I'm working on a (toy) VR kayak simulator, but have limited rigging knowledge. I'm attempting to have two IK rigged arms holding onto a paddle, so they will animate with the paddle's movement, like this:
The IK works fine, the copy rotation makes the hand rotate with the empty, but moving the empty has no effect on the hand, despite the constraint. Wondering why this is, if I can fix it.. as I'm writing this, I've found this answer: Do some Bone Constraints only work with Root Bones?
...but I don't understand why I can't move this bone with a constraint, as I am clearly moving it when I pose it. I've also tried using an additional bone and a 'child of' constraint, with the exact same results, I get rotational tracking, but not location. I was also able to get a 'paddle bone' working as a child of one hand, but couldn't get it to affect the movement of the other hand...Thanks for your explanations! (how do I post the project?)
EDIT: Another method that I tried was creating two paddle bones meeting in the center, and then each separate paddle bone having a "paddle control bone" that was in the same location. I figured I could copy transforms for these control bones, and it would keep the hands a set distance apart.. but that didn't work either.
