How do I put a custom skin on a custom model that I made? I just to learn how I made a square model and I want each side to be a differant color, but I don't know how to tell it that I want a certain part of the skin on a certain part of the model.
What program have you used ? Sopho, sorry about this, but... Skinning actually has absolutely nothing to do with what we here refer to as "skining".
You see, skinning is actually a part of animating a model. What we do, is that we "texture a model", so everything about skins on this site is actually misleading
aaaaaaaaaaand, as for the question. use the UVW utilities, if you are a max user.
