rotate a joint in opposite axis
Basically, I have created my skeleton for my figure and for the left arm I created a locator with some set driven keys to control certain hand movements, but rather than have to go and set the same hand movements up for the other arm I duplicated the arm (with upstream graph checked) and then scaled it to the other side of the body. This part all worked fine but when I went to rotate the new arm, it rotated in the opposite direction to the way I moved it.
So this is why I am after some kind of expression that I could attach to the joints to make then rotate correctly. So I need an expression that will tell the joint to rotate in the opposite way.
ant help or advise would be greatly appreciated
