Problem with downloaded usdz file

Hi, I have a problem because the 3D file I uploaded on sketchfab it works fine but when I download the generated usdz, it doesn’t work on external software. The model is with bones animation.

the problem is quite urgent. Thanks.

Which software have you tried it in so far?

Blender and also an ar service from a client. It works as gltf and android but not with usdz and apple devices

I can confirm the usdz does not open as expected in Blender 3.0, I’ll report it to our 3D team.

It looks like we were already discussing this model over email. I’ll continue the conversation there.
