Using OcclusionMaterial on macOS and iOS works fine in Non-AR mode when I set the background to just a simple color (https://developer.apple.com/documentation/realitykit/arview/environment-swift.struct/color) but when I set a custom skybox (https://developer.apple.com/documentation/realitykit/arview/environment-swift.struct/background-swift.struct/skybox(_:)) the OcclusionMaterial renders as fully black. I would expect it to properly occlude the content and show through the skybox behind it.
This happens with box ARView and RealityView. On current iOS/macOS Betas as well as on older systems, e.g iOS 17 and macOS Sonoma.
