A bunch of joints, animated, cannot be converted

See original GitHub issue

I basically have bunch of joints, animated, under Armature, exported from Blender.

I don’t have root of this bones, wondering if this is an issue?

@enzyme69 interesting, I was able to get all the toruses to animate on iOS, though it doe look different in XCode Beta 6. This could be another difference in behavior between Mac OS and iOS. I made a screen recording on my phone for reference. IMG_1338.TRIM.MOV.zip

@kcoley You are right!! It’s also working and animating on my side on iPhone and iPad.

I guess we can send bug report to Apple. MacOS and iOS USDZ has different behaviour. Sometimes it works on MacOS and not on iOS… at least this works on iOS!!

Thanks!
