Recently, I saved a hand pose for Mike 3 from the right hand and tried applying it to the left side and it barely did anything! When I used Figure > Symmetry > Right Arm to Left Arm, the hand changed properly. So this explains why, eh? Strange. Are we sure it only affects right hand pose to left hand pose and not left hand pose to right hand pose? I never noticed a problem with hand poses that shipped with Poser. I wonder how they did their hand poses? (Also, does anybody else think that the second joint of Mike 3's thumb is unusually long? :) )
