Shaders do not compile in Unity 2022.3.5f1 #771

I'm using UnityGLTF 2.13.0 and when I try to compile PBRGraph it ends with errors:

UnityGLTF/PBRGraph has too many Shader variants (2359296). To resolve this, go to Project Settings > Graphics and remove this Shader from the Always Included Shaders list. For more explicit control over how Unity includes specific Shader variants in a build, use a ShaderVariantCollection.

And a warning:

Shader warning in 'UnityGLTF/PBRGraph': pow(f, e) will not work for negative f, use abs(f) or conditionally handle negative values if you expect them at Editors/2022.3.5f1/Editor/Data/CGIncludes/UnityCG.cginc(513) (on d3d11)

Thanks. Unity seems to have changed how shader variants work (again!) in 2022.3 and we'll need to look at how we can work around that.

Hey, these issues should now be fixed. We also added predefined ShaderVariantCollections to make it easy to use UnityGLTF at runtime, can you please try it with them?

One for Built-In RP and one for URP/HDRP: image
