...but broken again in iOS 18.4 beta 3 (22E5222f) !?

Thanks, but the skybox doesn't show up if the camera is set to world tracking. Still occurs with iOS 18.2.1, Xcode 16.2, and I received no feedback regarding FB14821481 😢

...and still occurs with iOS and iPadOS 18.1 beta 6, Xcode 16.1 beta 3...

Still occurs with iOS and iPadOS 18.0 beta 8, Xcode 16 beta 6...

...and still occurs with iOS and iPadOS 18.0 beta 8...

Sure, here you go (sorry for the late reply): https://www.dropbox.com/scl/fi/zgyh9mwlabhbi1q0pw5ml/SwiftDataCrash.zip?rlkey=wglyagwq2wbs3lwml7dye3etg&dl=0

Perfect, opening the usdz files (which I downloaded from NASA) in Blender 4.2 and re-exporting them as usdz apparently adds the subdivisionScheme property, and the models look correctly now. Thanks again! P.S.: It would be great if the Vision Pro Simulator would exhibit the same behavior as the device in this regard. I wouldn't have discovered this issue with the Simulator alone.

Thanks for your reply Michael, that explains it. Ok, I'll try to add this property to my USDZ files (in 2 weeks, I'm currently on holiday) and will report back...

Oh I see, that solves it for me, thanks a million!
