Well... since the UV seam splits don't seem to submit readily to an algorithmic solution, I've decided the way to work around this is to build a UV editor.  I can't seem to find one which will allow the user to split the texvertices by hand, which is necessary for the corrections we need.  So I've started this new sub-script for TDMT.  The attached is the rudiments of a UV editor which will work within Poser.  Right now it's just a novelty, as it doesn't save yet, but it seems to show, so far, that the idea is feasible.

I hope to make this able to load an actor for editing and another for comparison, in the background.  Then the background actor could be used as the frame of reference for moving the texvert positions.  This could also hypothetically be used to create a new .vwt comparison from the UVs, which is an interesting idea to me.

Right now all it does is allow you to select and move vertices, as well as weld and split and find back-facing polygons (which is slow, because I'm not yet using the .pyd for this).  Hold down shift to select multiple vertices.  Hold down control and drag to use a selection box.  Oh, and the current actor has its UVs displayed.  I need to add a better selection process....
