Example files
I have provided 2 gltf files, which are at some point converted to .glb and then to .usdz using usd_from_gltf. I Also provided the converted glbs. It's worth noting that the gltfs are draco compressed.
The files are identical except that TEXCOORD_0 and TEXCOORD_1 values have been removed from the attributes under primitives and also from attributes under extensions.KHR_draco_mesh_compression in one of the files.
To reproduce, simply convert the file that keeps TEXCOORD values (broken.glb) to usdz.
The glTF Validator claims that both the non-working and working files are valid and glTF viewer display the models without any issue.

Any ideas why this might happen?
