Is there a way to lock in the model in place and also lock its size? I thinking for AR art it would make sense to do this.
How to keep users from scaling or moving 3d models models in AR Quick Look?
W.r.t. to scaling: ARQuickLookPreviewItem has a allowsContentScaling property: https://developer.apple.com/documentation/arkit/arquicklookpreviewitem/3152993-allowscontentscaling
As far as I am aware there is no way to lock in the position (and you have no control over the initial placement anyway?)
