Oops, I just noticed: you used LaFemme at subD 2 but my script subdivided the subD 0 mesh it grabbed from Poser three times. That hints at either a mismatch between the two meshes or some edge case in the subdivision algorithm that I haven't covered. If it's something about LaFemme's mesh (and assuming the Pro version, which I don't have, doesn't use a modified mesh), I should see the same problem appear in P12.

I'll have a go at this after breakfast.

-- I'm not mad at you, just Westphalian.
