Hi @JasonRTBond, it seems like the cube ist still captured in a window. Go to VolumeToyApp and make the window volumetric, i.e. WindowGroup{ ContentView() } .windowStyle(.volumetric) If you just want to change the size of the window: .defaultSize(width: 1200, height: 1000) -> insert your dimensions Hope that helps. Let me know if you need any more help!

Please share your code with us. I am sure we can provide some guidance. My best guess is that you need to change you Scene Manifest as your app might start with a window or volume. Please try: In your Info.plist set "Application Scene Manifest" > "Preferred Default Scene Session Role" to "Immersive Space Application Session Role". Let me know if this was helpful!

Thanks for sharing. This information was very helpful!
