Model never loads in AR on iOS QuickLook.

Description

QuickLook keeps loading forever for glb models.

Works fine on Android. I tried to convert it manually to usdz and then it works.

Update: Interestingly, I tried another glb file and that works. But the model I am using is not working.

My model is a scanned object from a 3d scanning app from iOS. I compressed the file (https://github.khronos.org/glTF-Compressor-Release/) with ktx2 texture. But still that does not help.

The forever load sounds like a QuickLook bug (@grorg), but in general we don't do a perfect conversion of all GLBs to USDZ, it's only best effort. If it fails, please use Apple's converters and specify your own USDZ as the ios-src.

Thanks for the reply. Can you provide me some directions on the conversion? I honestly don’t have much clue where to start. I am using Unity and I found a few editor solution, but didn’t find any runtime converters. It seems like I have to write my own.

Best bet is find an Apple machine and use their free Reality Converter software.

I tried it on other converter and it works fine. Seems like the usdz converter that comes with modelviewer may have some issue.
