I am trying to use it to find out why PBR textures aren't rendering, the presentation in Converter is much clearer than Composer. And I am confused as well : if the only point of Converter is to convert other formats into USDZ, why does it have USDZ import ?

Just submitted the bug report, the ID is: FB15524321

If you advise not using Multipeer, what is available in its place that supplies the same functionality? I see another response that says "Network framework", but I don't see a replacement for sendResource there, or any of the other nice high level functions Multipeer provides. Do you have any suggestion?
