DAZ uses a program that I have only seen reference to the one time. The name did not stick with me. The ones in common use are Flesh and Texture Weapons - both are way more than I would pay for what they do. UVM Pro will let you select and map individual facets, but the mode you use - detaches them - so it is not like pealing an orange. It is difficult not to get artifacts - facet to facet doing it this way and slicking them back together after you get them flat. It all depends on how compulsive you are. My choice is to try and protect the original unfolded mapping at all costs - since I cannot really duplicate it.
