Okay, i've downloaded Cox's UV mapper, followed his directions, played with it a bit, AND I STILL DON"T GET IT! I may not be the sharpest tool, but I get the feeling I'm missing something somewhere. The Ray Dream user's Guide is none too helpful. The only real mention of UV mapping that I found talks about how boolean perations will change UV coordinates; there is brief discussion of mappping modes (parametric/box/cylinder). But nothing more detailed. It's kind of like those how-to-draw books my son has; the first three steps shows five connected ovals, the last step shows a fully detailed F-16.
