/3/ - 3DCG

Hello.

I'm wondering what's the best way of having an IK setup that allows me not only to move the arm independently to the body (which I already have), but that also allows me to "pin" the IK target to certain body parts, for when I want to have the character hold their hand on their head or chest, for instance.

The only way I'm sort of found of doing this is by using copy location and rotation constraints to create a kind of "virtual parenting" to the bone I want to stick with, but it feels really unnatural to just be playing with constraints like that during actual posing, so I was wondering what method people use to do this.

Pic related. I have an arm IK setup, and I want to tie the IK target to the breast, so the hand will follow whenever I move the ribcage.
