You asked about selecting - In the options available for your setup of UVM, there are two choices for select - facet is the one to use. When you get a map of an object, any place on it - hold the left button down and drag your cursor diagonally. A box will form. Any facets in it will turn red. These are the selected. These you can name or hide or rename or change shape or assign to groups as well as materials. UVM will let you recut a model. UVM also has regions. As far as Poser, Carrara, RDS regions ain't in it. They can assist in mapping and layout, but I have never utilized them. You can light up any facet if you get just one point (I think) The only hassle is that you cannot add to an active selection. You left click outside the box and everything is unselected. If I want to add to it, I either put the facets in a separate pile, or assign a new material name to them so that I can isolate or select at will. Once you have a box, you get the usual eight control points to resize, plus when in the box, the cursor is the quad direction symbol and you can drag the selected facets anywhere. Sometimes, if I am cleaning something up, I drag facet over into a big pile. You can remap at any time - even a single facet. If you select the pile and do a remap using the same aspect that they came from, they will go back.
