Issues & Bug Reporting (Fab)

Summary

Been having a hard time trying to find out if I’m doing something wrong, but does the FAB 3d viewer not support PNG alpha for transparency? When I try to use the color PNG as the file for transparency, it makes the whole piece of geometry transparent as if it were glass. If I try to use cutout, it just makes the whole piece of geometry invisible. Do I have to have a dedicated file for transparency? On Sketchfab, this worked just fine and it gave several helpful options. Models that I migrated over seem to be OK, but new models will not work correctly using the PNG. Is FAB just buggy and this will get fixed or is there some setting somewhere that I haven’t set?

What type of bug are you experiencing?
