How you doing?

So here's the thing: I'm using Source Filmmaker, I've got the Inkling all geared up for posing, I go to rotate the SubArm2 and Hand bones to simulate twisting, and the vertices of the wrist make an unnatural motion much like the twist of a wrapper. This consequently makes the render less than acceptable for me.

If there's any useful information for this problem, sharing it would be very appreciated. Stay Fresh. :)
