I downloaded one of Michael's hair mods and changed the color in Photoshop. I then went to OpenIV and extracted "hair_diff_000_a_uni" and changed the name to "hair_diff_000_b_uni" and c and d and so on. I replaced the original textures of those files to the images that i've photoshoped but those files wont show up ingame using the trainer. Only the "hair_diff_000_a_uni" shows up ingame. But using OpenIV's model viewer I can see the hair with my new textures. Can someone help me know what I did wrong so I can get them to show up in game?

English is not my native language so I hope you understand what I mean.
