Shader starts acting unexpectedly when SV_primitiveID is used in a Hull/Domain Shader
How to reproduce:
- Open the “SV_PrimitiveIDBuggy.zip“ project
- Open the “bug_primitiveid” Scene
- Select the “Assets/ExampleCode/Unlit_NewUnlitShader.mat“
- In the Inspector, increase the “Index Value“ from 0 to 1
- Observe the Scene view
Actual result: Shader triangles form into a cube regardless of the SV_PrimitiveID value
Expected result: Shader triangles displaced by the value of SV_PrimitiveID
Reproducible in: 2023.1.0a1, 6000.0.64f1, 6000.3.1f1, 6000.4.0b1, 6000.5.0a3
