Shader throws compilation errors when SV_GroupIndex is used in ComputeShader
How to reproduce:
1. Open the attached project “GroupIndexBug”
2. Observe the Console
Expected result: There are no errors and the Shader is compiled correctly
Actual result: There are three errors preventing the Shader from compiling
Reproducible with: 2021.3.35f1, 2022.3.19f1, 2023.2.9f1, 2023.3.0b6
Reproducible on: Windows 11 Pro
Not reproducible on: No other environment tested
Notes:
-Sometimes for the error to appear in the Console, you need to reimport the “IN-67932_RayCheckTessedQuad” Asset
-Commenting out line 12 in the “IN-67932_RayCheckTessedQuad” Asset solves the problem
Full errors:
-Shader Compiler IPC Exception: Terminating shader compiler process
-Shader compiler: Compile IN-67932_RayCheckTessedQuad.compute - TessedQuadRayLength: Internal error communicating with the shader compiler process. Please report a bug including this shader and the editor log. Error code 0x80000004 (Not connected).
