I can successfully create custom morphs for every body part of Michael 2 except the genitals. Whenever I apply any modified .obj to the genitals i get the result pictured above. I use 3d studio max 4.2 to create my morphs. I assume the problem has something to do with how the genitals can be switched on and off within poser. If anyone knows the solution to this you will become my new God/Goddess!! (the headache is about to do me in :)

It looks like the vertex order has been reversed in the morph. Try exporting from and re-importing to Max prior to morphing, even though it apparently didn't reverse the order in your other morphs.

I have had no problems in morphing the gents on Mike. Ron
