How to prepare usdz file with occlusion material

Hi everybody. Reality Kit allows us to prepare a simple sphere, plane or cube "made from" occlusion material to hide some AR content.

It is OK, but I need some more sophisticated shape than a simple cube or sphere as an occlusion mask. It needs to be a USDZ asset, that I use in Reality Kit. I need to apply the occlusion material to this usdz asset.

Does anybody know, how to do it?
