"Then I might use the smoothing tool at the edges.  It's a little more work, but I am very glad I forced myself to make it useful."

Yeah, it's possible to carefully do FBM's because the MorphBrush only moves the parent's vertices and not the child's across a seam, but that's not what I meant.

I can take an unwelded Poser mesh, weld it, fully smooth/morph it with the morphbrush across seams, and then "un-weld" it again so that the original morphs will still work.
Took me only a year to find that exact workflow, but I can now morph and smooth already morphed or even scaled figures in P7 or ZB3 without problem.

No need to use the welded objects from the geometry folder or to carefully work along seams any more.
