This is my simple material. I have two commits, one with 20171.17f1 and one after updating it. The material is also very simple. After upgrading it nothing is rendered anymore.
The Inspectory still shows the same expected values
The migration is from 9.0.0-preview.72 to 10.2.2 and there is nothing in particular special mentioned in the upgrade guideline

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@10.2/manual/upgrade-guide-7-2-0.html
Any ideas on what has changed with this major release or with the shown material shader graph?
These are the git changes I can see that stem from the upgrade
This is a bit annoying for a release where I don’t see any breaking changes announced.
This is the ShaderGraph Shader after the update.

btw: The Havok Visual Debugger sitll shows the correct MeshCollider so I am pretty sure the shader, Hybrid Renderer or something else is broken here and not the mesh:
The Frame Debugger also shows no pass for this mesh.
These are the Camera Settings

Thanks to @eizenhorn who brought me (likely unknowingly ) to the right direction. The setting that breaks the rendering is the SRP Batcher:

Turning it off causes the mesh to be rendered again:
Same problem, same solution. Weird in 2020.1 everything worked for me.
