If I am going to uv texture something with different parts to it, such as in a land I might want mountains, dirt, and grass. I would need a pretty big resolution. is it ok to use super high rez images? Also, if I have a sword that is all one object, but requires different parts to it, like the blade, the handle, and that weird thing between the handle and blade. as well as teh bottom of the handle, and I want to texture it. Preferably with some reflection just on the blade. How do I do that?
Here is the tutorial I am working with.
