I've actually been learning how to do this type of stuff. I have the models, the stages, and hope to have a better grasp of MikuMikuDance one day. I've already managed to get the Director of SOLDIER, Lazard to dance/jump around:
The whole process is somewhat difficult, as the editor for the models which is a VERY IMPORTANT step, does not have a deselect option when assigning bones to vertices, so I'm often forced to undo a ton of selections to correct ONE that I missed/selected on the wrong part.
