you won't be able to publish app made with xcode beta on the app store anyway. Just went through the process - and got this info when I was trying to submit the app for Review via App Store Connect.

I'd love to know more about this too!

Hey I'm running into the same issue - PBRSurface displays just fine, when I'm using: occluderMaterial = try await ShaderGraphMaterial.init( named: "/Root/Object/Occluder", from: "Immersive", in: realityKitContentBundle ) But when I connect OcclusionSurface as CustomSurface it breaks and I get error: Failed to load a shader material: materialNameNotFound printed in the console. I've been testing this on Apple Vision Pro. Why is it happening am I setting something wrong in the Shader Graph, or is that a bug?
