I dunno if id use it soley for create a new skin on but for some sections. Say if I wanted to redo the chestplate for Arthas and then paste it over to the model im working on. If im redrawing a chestplate on the actual unwrap, that im editing, its gonna affect my ideas, as opposed to have a blank canvas to go nuts on. So basically, I would freehand something random, then either paste it over to another skin, or keep working fom there till ive made something completely new.
BTW, Halo, dont be a dumbass, i explained already why I CnP'd the warden, and im not taking any credit for the workmanship, i just thought it would look different and fit MY needs...
Also, while putting tons of detail on an unwrap looks amazing (as we can see in worms current), it can affect the the final wrap in a way you wouldnt want it too. Its better to have something look simple and clean, than highly detailed and possibly too cluttered. All depends on what your doing.
Is there a way to extract the UV's from the MPQ files, or must you DL them from somewhere.
