Can you specify what kind of data you're talking about? If you mean by data captured in checkpointDirectory in ObjectCaptureSession, I don't think you can create them from AVFoundation or ARKit, since those folders are automatically created with formats that are not specified publicly.

I've ran into this issue as well, while using the .usdz formatted file instead of .reality. It's just my speculation, but maybe QuickLook's AR & Object toggle is only available on models that are .reality format?

Hi, did you import RealityKit in the same scope?
