Im not a complete expert in C4, I can use it with some degree of confidnce but I have not gotten into UV mapping yet. I pretty much use the spline modeler for all my models, I get a headache with the vertex mode. I'll check into the UV mapping when I get a chance. I started with Ray Dream and worked up from there to C4, I kind of like the seperate modeling room, its easier to work on a section off in it's own private little cubbyhole.
