I am loving the Xcode Reality Composer --> iOS workflow, and have had good luck with usdzconvert.
Today I tried a Mixamo character with animation. After configuring python with the Autodesk FBX SDK, i got a good conversion (I thought). It passed.
Animation, fine. But the model had the diffuse texture repeated in tiny tiles.
Odd thing - it opens fine in Xcode, but does not appear correctly in either the MacOS Reality Composer or the iOS version.

Any ideas? Thanks!
