Hello, I have a USDC file with vertex color (WITHOUT textures), and it displays perfectly in Preview. If I package it in a zip (without compression) and rename the resulting file to USDZ, I can see it without any issues in AVP and Mac. However, if I send it to an iPhone, the vertex color does not display.
Is there anything else I need to do besides packaging the USDC without compression in a ZIP?
Thank you very much.
