That's interesting Jaager- I carefully name all my groups from the bottom up in RDS, and they are always all there when the model gets to UVM. Then for grouping within UVM, I use the "region" method. Also as you mentioned, you can pull a model apart poly by poly in UVM and then assign them to various regions- it works like having several folders open that you can drop all the pieces into as you isolate them- once you have isolated all the polys you want to be a part of a region, then just select by region and make a new map for just that region, which will pull all those pieces back together perfectly. Also in RDS you can select individual polys that are still attached to a larger mesh, and "Name Polygons" under the Select menu. When loaded into UVM, those named polys show up as a totally separate group. This means you can have larger pieces to your model, such as the car above, and not have to break it up just for later mapping of materials. The "Name Polygons" feature does not interfere with naming the whole mesh, as that interprets in UVM as the "root" group for any one mesh in the whole model. Also, you can rotate the whole model in UVM, but as long as you do not remap the whole object, you can map only certain regions at that orientation, whichever angle happens to work best for that particualr region. For instance, the car model above could be rotated 45 degrees or so to align the windshield more straight on with one plane. If you have previously separated the windshield using UVM's selection tool and assigned to a region, just select that region (with the model rotated) and generate a map of the windshield. Tada! A flat windshield map. BTW, "rotating" the model in UVM is reference only- that is, it does not "really" rotate the mesh or the particular region- it is just a tool for orienting the model to get a better, straight on picture of any part.
