This is for Milkshape users (not for beginners)
When your legs move like this in Milkshape:
You might want to manually change the bone assignment. This happens a lot after using the MeshToolKit. Somehow a part of the right leg is attached to the left leg. And vice versa.
All you have to do is... back-up first! (serious, save your project, use autosave, whatever)
Then select the vertices that cause this problem and open the Extended Manual Edit (under Vertex)
(Not all in once, just a couple and after some more)
You see the left leg, but for the mesh it's their right, and they don't want their right leg attached to their left, so make it zero (0). It's math: Bones are 100%, pelvis wants 3%, left leg is zero, so right leg will have 97%.
I move the numbers of pelvis to column of the right leg, because otherwise in bodyshop I get moving vertices. Something like this, don't know why??
It will look like this after.
I hope this will help some of you. And serious... save your project first before changing bones.
