Hey guys,
I've got a question about normal mapping. You see, I've got the new, complete Panzer IV model from my modeler today, and I'm currently skinning it up and preparing to do the normal mapping and materials to make a custom shader for it. However, I've divided the model into 5 groups: Hull, Tracks, Wheels, Turret, Gun, and Details. Each has it's own hi-res skin, and it's starting to look great. I'm going all out on this one.
But the question is, how do I do the normal mapping for each group? I've done normal mapping for models that use just one skin, but never for a model using different skins on different parts. I want each group to have it's own special NM'ing. For instance, the wheels need their own to "pop out" the bolts and rounded surfaces. The hull needs its own to give it a "scratched" and "roughed up" look, and so on. I know how to make the materials, the question is just how to I apply the correct normal mapping to the correct group and skin in the code. So each can have its unique materials and look correct.
Thanks in advance!
