No

URP/Lit and URP/Simple Lit and shaders based on these do not render in WebGL Player

-

Reproduction steps:
1. Open the attached “IN-107736.zip” project
2. Go to File > Build Profiles
3. Switch the platform to Web
4. Build and Run the project for WebGL
5. Observe the Player in the browser

Expected result: Everything is rendered correctly with shaders, like in the Editor
Actual result: Majority of the Scene is rendered black/gray and errors are thrown in the Developer Console

Reproducible with: 6000.0.54f1, 6000.1.12f1, 6000.2.0b10
Couldn’t test with: 2022.3.63f1 (Could not downgrade), 6000.3.0a2 (Unfixable Behavior package errors)

Reproducible on: Windows 10 (user reported), Windows 11
Not reproducible on: no other environment tested

Notes:
- Does not reproduce in the Editor or Windows build
- Significant performance drop is also observed in WebGL builds
- Could not reproduce on a new project
- “InvalidOperationException: The LinkedList node already belongs to a LinkedList.” and “ArgumentException: The state of the provided MeshGenerationNode is invalid (entry is null).” errors are visible in the Developer Console

  1. Resolution Note:

    Chrome currently has some WebGL bugs which cause issue with Forward+ rendering with the Additional Lights Cast Shadows option. This is due to a bug in Chrome's GLSL shader compiler on Windows. Google is aware of the issue. For now, it is recomended to use the Forward instead of Forward+ renderer on the URP Renderer settings, or to disable Additional Light Cast Shadows option in the URP pipeline asset settings.
