To clarify what I see happening with a subd morph when a body part is set to "subdivide separately from figure." The image on the left shows unmorphed Antonia at subd 2, the one on the right a test morph I made in Blender and loaded into Poser with my script, the middle one what happens to the test morph when I subdivide the eye separately. If you look closely, you see the smoothed out remnants of the lower one of the two ridges I made, which happened to align with the subd mesh and thus get baked down. The upper ridge on the other hand is completely gone.

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