Does anybody know how Jeremy Ernst got a reverse roll sorta rig on the hand of this character he’s showing off? http://jeremyernst.com/artwork/306815_Rigging_Demo.html
My assumption is he’s got duplicate joints of the beginning of each finger with IK on it. Those IK stick to the hand control. Then the rotations are either parented before the actual joint so it can still be rotated, or are added together into the final finger rotation. And then he probably has two IK on the thumb.
Then that rides a reverse palm rig that can rotate the wrist ik up, and there’s probably IK for the hand to keep it planted.
Which if is the case, then it probably wouldn’t work if you had joints in the palm of the hand for each finger for hand cupping and a bit of spread. I’m assuming it only works because the joint chain goes from the hand straight to the first knuckle. (So I’m guessing he has 3 joints per a finger, rather than 4, starting in the wrist)
Can anybody think of a way to get both? That reverse rig bending, fingers that can plant, but still have control over the rotation at the wrist for each finger, but the ik starts at the first knuckle, and rides that reverse rig? I can only figure out how to do it without the joint in the wrist for the extra rotation.
I’m sure that description is a mess, so let me know if you need more explanation or an example file.
