like:
let mat = try await ShaderGraphMaterial(named: "matname", from: "reality")
currently I use an USD file with materials like so and it works:
try await ShaderGraphMaterial(named: "/Root/matname", from: "file.usda", in: appBundle)
when i try it with .reality i get "NameNotFound". so is it possible or do i have to have a bunch of dummy entities with my materials assigned so i can find the entity>components>material?
or what's the best way to author materials in RCP3 for quick access in realitykit?
