Is it possible to add child of constraint to IK handles?

Yokenstein 3 years ago • updated 3 years ago • 2
The object (sword) needs to be grabbed onto by 2 hands. I have the game object parented onto one of the hands (not via Umotions parenting system), but I want the other IK handle/hand to stick to the game object, rather than me trying to manually keyframe animate the correct positions of the hand. Is this possible?

Hi Shayan,

thank you very much for your support request.

Yes this is possible. If you have setup your IK chains with the IK setup wizard, a child-of constraint was automatically added to each IK handle but it's in IK pinning mode. Disable the IK pinning mode in the child-of constraint setup (in config mode). This replaces the IK pinning toggle button with the regular "parent" field that allows you to select any arbitrary parent.

If you've setup your IK chains manually, you can just add a child-of constraint to your IK handles manually (in config mode).

More information about the child-of constraint and IK pinning can be found in the following two video tutorials:

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

Best regards,
Peter
