I'm rigging just a hand (like Thing from Adams family) so sorta like a spider. I have IK bone chain for each finger, but i want to apply a spread on the metacarpal bones on the hand(similar to a FK hand set up), that spreads each finger's IK chain.
I'm stuck on how to update the IK goal target. As I have the IK goal a child of the master transform and the IK root a child of the cog(center of gravity)transform. I would ideally want to rotate the IK finger chain around the IK root transform's Y space.
Any suggestions greatly appreciated
