Graphics.RenderPrimitives does not work when using Surface Shaders

Unity: DirectX11

Fixed

2023.3.X

2023.2.X

2023.2.0a20 onwards

2022.3.X

2022.3.8f1 onwards

2023.1.X

2023.1.9f1 onwards

The emulation path for providing vertexbuffers for draws via api that does not provide vertexbuffers handles instancecount correctly. The shader itself should be changed into #if !defined(SHADER_TARGET_SURFACE_ANALYSIS) instead of D3D11 specific tag. That makes it work on all platforms.

Graphics: Surface shader path has correct parameters set when emulating vertexbuffers.

How to reproduce:
1. Open the “IN-54270_repro“ project
2. Open the “SampleScene“
3. Enter Play Mode

Expected result: “ProceduralSurface“ and “ProceduralRender“ GameObjects look the same
Actual result: “ProceduralSurface“ GameIObject looks incomplete

Reproducible with: 2021.3.30f1, 2021.3.31f1, 2022.3.11f1, 2023.1.16f1, 2023.2.0b13, 2023.3.0a9
Not reproducible with: 2021.3.29f1

Reproducible on: Windows 10
Not reproducible on: macOS

Note: macOS reproduces a different issue (could be related)
