The P5 figures do not have head shape morphs in their CR2 files. They are accessed in the Face Room and come from a single file that is binary and unless or until some new tool is developed is a fixed component. The Face Room is about textures and morphs. Additional shape morphs can be added to the CR2 of course. I am not sure how they will interact with the Face Room magic. As for 36 materials calls: If you open the OBJ file and look at the f section, you will see that the usemtl lines within a group are shuffled like a deck of cards. I have seen figure where a material only has one line before it switches to another. There may not be 36 separate materials, but there are 36 usemtl lines in the obj file - a lot of them are duplicates.
