Hi there, I have a problem with USDZ Exporter. When I load my gltf in threejs everythings looks good, but when I use usdz exporter to create an usdz model, mesh normals are flipped, It doesn’t happen with all the models I use, but it happens often. Anyone knows why? Is there an option that fix this problem?

Attached one of that models.
