Are there guidelines or best practices for exporting a RealityKit scene to a USDZ? Is this possible? I’ve seen just a little about the ModelIO framework. Is this the tool we should be using?
I don’t think we have any guidelines about this, since exporting/saving a scene is not supported by the current APIs. ModelIO seems like a reasonable solution to me, but you might also want to file a feature request for this on Feedback Assistant.
