I was making a model of the classic Iron Man armor from way back and ended up retopologizing the helmet, but now that I've been trying to piece together a new UV mapping layout, I realize I need to do the whole body. It has that same mushy quality I don't want it to have. I realize now that certain parts of the human male model I made, although adequately realistic, have terrible geometry and desperately need to be remade. The easiest way is to retopologize.
Good UV maps depend on smooth topology. If you don't have that, mapping is a nightmare.
