Takes a Wavefront OBJ with textures and attempts to squash them into a single texture file.
I put this together for the purpose of packing complex models with multiple textures (such as ripped game models) into a single .obj and texture file for use as custom models in Tabletop Simulator. Initially, I had to do this by hand -- first, combining the textures in GIMP and then going through in Blender moving and scaling UV's to fit. This process felt awfully repetitive, as well as awfully automatable, cue this script.
Written in Python 3, and using the great Pillow image processing/manipulation library.
