I get a new errror when trying to convert an gltf to usd.

Any idea where it could come from?

converted usd file extension from .usdz to .usdc: /var/app/current/tmp/9292b98543fcb47a2818f62cd71f62e03818eda225d96f818cb98c2cbfa9b98d/usdz/dist.usdc

While trying to re produce the bug, I just realised the reason. The USDZ was created correctly (that explains why on mac it’s previewable) but the maps were too heavy (4096x4096 maps for the ORM for 1.6 MB).

We are now converting all our maps to 2048 x 2048 jpegs.
