Hi,the split_obj.py is very useful but i found it will lose material information in each obj file split, it will be well if generate a new mtl file for each obj file.
or give an option could named each obj file by material name.
Sounds like a good idea. It would be useful to have original OBJ materials somehow preserved in CTM pipeline. So far I was just doing this manually.
I'll try to figure out something, maybe output materials into JSON snippet.
Or we would update split_obj.py, but I haven't studied python.
