Ive never had that issue after compressing (in base geom or via morph) But at any rate, UV Switching on its own will not solve mesh defects. That's common sense. The intention is to use it with a series of other techniques, such as when using morphs that would otherwise deform the texture, or smoothing of the geometry to correct defects and such.

Yeah, there's definitely a good amount of stuff you have to cover when doing development. But then, everything thats worth something, never comes easy or quick.
