Great post, I have morphed V3's toes in Max where I work on the left foot and mirror it to the right one.  I tried it with V4 and when I import it back into Poser, the right toes explode.  I have tried everything I can think of and no dice.  I just import the whole figure back into and the morphs are good on both sides, but the right foot's texture and bump maps get messed up.

I have morphed the feet a bit because its the one thing that just doesnt look realistic.  I know we can put them in shoes, but sometimes you can't and its a shame when everything looks realistic except the feet!
