@SaintFox,

Quote - I get is a big crease below the abdomen...

Could you post a picture of the problem, preferably with an arrow pointing to the exact problem area. I don't want to go tilting at windmills again.

In the mean time, the above image is what I am seeing after applying your morph. I suspect It's not what you are seeing. I even suspect there may be a Poser bug involved here, but I want to be sure I am attacking the right problem this time.
