I'm trying to upload several obj files and a sketchfab.timeframe file to do some stop motion animation. I've noticed that if I upload a single file without the sketchfab.timeframe the textures upload fine. However if I try to upload multiple files (or just this single file with a sketchfab.timeframe for this single file), textures do not appear.
In one instance the textures did not even load and I had to load them manually. Currently, it appears the textures are attached, but they render as single colors only (sort of the "base" color of the texture).
Any help is most appreciated!
