ShaderCompile

Standalone shadercompile, that doesn't depend on valve libraries and supports x64. Also removes dependencies on external tools (no perl or DxSdk). This fork also makes use of old include file format with default constructor and lowercase indexes. No need to replace cshader.h

Usage

ShaderCompile.exe [OPTIONS] -ver n -shaderdir src_dir shader.fxc

Options

-ver ARG                       Sets shader version, required
-shaderpath ARG                Base path for shaders, required
-crc                           Calculate crc for shader
-dynamic                       Generate only header
-force                         Skip crc check during compilation
-threads ARG                   Number of threads used, defaults to core count

-h, -help                      Shows help
-verbose                       Verbose file cache and final shader info
-verbose2                      Verbose compile commands
-verbose_preprocessor          Enables preprocessor debug printing

-disable-optimization, /Od     Disables shader optimization
-disable-preshader, /Op        Disables preshader generation
-no-flow-control, /Gfa         Directs the compiler to not use flow-control constructs where possible
-prefer-flow-control, /Gfp     Directs the compiler to use flow-control constructs where possible
-partial-precision, /Gpp       Compiles shader with partial precission
-no-validation, /Vd            Skips shader validation

Shader model version support

All shader models starting from PS2.b/VS2.0

Valid options for -ver

20          ps2b/vs20
30          ps30/vs30

Getting started

This assumes you have "clean" Source SDK2013 project.

1. In game_shader_dx9_base.vpc replace $AdditionalIncludeDirectories "$BASE;fxctmp9;vshtmp9;" with $AdditionalIncludeDirectories "$BASE;include" , shader headers will be now located in more sensible place
2. Place ShaderCompile.exe and process_shaders.ps1 to devtools/bin folder where vpc.exe is located
3. Replace buildshaders.bat with one from this repo
4. In buildsdkshaders.bat, remove from all commands -dx9_30 so

   %BUILD_SHADER% stdshader_dx9_30 -game %GAMEDIR% -source %SOURCEDIR% -dx9_30 -force30 

   looks like

   %BUILD_SHADER% stdshader_dx9_30 -game %GAMEDIR% -source %SOURCEDIR% -force30

5. Optionally remove all perl scripts for compiling shaders from devtools/bin, as they will be never used again
