USDZ Export with Materials - Rhino 8

Hello All,
I am experimenting with the .usdz exporter in Rhino 8. Is there a way to export the usdz file with materials? I have tried exporting the polysurface geometry as usdz, as well as converting the geometry to a mesh with the “pack textures” before exporting. Both times the result as viewed from ios Quick Look on iPad is a pink striped pattern. Is there any way to fix this?

The materials should be in the usdz file.
The problem is likely with the viewer.

To confirm, if you export as usda you should see the material files on you disk next the the exported file.

Could you provide the 3dm file?
