Come on Apple. Your developer forums are less than helpful. It would be great if Apple could spare an expert staff member to answer some questions, such as this one on line to help the rest of us.

Hi, you can download the Diorama sample project here. [https://developer.apple.com/documentation/visionos/diorama] Thanks!
