Compile status: 
November 5, 2004: Valve releases Source Engine's SDK into public. People started making mods for the bestselling game, Half-Life 2. Years have passed and now we're stuck with Source SDK 2013, being the last publicly released and outdated since release (based on Orange box's Source SDK, while Portal 2 branch is already finished) SDK. Strata Source team formed to fix this, tried to be community's hero, but failed, because Valve's Licensing doesn't allow making licensed SDK to be released publicly. It's time to do something about it.
[!NOTE] Just saying, I am not trying to demean Strata Source and so sorry if that sounded mean.
Introducing SourceDEFUN: Based on Alien Swarm SDK, forked off Deferred repo. It promises to be as modern as the SDK's limitations allow it to be. DEFUN means a function in LISP's programming language, referring to Source Engine's roots: from Quake, to GoldSRC, to Source itself.
Quake >>> GoldSRC >>> Source >> Alien Swarm > Deferred > SourceDEFUN
Special thanks to...
Kristjan Skutta - for creating Alien Swarm Deferred!
maksw2 - for being the first contributor and helping with compilation errors!
Features (sorted by most needed ones):
- [x] Deferred lighting (from Alien Swarm Deferred)
- [x] PBR (Physically based Rendering)
- [ ] Linux Support
- [ ] DXVK Support (man i wish it was possible to support Vulkan instead of DXVK)
- [ ] First Person Camera, ported to Alien Swarm branch
- [ ] Increased map size (yes it's possible i checked however i'm not sure if that'll work) at the probable cost of decreased precision (won't be visible anyway)
- [ ] Chromium Embedded Framework
- [ ] Menu
- [ ] CSS Theme
- [ ] JS execution
- [ ] Ambient Occlusion
- [ ] Sandboxed Python Support (like VScript!)
- [ ] SourceDEFUN Mod Installer (does moving mod to sourcemods for you and more stuff)
...and probably more soon!
You can watch the progress here.
Building
Windows:
[!WARNING] Even though the solution was upgraded to support VS2022, it will be deprecated soon in favor of CMake.
To compile the shaders you must install Strawberry Perl, then execute ./materialsystem/swarmshaders/buildshaders.bat
Linux:
Make sure to install these packages through your package manager:
cmake make perl (This is just a wild guess)
UNFINISHED.
[!NOTE] macOS won't be supported anymore because there is no reason: if you want to play anyway, just switch to Linux.
Information
Cannot do anything?
This might be happening because of my latest ruleset. I don't really know how to set these up, so if you cannot open an issue/pr, the contact me at discussions!
Legacy README.txt file
The following new directories are required for the deferred implementation to work:
materialsystem/
game/client/deferred/
game/server/deferred/
game/shared/deferred/
+ shader compiling:
dx9sdk/
devtools/
A few changes in standard files have to be made first too.
All of them have comments like this:
// @Deferred - Biohazard
affected files that require updating (not all changes have a comment since there are too many, use diff):
game/client/cdll_client_int.cpp
game/client/viewrender.h
game/client/viewrender.cpp
game/client/flashlighteffect.h
game/client/flashlighteffect.cpp
game/server/gameinterface.cpp
public/renderparm.h
Most core tweaks and changes can be done in the following headers:
materialsystem/swarmshaders/deferred_global_common.h
game/client/deferred/deferred_client_common.h
game/shared/deferred/deferred_shared_common.h
game/server/deferred/deferred_server_common.h
SECRET: Impossible things that would be cool to have
- Mapbase support
- Upgraded VRAD that makes realistic lightmaps
- Native Vulkan (Not DXVK) support
- Material System that can use PNG/JPG instead of VTF
- Independent Texture sizes that doesn't fit into powers of 2
- Subsurface Scattering
- Exporting into a standalone game (this will require leaked Source Engine which shouldn't be used for commercial purposes)
