I've thoroughly read through the documentation regarding transparency. I have sets of objects, plastics, and decals/stickers, the decals are on a 2face/1poly plane which are then sized and positioned with the plastics. I have this working in 3dsmax with opacity maps just fine. When I apply the mask/opacity map in sketchfab it isn't cutting anything out, I tried playing with the threshold and inverting but not the result I'm looking for. This should be fairly straight forward so I'm not sure what the issue is.
Any help would be appreciated thanks.
