heyas; mt mirror is free, so give it a shot. (on an emulator or whatever, is that what you mean?) it doesn't always work. i think you need to put the two leg pieces into one obj file (without the other pieces), and you can't have overlapping vertices (the seams, which is why you can only have one body part). and.... then i think you need to have both legs in your morph. that is, the one you morphed, and the other one you want to transfer it to. if your modeller can do mirrored stuff, it would be easier to do both legs at once in there.
