Please advise per topic. 7.1.2…

Shadergraph stuff is really a pigs ear in XR/VR, honestly. It’s not the first problem I’ve had, it’s the 3rd unique showstopper

Getting thin having to work around constantly and having not much if any support.

Shader error in ‘Simian/Prototype’: undeclared identifier ‘unity_StereoEyeIndex’ at /Work/VR/Library/PackageCache/com.unity.render-pipelines.core@7.1.2/ShaderLibrary/UnityInstancing.hlsl(161) (on d3d11)

… Yet the precompiled URP shaders such as Lit work fine? Why is this happening?
