Hello all, I'm having an extremely hard time getting my transparency to show up in .gltf and usdz. When I upload my obj files to Sketchfab, the opacity shows perfectly. When I take these same files and convert to USDZ or .gltf per the client's request, the opacity of the material does not show up. I've seen the tutorials through the years but non of these help. Attached are my output settings, the way it looks as a USDZ on my ipad 2018, and how it looks in 3Dcoat Please help.
