The textures are extracted from Zbrush. I can't make new textures. If I merge the parts in Zbrush I lose the lower sub divisions which makes it useless for a game, or I lose the higher sub divs and can't make proper textures, normals etc
You've got alot to learn! Look into a software called Xnormal, you can transfer polypainted textures from high poly Zbrush objects onto your low poly meshes.
I know. And what you saw I managed by watching videos in youtube... Anyway. I managed to drop the parts to three. I believe it will be ok now.
I didn't actually have a look at it due to the huge ammount of models, that's just crazy, if you're making a character, you really should bring it into the editor as one mesh.
It worked. I found out what went wrong. It was a problem with the paths I selected to import the materials. Everything looks fine now! Thanks a lot for your help! I would have smashed my screen if you weren't around.
