Make hands follow object

Anonymous 1 week ago updated by laurenz 6 days ago 2

Hi, I was wondering if it is possible to let the hands follow another object. Let's say I have a character handling a box. I want to animate the movement of the box with both IK chains of the arms following the box. I feel like this is kind of the opposite of the tutorial video "child of" where a small box is being set as the child of a hand so it follows the hand when the hand is animated.

How would I go about making the IK handles of the hands also be children of a separate object?

Hi,
thank you very much for your support request.

"How would I go about making the IK handles of the hands also be children of a separate object?"

You need to disable the "IK Pinning" mode of your IK handle so that it is using a regular child-of constraint. (IK Pinning is just a special mode of the "Child-Of" constraint). Please watch this related video tutorial: 

Using the child-of constraint you can now make the box and the left hand IK handle a child of the e.g. right hand (or the right hand IK handle). That way both will keep their offset relative to the right hand.

Please let me know in case you have any follow-up questions.

Best regards,
Peter
