I want to fine tune my rig from rigfy. How do I make the fingers bend all at the same time, rotate the forearm to rotate with the hand (and things like that). Is that all in the rig property? And in the tools window I saw the " auto IK " function. I turned it on. Should I keep it on or turn it off? I don't see any difference with it on or off. My blender is 2.73. And how do I stop the mesh from going through each other. Thanks.
