Support for Ray Tracing shaders (.rgen, .rchit, etc.) in ShaderCompiler.Build

[fidarit]

Hello!

I'm trying to use XenoAtom.ShaderCompiler.Build to compile ray tracing shaders, but the compiler doesn't seem to recognize or process files with ray tracing extensions:

• Ray-Generation (.rgen)
• Ray-Closest-Hit (.rchit)
• Ray-Any-Hit (.rahit)
• Ray-Miss (.rmiss)
• Ray-Intersection (.rint)

Attempted Workaround

I tried to force compilation by adding a custom ItemGroup in my .csproj file:

<ItemGroup>
  <ShaderCompile Include="assets\shaders\RayTracing*.*">
    <ShaderCompilerOption_source_language>glsl</ShaderCompilerOption_source_language>
    <ShaderCompilerOption_target_env>vulkan1.2</ShaderCompilerOption_target_env>
  </ShaderCompile>
</ItemGroup>

This correctly sets the source language and target environment, but compilation fails with the following error:

error: Stage not specified by #pragma or not inferred from file extension

Expected Behavior

• Automatic recognition of RT stages.
• Or a way to specify the stage via MSBuild properties.

Actual Behavior

Files are either ignored or fail with the stage inference error.

Additional Context

Is there a way to configure the compiler to support these? For example, custom MSBuild props/targets or additional flags? If not supported yet, could this be added as a feature?

Thanks in advance for your help!

Update: I managed to compile all ray tracing shaders except .rint (intersection).

For .rgen, .rchit, .rahit, .rmiss – adding #pragma shader_stage(raygen / closest / miss) works fine.
But for .rint, with #pragma shader_stage(intersection), I get:

error: '#pragma': invalid stage for 'shader_stage' #pragma: 'intersection'

I may be entering the wrong value, I will be glad if you tell me the correct option.

Thanks!
