for the players to overcome.


     
    Each train can spawn up to two drones, which will then fly around the perimeter of the train and scan for players and bodies. Randomly throughout the level, three to four drones will be activated to begin their scan. The loop takes about 30 seconds before they return to their trains and deactivate. The cycle continues like this every few minutes until the level is finished.
    On harder difficulties, more drones will spawn and they will become indestructible.
    What's great about the drones from a design perspective, is that we can dynamically modify how the level gets played and prevent players from getting comfortable in using the same routes each play-through. Some players will avoid lanes with drones, more skilled players will dodge them using their movement options, and some players might even get trapped and need to think of a new routes. Let's take a look at the patrols and drones in action.

    Closing thoughts
    Murky Station was such an enjoyable experience to work on that I still play it to this day. When you break down the objectives and how they influence one another in a co-op space, you can begin to see the bigger picture and how a well-planned level with controlled RNG elements can stay fresh and replayable. Experimenting with different types of RNG is something I find very interesting, especially when you combine it with level design. I hope my article gave you some more insight into how we build with RNG and why we consider it one of our core design pillars. If you found this article helpful, let us know in the comment section!

  • 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  
  • Intro
    Titanfall 2 was one of the best FPS titles of 2016, featuring a very strong single-player campaign with interesting combat and puzzle gameplay for both players and their Titan. Additionally, each level featured its own special twist: "Effect and Cause", for example, presents players with a memorable time-traveling mechanic.
    The time-travel mechanics of "Effects and Cause" serve couple of purposes, influencing not only the way players traverse the environment and its associated obstacles, but also how they fight through the level's combat scenarios. Two different time periods are a threat to the player, so the designers decided to allow players to see where the enemies from the past are located.
    Once you move from past to the present, enemies leave a small blue particle in the place where they had been standing. Although the effect lasts no longer than two seconds, it’s enough to help players plan their next move. This twist on encounters makes them much more interesting and dynamic.
     

     
    For "Effect and Cause", the developers created distinct enemies archetypes with different engagement distances and attacks for each time period. In the present (a destroyed version of the map) the player deals with robots and wildlife. In the past, players face armed guards in the facility. Eliminating the danger in one reality does not make it disappear in the other, forcing players to think constantly about their position versus the enemies in the different time frames.
    Let’s discuss three selected encounters from "Effects and Cause" in-depth to see how they work in action!
     
    Encounter 01
    The first encounter where players freely use the time-shift mechanic starts shortly after players exit a lab area. Here, enemies are located only in the past, when the facility is operating and functional. This prevents players from becoming overwhelmed with two types of enemies in two different realities within the first big encounter of the level.
     
    Layout

     
    Combat space
    This encounter is set up in two distinct spaces. The first space is a big room with a single entry point in the form of a double door opened by a panel, with combat focused at the far end of the room. The second space is a large corridor with a pocket in the middle and a security room at the end. A panel in the security room must be used in order for the player to progress.
    Both encounter spaces are divided by a time-shift puzzle, the only way to continue onto the next arena. This time-shift puzzle serves as combat gating and also adds variety to encounters that are otherwise only about shooting. The gating also teaches the player that some spaces cannot be traversed in any time period, and that the only solution to the obstacle is to find alternative routes.
     

     
    Enemies
    There are eleven enemies in this encounter: four located in the first room, and seven in the second room. Once you eliminate the two enemies in the first room, the remaining two enemies get into position. The second space has a fixed number of soldiers, with no additional waves. All the soldiers are using guns or rifles. The advantage/challenge to the player in this encounter comes from the number of the enemies, not their abilities.
     

     
    Encounter design
    Once the player enters the first space, they see two soldiers talking to each other. It’s up to player to start the fight and pick their preferred attack method. Once the first two enemies are eliminated, players enter an area with clearly defined architecture and a no-man’s-land inbetween. Players should also see a weapon lying on the desk, a gameplay "carrot" which helps to draw players into the fight. The enemies will hold their positions and try to shoot the player from behind the safety of cover.
    The second area gives players more options, and also allows them to scan the area earlier (both from the first room through the lasers, and also from a vent). The designers ramp up the difficulty here, introducing more enemies into a tighter space.
    With the time-switching mechanics at hand, players can prioritize threats in order to set up their own tactics. It’s clearly up to player how to plan and play this encounter. As there is no threat in the past timeline, players can experiment with going back in time without punishment, ‘escaping’ the combat at any given moment in order to reload, reposition and jump back to the action. This encounter is memorable as it is the first time that players fully use their time switching mechanic, functioning as a safe environment to learn. In other words, it's a skill check and a preparation for what lies ahead...
     
    Encounter 02
    The second encounter worth analysis is much more varied with how it positions enemies throughout the level. It also places enemies in both time periods, serving as a playground for prioritization strategies and other interesting player tactics. This encounter also features more verticality, which helps prevent players from feeling too overwhelmed with enemy forces, while also allowing players to use more of their Titan-piloting skills.
     
    Layout

     
    Combat space
    This encounter is located in a fairly large room with ample verticality. Players enter the space on the upper floor through a single entry point and continue their way onto a balcony, letting players familiarize themselves with the space from above. At the far end of the room, players will spot a staircase going down to the lower level where elevators are located. This area has two big areas of standing cover, accessible on both heights, and a variety of crouch-height cover such as railings, desks and potted plants. This space also has a small side-room allowing further tactical options. This whole area is gated with an elevator door which does not open until the combat encounter is over.
     

     
    Enemies
    This encounter is quite varied in terms of the enemies players face. In the past timeline, players face eleven soldiers: nine regular soldiers and two heavy soldiers with shields. These soldiers come in four groups of two or three each. The solders come with short intervals inbetween each wave, so that the player has time to react and make more intellectual choices.
    In the present, players face three robots appearing almost at once when they walk along the balcony at the top of the space. Once the player goes down, they have to fight four prowlers which appear one after another with a couple of seconds delay between each new spawn.
     

     
    Encounter design
    We start the encounter in the present timeline, with the gate blocked in the past timeline. On the way to the staircase, three enemy robots spawn but do not pose a big threat to players. Once players move down, their attention is drawn to a desk with guns. This helps players to immediately position into a location in front of the elevators.
    Once players shift to the past, enemies start to appear from the elevators. There is not enough cover to fight off all of the attackers, forcing players to prioritize and switch in time to better position themselves for attack. Once players go back into the present, prowler enemies will start to appear, forcing players to continue constant movement.
    This encounter may feel a bit hectic, but it is a good test of both pilot skills and thoughtful time switching. It's the first encounter which forces players to prioritize which enemies they want to deal with first in different time periods. Due to the designer's smart use of the elevators, vents, and robot storage, enemies are brought into the field in an interesting way. But at the same time, enemies are introduced to the player with clear sound and visual cues, so they remain alert to upcoming surprises.
     
    Encounter 03
    The third encounter I want to breakdown is by far the most robust yet. It features different height levels, space divided into two areas, and flanking paths which can be accessed only through certain time periods. It serves as the "final skill check" for all of the pilot abilities and time-shifting gathered thus far in "Effect and Cause".
     
    Layout

     
    Combat space
    This encounter is spread across two areas of vertical space, connected by multiple paths that create nice loops for players to use to their advantage. There is one clear entry point with a wide view of the whole combat space and one exit located in the second area, but the space inbetween offers a great deal of choice in terms of how players can tackle the encounter.
    Playing through the encounter, players will learn that there is a geometry difference between the two different time frames that can be overcome with some of the pilot skills at their disposal. A big catwalk goes around the whole room with additional rooms with guns and ammo on the bottom level, for example. The amount of space available is needed, because the combat space is packed with enemies.
     

     
    Enemies
    In the past, players have to fight twelve soldiers: nine regular soldiers and three heavies with shields, as well as three robots. The enemies are spread out across the whole space of the encounter, but because the areas are connected with each other through multiple paths, the enemies will try to chase and eliminate the player. This means that the encounter feels very dynamic and tense.
    In the present, players face robots: eight prowlers inside, and even more of them outside fighting with BT (the player's Titan). The enemies in the present are hostile to each other, showing players an example of how the enemy AI can actually fighting eachother: information which players can then use to their advantage.
     

     
    Encounter design
    Players enter this area in the past, where they witness a single back-facing enemy, instantly inviting them to perform a takedown. From this point, the encounter is very open to experimentation: the player can either continue in the past and fight a big wave of soldiers coming through the main path (a staircase in the middle), or they can switch to the present, where they will find open flanking paths on both sides of the level. Going with the latter option offers a moment to breathe before prowlers are spawned, but it will also disable an ammo dispenser in the first area, adding consequence to player choices.
    Staying in one place will result in a massive pile-up of enemies in the area, so players are motivated to move around a lot, time shifting when needed. The second area of this encounter is one of the level's biggest in-door combat spaces. If players choose to go into this second area in the past, the encounter will be quite vertical with soldiers located both on the ground and on the upper catwalk. Switching to the present will cause a bigger concentration of enemies on the ground floor.
    Players are given enough space to fully use pilot’s zip-line ability to create shortcuts across the room, accessing the various loops and ammo dispensers needed to create a fair fight despite overwhelming enemy forces. There are very few conditions placed upon this encounter, so players can leave the area and jump into his Titan to deal with different threats at any time. Overall, this encounter serves as a test of everything learned previously, with players having the option to ‘lower’ the difficulty of the encounter using their titan.
     

     
    Conclusion
    The above examples are just a slice of Titanfall 2 gameplay contained within the excellent level "Effects and Cause", but in my opinion clearly shows how this great game was enhanced by its time shifting mechanic. The idea is fairly simple: time-shifting is nothing more than teleportation between two different levels, one layered on top of another, but the strong execution makes for a memorable experience that really stands out in comparison with other shooters. I highly recommend playing "Effects and Cause" as it is both challenging and fun, a level where Titanfall 2's time-shift mechanics comes into focus, providing additional depth to the whole game.

    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!

  • This article may contain slight spoilers   DOOM's Argent Tower is a superb Single-Player level. The Argent Tower motivates players with an obvious goal, expands in scope (almost unbelievably), and masterfully controls pacing. A playground for new a ability and a giant environmental puzzle, the Argent Tower is the best level in this excellent reboot of the franchise.   Now, let's explore the reasons why this level feels so memorable!   OBJECTIVE   Players will know their goal from the outset: climbing the Argent Tower. In addition to verbal instructions, the level's construction and composition never fails to aim you upward. Warm lighting moves up vertically, so that players' eyes are always drawn upwards.     Even the item you acquire in the level's prelude is a double-jump upgrade, which the level then associates with an oft-repeated green light motif. Players will be doing a LOT of double-jumping in the Tower, so the game articulates a method to guide them.     While players may or may not consciously respond to this green-light motif, the designers clearly believe it works as a navigational aid: it is repeated with brutal consistency throughout the level.   SCOPE   When players reach the Tower's inner core, the vast power of DOOM's engine is indisputable. Great music kicks in, monsters spawn all around the player, and the game "gates" engagements without muddying players' central, long-term gameplay goal.     The symmetrical, circular design of the Tower's core proves extremely useful in several respects. Because players can only progress upwards, they get to experience fun combat engagements and jumping puzzles before they are neatly stuffed into small corridors adjoining the main core.   This contrast between the core's verticality and its cramped side passages makes for easily controlled progression through the level and amplifies the awe of returning to the core. In one side area of the Argent Tower, players experience a "monster closet" ambush, a classic DOOM design trope in which a demon emerges from a closet adjacent to a corridor. Here, the designers chose an exploding demon for extra "oomph"!     There's just something timeless about monster closets. That the game dives down to its most granular level (the monster closet) additionally provides contrast to the heights of the massive core.      PACING   DOOM carefully reminds players of their progress ascending the Tower. In one cramped side-area, players are faced with the seemingly trivial task of shooting canisters that underpin an elevator blocking their path. After destroying the canisters, the elevator falls down its shaft.      Half-Life 2 used similar imagery to convey the scale (and ongoing destruction) of The Citadel:     An additional point of this elevator diversion was to slow players down, to keep them away from the showpiece core a little while longer.    New players will take a minute to identify the canisters overhead and discern that they need to be destroyed, because this is a novel task and because FPS players notoriously fail to look upward. Later in the game, the designers repeat the canister mechanic before providing players the BFG, the defining weapon of the series. Without the subtle change in momentum the canisters provide, gaining access to the Tower's rooftop or the BFG would feel too straightforward and simplistic.    Having artificially lengthened the break players take from the core, the designers have guaranteed that environmental contrast will enhance perception of the Tower's scale AND that player intelligence and momentum has been challenged by a new problem. (...but because this is DOOM, problem solving is still ultimately about destroying shit.)     Players complete more than six different jumping tasks including riding a flying drone to climb the Argent Tower and enter a portal into Hell.      Such a variety of jumping puzzles and hazards makes the level memorable and is another technique enlarging perception of the Tower. To be clear, jumping puzzles are universally terrible in every FPS game, but their annoyance here is dulled by the focused grandiosity of the level and the ability to grapple onto ledges. The designers ultimately cared a lot more about giving players a memorable locale than sparing them falling deaths.   CONCLUSION   After reaching the top of the Argent Tower, players are greeted by a giant, climactic battle which ends with a wonderful fade to white.   Only now are players ready to enter Hell confident that they've truly gotten to experience Mars.      It's important to remember that, fundamentally, the Argent Tower is about going from point A (the foot of the tower) to point B (the top). Faced with a similar Tower-landmark, some designers might path this route with nothing more than a simple elevator cinematic or miss countless opportunities to do something special. DOOM's designers, however, missed nothing: they recognized the need to offer players dense and varied challenges, careful pacing, and spatial design rich with contrast.   Later, when players return to Mars, the destroyed husk of the Tower provides an instantly recognizable landmark re-orienting players on their adventure and a tantalizing hint that things are different now.   The Argent Tower goes to show that great levels are not about the destination, but the journey -- and all the controlled chaos along the way!     Thanks for reading!    
  • 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.”

  • 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 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!

    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!

    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?
  • An open map?
    Source engine, which is funnily a Quake engine on steroids (a bit of exaggeration but still), inherited the same limitations of its parents in terms of visibility calculations: BSP and PVS. This fact makes Source, as was Quake engine before, more suitable to rooms and hallways separated by portals where the BSP shines in all its glory.
    Inheritably, Source does not like large open maps where the PVS is of considerable size and the over-rendering is a real issue.
    If you work with Source engine, then you already know the importance of optimization in a large, detailed map. Optimization becomes even more imperative when the said map is open.
    What’s an open map? Good question. The word “open” is an umbrella term to denote any map that does not have traditional hallways and corridors that connect indoors to outdoors. The map is mostly large, outdoors with an unbroken skyline; in other words, the same stuff that source engine nightmares are made of in terms of PVS and BSP.
    In a traditional “hallway’d” map with twisted corridors leading to open areas followed by other hallways, and even if you “forgot” to place hints and areaportals, the geometry itself allows the engine to cut visleaves and limit visibility; granted the visleaves’ cuts will be subpar and messy and the PVS will be in excess, but still, the visibility and fps will be relatively under control. A twisted hallway is a remedy to long sight lines after all.
    In an open map, and without hallways and enough geometry to help the engine, the PVS risks to be huge and the whole map could be rendered at once from any point (over-rendering). We are talking here about a severe fps killer and a potential slideshow on a medium to low range computer. Source does not like over-rendering; I repeat, Source does not like over-rendering.
    I believe a screenshot should be welcome at this stage to illustrate an open map. I’ve chosen a nice medium-size map from CSGO to showcase the issue: de_stmarc.

    The shot is taken in Hammer obviously, and you can immediately see that the skybox is one big unbroken body from one edge of the map to the opposite one. This is the classic definition of open map.
    Let’s see this map in 2D view from the side.

    I have highlighted the skybox in blue so you could see the continuous sky body all over the map. Please note that an open map can have varying skybox shapes but I’ve chosen the simple and classic one to showcase my point where it is easier to see and visualize the concept of open map.
    In contrast, a “traditional” map will have several skyboxes, often not connected directly but rather through a system of indoor rooms or hallways, varying in size and shape.
    I will have my map de_forlorn as example here.

    I have also highlighted the skybox in blue and you can easily notice several skyboxes for CT spawn, T spawn, and Mid/bombsites. These skyboxes are not directly connected to each other but the areas related to them are linked on the lower levels through various indoor locations, some vast (like garage, tunnels…) and some small (like lab hallway…).
    If you are not that comfortable with source optimization or feel that certain terms are alien to you, then please read my previous optimization papers and articles before proceeding further in this article (Previous papers can be found here Source Engine Optimization roadmap).
    The necessary tools
    I’m not revealing a secret when I tell you that the same tools used to optimize any map in Source are exactly the same ones used for optimizing an open map. If you were expecting some magical additional tools, I’m sorry to bust your bubble.
    Since the tools are the same (nodraw, func_detail, props, hints, areaportals, occluders…), it is more about how to use them in open maps that makes all the difference.
    So, how to properly optimize an open map? Well, you could always pay me to do so for you (joking…not…maybe…I dunno!!)
    If the above option is off the table, then read on the rest of this article .
    Horizontal hints
    While in a traditional map one might get away without using horizontal hints, it is virtually impossible to skip them (pun intended) in an open map unless you want to witness single digit fps burning your eyes on the screen. They are of utmost importance to negate the "tall visleaves across the map" issue.
    In a traditional map, even if you bypass adding horizontal hints, the damage in fps will mostly be local since the skyboxes are not connected and areas are mostly autonomous in terms of PVS. In case of my map “Forlorn” and referring to the 2D diagram above, if I remove horizontal hints from CT spawn, then only this area will suffer from tall visleaves and over-rendering. Obviously, this is not cool in terms of optimization, but at least the effect will be somehow restricted to this area only.
    In the case of “Stmarc”, you can certainly see that not including horizontal hints will have tall visleaves seen from across the map as the skybox is one unit. The PVS will grow exponentially and the over-rendering will take its toll on the engine.
    Let’s move on to some screenshots and diagrams, shall we.

    This is our glorious open map in side view. The blue lines denote the skybox, the dark grey one is the ground, and the green rectangles represent solid regular world brushes such as building bases for example. The red starfish little-man-with-arms-wide-open is the player. The orange hollow rectangles denote the various visleaves that the engine would probably create in the map (most go from ground level to skybox level and this is what I refer to as “tall visleaf”).
    If you know your optimization, then you certainly remember that BSP relies on “visibility from a region” approach (for a refresher, please consult my papers Demystifying Source Engine Visleaves and Source Engine PVS - A Closer Look. This simply translates to the following: the player is in visleaf A and visleaf A has direct line of sight to visleaves B, C, D, E, F, and G. The PVS for A in this case would be stored as BCDEFG. Once the engine recognizes that the player is in A, and regardless of the exact position in A, it will proceed to render the whole PVS content. Everything in visleaves BCDEFG will be rendered even though the player is at the extreme end of A and has no line of sight to most of this content.
    You can immediately notice the extent of damage you will inflict on your open map if you neglect adding horizontal hints: excess PVS with additional useless content to be rendered at all times.
    Now that we established the importance of these horizontal hints in open maps, the question remains: where shall I put these hints?
    In the diagram above, the most logical places would be on top of the 3 green rectangles.

    We added 3 horizontal hints (H1, H2, H3) on top of the 3 regular brushes in our map (the hint face neatly resting on the top of the regular brush while other faces are textured with “skip”). This will create more visleaves as can be clearly seen in the above diagram, and vvis will take more time to calculate visibility due to the increased number of leaves and portals but this is done for the greater good of humanity your map’s fps.
    Now the player is in visleaf A1 and the PVS is reduced to (sit tight in your chair) A2, A3, A4, B1, B2, C3, C4, D1, E4, F3. On top of the nice result of a greatly reduced PVS (and therefore content to render), keep in mind that leaves A4, B2, C4, D1, E4, and F3 are mostly empty since they are way up touching the skybox.
    Some folks will start complaining and whining: what the hell dude, I don’t have 3 green rectangles in my map; where would I put my hints?? My answer would be: deal with it!!
    Joking aside, open maps will greatly differ in size, shape, geometry, and layout. What you need to do is choose 1 to 5 common height locations in your map where you would implement these hints. Medium maps with mostly uniform building heights can get away with 1 horizontal hint, while complex, large maps with various building heights can do with 4-5 hints.
    If your map has a hill made of displacements that separates 2 parts of the map, then it is also a candidate for horizontal hints. You just need to insert a nodraw regular world brush inside the displacement to be used as support for the horizontal hint (the same technique can be used if you have a big non-enterable hollow building made mostly of func_detail/props/displacements).
    Vertical/corner hints
    These might not come into play as much as their horizontal siblings, however they could see a growing potential use depending on the map’s layout, geometry tightness versus openness.
    I cannot go through all combinations of open maps obviously to show you how to lay vertical and corner hints; what I will do is choose one diagram representing a typical open map scenario with some scattered houses, streets, and surrounding fields. Once you see how I proceed with these hints, it will become a lot easier for you to implement them in your own map regardless of the differing geometry and layout.

    Here’s our typical map viewed from top with grey lines being map borders, green rectangles being houses (solid world brushes), and our tiny red player at the rightmost part of the map. The map has a main street that goes in the middle between houses but the player is not restricted to this path only.
    The diagram below shows how I would proceed with my hints for such setup.

    This is basically what you get when you give a 5-year-old some crayons.
    Seriously though, I just gave each hint a different color so you could discern them on the spot, otherwise it would be hard to tell where each one starts and ends.
    Most of these hints go from one side of the map to the other while going from ground level to skybox top; don’t be afraid of having big hints that cross your entire map.
    Notice that we have both straight vertical hints (shown from above in the diagram obviously) and corner hints; what I did is that I compartmentalized the map so wherever the player is, chances are they will have the least amount of leaves to render in the PVS (this is just a basic hint system and more fine tuning and additions could be done but you get the gist of it).
    To get more details on hint placement, please refer to my paper Hints about Hints - Practical guide on hint brushes placement
    Areaportals
    If your map has enterable buildings, then it is imperative to separate indoors from outdoors using areaportals; this is top priority.
    Make sure to slap an areaportal on each door, doorway, cellar door, window, roof opening, chimney, etc. that leads inside the house in question.
    What about outdoor areaportals? Good call. In an open map without much regular world brushes to maneuver, it could get very tricky to set up an outdoor areaportal system to separate areas. However, you should always strive to have one, even if it is one or two areaportals across the map. The reason is very simple: the view frustum culling effect, which, coupled with hints, will yield the best results in cutting visibility around the map.
    Continuing with our previous diagram, a simple outdoor areaportal system setup could be as follows (top view).

    This setup will make sure that the map is split into 4 areas and whenever you are in one of them as player, the view frustum culling effect will kick in to cull as much detail as possible from the other areas.
    Let me show you the setup from a side view to make it easier to visualize.

    This is the same areaportal that was closest to the player in the top down view diagram but this time viewed from the side. Unlike hints where it’s fine to have one big hint going across the map, for areaportals, it is best to have several smaller ones that tightly follow the contour of the geometry eventually forming one big areaportal system.
    Another possibility for outdoor areaportal system is to have a combination of vertical and horizontal (yes horizontal) areaportals.
    If your map is a village for example with a highly detailed central square where most of the action takes place, a potential system could be made of several vertical areaportals that sit in every entrance to the square from adjacent streets, and a horizontal areaportal that “seals” the area and works as a “roof”.
    For a practical guide on areaportals placement, please check out my article Practical guide on areaportals placement
    Props fade distance
    This is a really, really important tool when optimizing large open maps. In case you got distracted while I was making the announcement, I’ll go again: props fading is definitely vital when tackling open maps optimization.
    What you need to do is to set an aggressive fade distance for all trivial props that do not contribute to gameplay. Players will look closely at how detailed your map is when they check it out solo on the first run; however, when the action starts and the round is underway, adrenaline, focus, and tunnel vision kick in, and all the details become a blur.
    During an intense firefight, players will not notice small props and details up close, let alone at a distance. We need to use this to our advantage to fade props thus releasing engine overhead; a faded prop is not rendered anymore and engine resources will be freed and allocated elsewhere.
    Your map geometry will dictate the proper fade distances, but as a rough guideline, small props could have a fade distance anywhere from 800 to 1200 units (flower pot on a window sill, small bucket at the back door, a bottle on the sidewalk…), while medium props could do with 1400-1800 range (a shrub, a power box on the wall, an antenna on the roof, wood plank, gutter pipe, fire hydrant…).
    Be very careful though not to prematurely fade critical props used for cover or game tactics (car in the middle of the street, sandbags, stack of crates, dumpster on the sidewalk…).
    Cheap assets
    Many people forget about this technique which is more than needed when it comes to open maps that tend to have larger average PVS than traditional maps.
    I showcased in a previous article of mine the fps cost of cheap and expensive assets (Source FPS Cost of Cheap and Expensive Assets).
    Get in the habit of using the low-poly model version as well as the cheap texture version in the distant non-playable areas and the high unreachable areas where players won’t have much of close contact with the environment. Potential candidates could include a distant field, the unreachable opposite bank of a river, a garden behind hedges/walls, high rooftops, the 3D sky…).
    Fog/Far-z clip plane
    This technique, when correctly used, can provide a big boost to your frame rate as parts of the world beyond the opaque fog won’t be rendered at all.
    For this technique to work properly, your map should have a foggy/rainy/stormy/dusty/hazy/night setting (use as applicable) where a fully opaque fog won’t appear out of place. Obviously, if your map takes place in a sunny and clear day, this technique won’t work much and it will look inappropriate.
    Using this is simple: For example, if your map is set in a rainy and foggy day, you just need to set the fog end distance while having its density set to 1. You will then set the far-z clip plane to something slightly higher than the maximum fog distance (if the fog end distance is 8000 units for example, the far-z could be set to 8200).
    3D skybox
    This is another good technique to reduce engine overhead and the cost of rendering.  
    It is true that the 3D sky is used to expand the limits of your level and decorate its surrounding, however, since it is built at 1/16 scale (and expanded in-game), it is also a nice way to decrease rendering costs. Use this to your own advantage and relocate assets in the non-playable areas with limited player interaction to the 3D sky.
    One thing to keep in mind though, the 3D sky’s visleaf is rendered at all times on top of the PVS in the playable area. Do not go overboard and make an extra complex, highly expensive 3D sky or you would be defeating the purpose of this optimization technique.
    Occluders
    You thought I forgot about occluders? Not a chance as these are the big guns when it comes to large open maps with little world brushes to use for other optimization techniques.
    Let’s clear one thing first; if your map is made mostly of brushwork and displacements with little to no props, then there is absolutely no need to resort to occluders as they’d be totally useless in this case. Only when the map is loaded with models and props in an open setup with little regular world brushes that occluders come to play in force.
    To place occluders, you would search for areas where these occluders could make the most impact (low fps, high traffic, props abundance) since they run in real time and are expensive, otherwise their cost would outweigh their benefit in terms of frame rate variation.
    Remember that occluders rely on the player’s position and field of view relative to the occluder to calculate what gets culled. You need to place them in a way to maximize the number of props to be culled behind them when the player stands in front of these occluders.
    Let’s see some examples.

    We go back to our famous top down diagram; the occluder is dark blue placed on the left wall of the large house while the little black stars represent various props and models. The 2 diagonal black lines denote the player’s FOV relative to the occluder. Anything behind the occluder and within the view frustum will be culled.
    That’s nice; we are able to cull 4 props but is it enough? It is not optimal as we can still do better. What if we move the occluder to the right wall of the house?

    Much better if you ask me. 5 additional props were added to the culling process meaning less overhead and fewer resources to render for the engine. That is why I said earlier it is all about maximizing the impact of the occluder by placing it in a way relative to the player’s position that maximizes the number of culled models.
    Here’s another example (still top down view).

    The player has moved to the middle of the central street, and beyond that L-shaped house is an open field with a lot of props scattered around. One way to implement occluders is as showcased in the above diagram. Notice how I arranged 2 perpendicular occluders along the walls for the maximum occlusion effect as all of these props in the field are not rendered from that player location.
    Another way to arrange occluders in this case would be diagonally across the L-shaped house (split into 2 or 3 occluders if needed to accommodate the nearby geometry; they can be floating without the need to seal an area).
    If you’re feeling brave enough (you should be after reaching this far in this article), you could also add an extra occluder along the wall of the house to the left of the L-shaped house to further enhance the view frustum occlusion effect and cover more props in the field.
    The most common places to add occluders in open maps include a displacement hill that separates parts of the map, a hedge that stands between a street and a field full of props, a floating wall between a house garden and the street, the walls of a large house, the walls of a tall building, a ceiling when it separates multiple levels…
    To read more about occluders placement and cost, please consult my article Practical guide on occluders placement
    In conclusion
    The foundation of optimization in Source engine will be the same whether it is a traditional map or an open one. You will heavily rely on func_detail, nodraw, displacement, props… to achieve your goals but it is the way you use these tools in an open map that makes all the difference.
    One might get away with being a bit sloppy with optimization in a traditional map, however, make no mistake that an open map won’t be any forgiving if you decide to skip a beat in your optimization system.
    Talking about different open maps and formulating varying optimization systems for them could fill articles; I hope this article has shed enough light on the open maps optimization approach to let you easily design a system for your own map.
  • Creative Airlocking: streaming in action games
    This article will discuss the loading and unloading of areas in linear single-player action titles, and look at contemporary examples of how the best games mask these so they appear seamless.
    Background
    When designing levels, Level Designers and Environment Artists must consider that their assets all have to fit within memory at once. While older action games like Wolfenstein 3-D and Doom would load the entire level with a Loading Screen at the start of each map, games like Half-Life started a trend of loading smaller sections gradually so they could squeeze in more detail and also provide a more seamless experience for players, making the game feel like one long adventure.
    At the time, going from one space to the next in Half-Life resulted in a seconds-long hitch with the word “Loading” on screen. There was no warning that it was going to happen, although Valve’s Level Designers oftenplaced these level transitions in smart places; usually down-time between combat and in a natural chokepoint. In later years, with faster computers, these load times decreased and are now almost seamless.

    Half-Life displays a small loading message when transitioning between levels.
    Currently, blockbuster series like Gears of War and Uncharted provide truly seamless transitions. After one long initial load for a new chapter with a completely new location (with new art) – sometimes masked behind a pre-rendered movie – “buffer” Streaming Sections are used, in which the previous area is unloaded, and the next loaded, on the fly. Since a lot of the globally-used entities are already loaded, and the environment is usually the same, assets can be shared, which can reduce these transition load times to much less than the initial level load.
    Essentially, these games take the smaller loading bar/screen of a more continuously-laid-out game like Half-Life, Portal 2 or Fallout 4 and make the player spend that time in the game world. If done creatively, players won’t even notice it. They might even enjoy the down-time if it’s well-paced, like The Last of Us where it can be spent on a thought-provoking puzzle or with the characters discussing something interesting.
    Overview
    Most action games budget out large areas, and then connect those with these smaller Streaming Sections.
     

    Section (A) is a huge space with lots of combat, Section (C) is another. Players in Streaming Section (B) can’t see into both (A) and (C) at once. Section (B) is where Section (A) is dropped from memory and (C) starts to load in. Section (A) being dropped shouldn’t happen in view of the player, and unless the game supports backtracking it is wise to place a back-gate to stop players returning, for maximum efficiency. As soon as Section (A) has been dropped, Section (C) can start loading in. It must have been loaded by the time the player exits Section (B), so it is also wise to front-gate players in case they rush through.
    The best way to think of a Streaming Section is as an airlock; the “door” behind the player is locked, the next area is loaded, and the “door” ahead opens. Ideally, these sections aren’t literal airlocks but instead nicely-disguised puzzles or narrative spaces between the action.
    Back-gating, and Unloading
    Back-gating, as the term suggests, is when the player is prevented from returning to a previous area. The ‘gate’ behind them is closed, in a lot of cases locked. This doesn’t have to be a literal gate or door, though. A ceiling can collapse causing debris to block the path behind the player, the player can fall through the floor and not be able to climb back up, they can pass through a one-way portal and not get back.
    Back-gating after entering the Streaming Section is usually done around a corner where the player can’t see Section (A) being unloaded.
    One-way animations are the main manifestation of these in modern action titles. Think of how many doorways your player character has held open, only to have it collapse behind them. The level section behind that door is now being unloaded, to make space in memory for the next large section. In co-op games, these animated interactions are a great way to bring players back together so that Player 2 isn’t left behind, only to fall through the world, in the section that is just about to be unloaded!

    The Last of Us has a huge variety of bespoke, painstakingly-animated back-gates.
    A cut-scene can also serve as a good back-gate, as long as it makes sense in the context and/or story so as to not feel tacked on, and is within development budget!
    One-way drop-downs are also a great and less flow-breaking back-gate. If the L-shaped area just before the drop-down can be kept in memory, as soon as the player drops down a ledge they can never climb back up, the previous area can be unloaded. The only down-sides to this softer back-gate are that they can feel contrived unless the game’s art and world can support it (terrain and collapsed structures are great for this), and that co-op players may have to be teleported to the dropping player so that they don’t fall through the world when Section (A) is unloaded.
    Slowing the player down, and Loading
    As Streaming Sections are usually connectors between two larger areas, they naturally make for slower-paced breaks in the action. Since Section (C) is being loaded in, slowing the player down in (B) – either literally as with Gears of War’s infamous forced walks or cerebrally with light puzzle gameplay – can be more efficient and interesting than just making a large footprint which has to cater for a player, say, sprinting for 30 seconds.

    Even when rushed, this plank puzzle in The Last of Us takes time and offers a nice respite.
    “Popcorn” encounters with just 1-2 enemies can be a good trick to allow loading to finish and slow players down and prevent them from simply rushing through a short Streaming Section. They also keep players on their toes and vary the flow from, for example, combat to puzzle to combat.
    Interactive Objects such as the slow-turning valves in Killzone 2 and the Gears of War games can also buy some loading time, as can environmental obstacles such as jumps or mantles or animations where the player’s buddy looks around for, and then finds, a ladder to kick down for the player to climb (also a good front-gate).

    Interactions like the valve in Gears of War slows players down and can also act as a front-gate.
    These approaches can also be combined in ways that fit the feel of the game, such as a Grub locking the player in a room and flooding it with frightening enemies in the first Gears of War game.
    Batman Arkham Asylum does a great job with additional ‘softer’ methods of slowing players down by playing a captivating well-acted taunt on a monitor from The Joker, or by encouraging exploration with The Riddler’s location-specific riddles or any number of collectibles.
    Front-gating, and Loaded
    As with Back-gates, front-gates are quite self-explanatory – the exit to the area the player is currently in is locked until certain conditions, such as all the enemies in the room being dead or the next area having loaded in, are met. Again, this doesn’t have to be a literal gate or door, just an obstacle in the world that can change its state from closed and locked to open.
    A lot of games from the Call of Duty series to Killzone 2 to The Last of Us extensively use friendly characters to unblock a front-gate; chain-link fences are cut through, doors are kicked open, wooden beams are lifted. New waves of enemies can also open a front-gate for the player and offer the bonus in that noisy, gun-firing AI attract players, like carrots on a stick, to the newly-opened exit. Many action games have excellent examples of enemies blow-torching open a door to get in or a huge monster bursting in through a wall; not only are these cool enemy entrances, but oftentimes their new unorthodox entrance-ways become cool exits, sign-posted by their un-gating event.

    Previously-locked doors in Halo often flash and make noise when opened by new enemies.
    Not all games front-gate the exits of their Streaming Sections because the time needed to load a Section (C) can usually be accurately gauged, and the acceptable fallback is a slight hitch. However, front-gates do provide that extra failsafe to ensure the next area is loaded before leaving a Streaming Section – in this case, a player with a scratched disk or corrupted file could see out of the world, at best, or get stuck or fall out of the world, at worst (though it could be argued someone with a scratch or corrupted files might see worse issues regardless).
    The biggest issue here is that front-gates need to fit the game or the level art – neat doorways or bottlenecks aren’t always possible. The other big issue is repetition; if a specific door interaction animation is always used, the game needs to provide a lot of variety in that animation!
    One trick that can be used to alleviate repetition, however, is if the front-gate is out of sight near the end of the Streaming Section (A). A check can be done to see if Section (C) has loaded, and if it has, the door can potentially be pre-opened saving the player another potentially-repetitive interaction but also holding as a true front-gate if a player does rush through.
    Batman Arkham Asylum had an interesting front-gate in the penitentiary sections; a security camera scanned Batman once before opening the door. Given the backtracking-heavy structure of the game, when racing through at full pelt, if the next area had not finished loading, the camera would loop the camera’s scanning animation. This is a great compromise because the camera scan completely fits the fiction of the world, and an extra scan animation would probably go unnoticed by many players.

    Batman Arkham Asylum’s Penitentiary’s doors only open when loading is complete.
    Conclusion
    In most linear action games, keeping the player immersed in the world is preferable to seeing a loading screen. If developers can create interesting activities, take advantage of slower pacing through narrative, or just make smart use of assets and an interesting space to traverse, Streaming Sections can be part of the world and not feel like generic winding corridors that stand out even to uninitiated players as padding.

  • This article is the first installment in a three-part article that looks at the considerations for creating a single-player combat space, using a walkthrough of the first battle in ‘Killzone Mercenary’ as a working example.
    Creating a Single-Player Combat Space Part 1
    This article will explain how to create a combat space for a single-player campaign, using my work on ‘Killzone Mercenary’ (hereon referred to as KZM) as an example.  There is already a fair amount of literature on the different methods you can use for creating a combat encounter, but I felt that none of it really discussed how to arrange the layout in closer detail, nor did they discuss where the different elements were appropriate.  In my early work I tried to jam in all the concepts for encounter design without fully understanding how they affected the player’s experience.  As strange as it sounds, I discovered there were times when it was better to restrict the number of elements being used to provide a much more focused and coherent experience; sometimes less is more. I will take you through an example to explain what I mean and how this can be the case.
    I will use the very first combat arena in KZM as it’s a small encounter where I can explain in depth what goes into even the most basic combat space. This encounter is a fight against assault troopers who are trying to stop the player from escaping the building and reaching the objective building; the ‘Halls of Justice’. I designed bigger encounters that featured many flanking opportunities and complex circular navigability but focusing on a simple encounter allows me to explain certain techniques in detail and where I purposely removed some elements to balance the difficulty and give the player different experiences.
    First of all I will explain two important aspects that must be considered for combat creation; AI metrics and weapon choice. I will then take you through a step by step walkthrough of this first encounter explaining in detail the reasons how it was designed and constructed for optimum player experience.
    Metrics
    The design mantra ‘form follows function’ should be the basis when creating an arena layout; that is that the arrangement of geometry should derive from its purpose. The arrangement should support the function not only of the style of experience you want to create (is it a tight corridor section with close quarters combat or an open space with multiple routes and options, for example) but it should also support the main element that makes up the combat encounter; the enemy AI.
    When considering the layout for the AI or non-player characters (NPCs) that will populate your environment you have to consider their metrics. These are the numerical values for how the NPCs move around and use the environment and the differences between various NPC enemy classes. This isn’t something people tend to talk about and so it can be easily forgotten or missed, yet it directly affects how your enemies will move and react.
    For example, in KZM the standard enemy NPC class were the Assault Troopers. These soldiers could be given patrols and animations to perform whilst they were in an ‘unalerted’ state, just like every other enemy class.  However, when they were in an alerted state their behavior changed so that they used cover points to move around the combat space. The maximum distance between cover points that an assault trooper would move was 10 meters. This meant that any cover point that was further away would not be considered, so we needed to make sure when creating combat spaces which used assault troopers that there were enough cover islands so they could move around. If there weren’t, the assault troopers would just stay in the same spot and could risk looking less intelligent.
    The assault troopers also tried to maintain a distance of 15m whilst they were trading shots with the player. The behavior was that if the player got closer than this range, but not so close that they were in melee combat distance (5m), the assault troopers would retreat to this mid-range distance of 15m. They would also never choose a cover position that was closer than 15m to the player, so when we created combat spaces we had to make sure that there was enough variety of cover positions in the >15m range.
    For the production of KZM we used the ‘Killzone 3’ engine and modified it for the PS Vita. In ‘Killzone 3’ the assault troopers picked their cover within a range that was further than 25m from the player, but we discovered that this was too great a distance for the enemy to still be clear and readable on the PS Vita screen. In our modified version of the KZ engine we had to reduce the combat distance to 15m, which meant that the original combat spaces we had created using the ‘Killzone 3’ metrics also needed adjusting in order for the NPCs to still work. It is an unfortunate truth that the game metrics, be it for the AI or otherwise, can change within a game’s development, which means that your combat arenas will also need to be adjusted.
    Weapon Consideration
    The metrics for both the player and enemy weapons were also considered. As this is the start of the game we can be more certain that the player is using the default starting weapons, at least on their first playthrough, before they have earned enough credits to buy a new arsenal. Therefore, the combat distances of enemy placement were considered to be comfortably within range for the player’s assault rifle.
    The enemy assault trooper archetype used assault rifles that were balanced to have a short range of <10m, and a long range of >20m. This meant that their behavior was to try and keep the player within these ranges and would thus move around the environment to try and maintain this. This was important to consider when building the environment so we could determine the amount of movement the troopers were likely to perform. This is important for balancing difficulty as a moving target is harder to hit.
    Foreshadowing
    As this was the opening of the game, we wanted to make it compelling in order to grasp and hold the player’s attention; we wanted to start with a bang. If the first lot of encounters in the game only included assault troopers with nothing else to differentiate them it may not have been so compelling. Therefore, we decided to include a significant Killzone enemy vehicle; the Helghast Dropship.  Of course it would have been far too difficult to fight a Dropship at this point in the game, so instead it was used as an impressive introduction of enemies into the arena using the rappel ropes from the ship itself.
    Using the Dropship at the end of the encounter, it was important to foreshadow its existence prior to its introduction. The level’s opening cut scene introduces the buddy character, Ivanov, and the narrative that he and the player are infiltrating the building whilst trying to avoid the searching eye of the Dropship.

    The foreshadowing of the Helghast Dropship
    Once the player has control they make their way up a flight of stairs learning how the movement works and feels whilst being in a safe environment. Once at the top of the stairs they enter through a door where they are introduced to the new melee attack which utilizes the touch screen on the PS Vita.
    First Wave
    After a successful melee attack the player enters through the door to the first combat area. The composition shows the exit of the arena in the top left third of the frame.  Central to the player’s view is where the first pair of enemies enter from, ensuring that their arrival is not missed.

    The exit to the arena is in the top left section of the opening composition
    Starting on the level above, the two assault troopers vault down into the gameplay space, to give their presence a more dramatic opening than merely walking in through a door. Their animation and movement also ensures that they catch the player’s eye if they aren’t looking in the desired direction. These vault down animations were 4m high, the standard height for a room in KZM, which meant this was a metric we had for the balcony and floor above.

    Two assault troopers drop into the environment from the level above
    Once the assault troopers had landed in the arena they became a lot less mobile than their standard behavior so that they were easier to shoot because, as previously mentioned, a moving target is harder to hit.  As this is the very first section of combat the player encounters in the game it was important to ensure that it was easy to get to grips with.
    None of the enemies were waypoint/navmesh restricted to certain areas in order to limit their movement as this could potentially lead to NPCs not behaving correctly under differing circumstances. In fact, there were only a very select few instances where we waypoint/navmesh restricted any characters in the whole of KZM; we instead crafted the environments to support the behavior we wanted from the NPCs. This was important for consistency; if you restrict areas and zones for the AI then they won’t behave consistently with what the player has learnt. This would lead to the player not being able to predict their behavior and therefore won’t be able to plan how to attack effectively.
    Here, in this first section, the two assault troopers took cover at two upright pillars of high cover and an overturned sofa of low cover. They didn’t tend to venture further into the environment unless the player had for some reason retreated to the edges of the level. The reason they wouldn’t move and advance on, or flank the player was because the other cover options in front of them were within 15m of where the player was likely to be stood. This caused them to be more static and thus easier targets to allow the player to get to grips with the shooting mechanics.
    I also chose to mainly use higher cover here so that when the enemies lean out of cover their shooting positions allowed the player to shoot their full body, which was a bigger target than when they poked their heads over the top of the low cover positions.
    Low cover positions are great for seeing the enemies move around and change their positions, as the tops of their helmets are visible over the top of the cover. Enemies are much harder to track when they use high cover as it breaks line of sight to them, so this is usually the harder option. However, as they have restricted cover positions and weren’t moving around in this specific situation, it was the best option to use for less difficulty.
    First Combat Front
    A ‘front’ is the perceived line or boundary that faces the enemy and is the nearest position which combat should be engaged from. The ‘fronts’ used here create boundaries between the two sides; a front for the player and the buddy character and an opposing front for the two assault troopers. This was the simplest setup to start the player off with and it only required two sets of cover points as I didn’t want to encourage the enemy to flank the player at this stage. This section of the encounter only needed these few pieces of cover (in the image below) in order to work and the other pieces of cover were actually for further waves of combat.

    The two fronts and the cover setups providing it
    It’s also worth noting that the cover object which the buddy character crouches behind is positioned further forward than the arrangement of cover that the player is drawn to. This is so that the buddy character is in the player’s view so they always see the buddy’s actions and involvement. It wouldn’t be optimal to have a buddy NPC that the player rarely saw. The buddy is also kept near to the player in order to maintain a close relationship and the feeling of being a team. Empathy is directly related to proximity between characters, so if the buddy was further away from the player they would experience a much more detached feeling towards them.

  • A new question?
    After successfully solving the eternal mystery of func_detail vs. displacement in my last article (here), I was contacted by the High Council of Source Engine Optimization. Apparently, there seems to be another enigma to be uncovered and a major question to be answered.
    What is the fps cost of cheap and expensive assets in Source engine? Is there a significant difference between the two in terms of frame rate? (that’s 2 questions but I’ll let this one slide)
    The study
    As with the last article, this one is also going to be a short but sweet article; fewer words, more numbers and screenshots. The systematic approach is also going to be very similar: 2 similar test maps where one contains expensive assets while the other has cheap versions of these assets. The assets will be the same and will be located in the same locations in both test maps.
    The recent assets added with the new de_nuke update in CSGO will be the perfect candidates for our study as Valve made most of these in cheap and expensive versions. For props, the expensive version is high-poly models while the cheap one is low-poly. For textures, the expensive version gets a normal map (up to 2), specular map, advanced reflections, detail map, and Phong shading in some cases; the cheap version is basically the diffuse map with the occasional detail map.
    I will record the localized fps in both versions and compare, then draw conclusions that will hopefully answer the High Council’s question(s).
    The testbeds
    The first map to test is the one made of cheap assets. It’s basically a simple map consisting of 4 walls and a floor on which are spread several props and textured blocks at predetermined locations. Textures are mostly concrete while props contain crates, cars, pipes, wires, doors, and vents.

    The fps recorded is 330 fps. The expensive version is exactly the same but with props replaced with their high poly versions and textures swapped with their expensive versions.

    The fps is now 286 fps; interesting. All right, let me call the High Council to relay the news.
    Hold your horses right there. We are men of Science and you know that…yes, yes, I know, one map is not enough to draw conclusions.
    I’m going to take this map and quadruple it, in area and in content, and test again (Nobel prize here I come). The new map will have 4 times the amount of props and textured brushes (the same ones of the initial map cloned into the new areas) as well as having its total area increased fourfold. We start with the cheap version that we will refer to as test map (4x).

    The fps decreased to 279 (from the 330 in the simple cheap map) due to the extra content that the engine has to render. Our main point of concern would still be to compare this version against the expensive one.
    You know the drill by now; we will also create the (4x) expensive version.

    The fps is 229. The decrease in (4x) version is more or less in line with the one in the simple version. Let’s recap in a table for easier viewing.

    As you can see, the fps dropped 44 fps in the simple version and 50 fps in the 4x version, between the cheap and expensive maps respectively.
    We can draw 2 conclusions from the above table:
    There is a significant drop between the cheap and expensive version (44/50fps), and there is also a substantial drop within the same version (51/57fps) when you add much more content that is all visible in the PVS.
    These results can shed some light on the latest update of de_nuke where the overall fps is lower than the rest of the stock maps in CSGO. The high amount of props/details that can be seen/rendered from one location coupled with the expensive assets in the playable area contribute to further decrease in the overall fps in that map (in addition to the open skybox/layout). I have tackled a revised optimization system for de_nuke in a topic of mine last month that can be read here (https://www.mapcore.org/topic/19909-de_nuke-a-revised-optimization-system/)
    As a bonus, I’ll throw in the compile times of the above maps so you can witness the effect of cheap vs. expensive, and the additional content in (4x) versions, on the compile time, especially on vrad since it will mostly be affected by the extra faces in the high poly models and the additional vmt switches in the expensive materials.

    You can clearly see that vrad times increased considerably between the cheap and the expensive versions, as well as within the same version when we quadrupled the area/content.
    Now if you’ll excuse me, I still have a phone call to make; the grand council woman cannot wait any longer.
    The final cost
    Expensive assets bring visual eye candy to the map in hand which is a necessity in today’s ever-growing and continuously pushed graphics boundaries. Relying on low poly models and cheap textures won’t fare well on the visual fidelity front. However, expensive assets come at a cost of taxing the rendering engine and decreasing the overall fps in the map.
    These expensive assets are a requisite if you want your map to shine (pun intended) but one has to be careful not to overuse them. Use them wisely in the playable area and resort to cheap versions when decorating the non-playable areas of the map or any place that the player cannot see up close to discern the difference.

    Good Luck!
  • 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.

      [CS:GO] Shore

      Radix posted a topic in Level Design,

      One of the projects I worked on after I made de_austria.

      Yeah, I know the timing is really bad (CS2!), but can't change it... 🙁

      In general a lot went wrong during this project. Had a lot of problems with the layout, but I think I found a good compromise in the end. Also learned many new things. Maybe I would even be ready to create a really good map now after all, but I think that it's gonna be the final one. I really like making maps, but it has become too time consuming over the years for just being a hobby. Unfortunately I never managed to get a job in the games industry. So that's it. I hope it's a worthy ending of 20 years of making maps for me. 🙂

      Shore is a bomb defusal map for CS:GO that takes place on Lofoten Islands, Norway. (Also have a Hostage version of this that works well imo)

      I took some inspiration from this place in Norway:
