I don't know if this problem is a general one. or just something that happens to me. The MAT files for changing hair colour or style (particularly Kozaburo short hair evo) though still OK in P5 just refuse to work in P6. I can change the textures manually, but this is a pain. Is there a reason or a workaround? I tried looking at the MAT files in Wordpad, but knowing nothing about the scripting language, I don't see what to change.
