So I'm having a similar issue, however, once I have created and exported my models as a .gltf and imported them into Reality Converter, they are converted correctly and exported correctly into .usdz files Buuuuut! Once i create a scene in Reality Composer (Everything looks right in Reality Composer) and try to export as a .usdz file, the textures completely break, albedo, roughness and metallic... Anyone care to share their wisdom?

Hi, thanks for getting back to me I have added a screenshot from Reality Composer and the previous image is what it looks like after USDZ export from Reality Composer. Yes, the model does look and play right when exported as a .reality file Is there any way of using a .reality file so that you dont need to have reality composer to view it? Such as viewing it from a QR code? That's kinda the end goal of this project

Sure thing, filed on Feedback Assistant - FB9801210 Thank you for your help and time

No feed back at all... Actually quite astonishing how I have heard completely nothing since posting this issue. The issue is still there, countless reworks and redos result in the exact same issue No help at all from Apple Developer Support
