Repro steps:
- create new project with HDRP 3D template
- open Project Settings
- add OpenGL Core to the Rendering API list (no need to switch rendering API)
- notice the console has errors now:
Shader error in 'StageSetupSegment': syntax error: unexpected token '#' at kernel Main at (12)/Library/PackageCache/com.unity.render-pipelines.high-definition@15.0.4/Runtime/ShaderLibrary/ShaderVariablesFunctions.hlsl(115) (on glcore)
Note: if you add OpenGLES as well, there will be even more errors and warnings:
Shader warning in 'GenSdfRayMap': Buffer count exceeding default GL_MAX_SHADER_STORAGE_BUFFER_BINDINGS. Shader might not work on all hw. Consider combining separate buffers into one containing struct elements. at kernel ClearTexturesAndBuffers (on gles3)
Reproducible in: 2023.1.0a1, 2023.2.0a7, 2023.1.0b8
Cannot repro in 2022.2.12f1 or 2022.2.0f1
Likely regressed version: 2023.1.0a1
