Anonymous 1 month ago updated by Peter - Soxware Developer 1 month ago 4

Hi,

Is there any way to pin the elbow or knee instead of the and or foot?

Hi Scott,

thank you very much for your support request.

Yes, you would need to setup an IK chain that only includes the upper arm/leg. The IK handle would then define the elbow/knee position (instead of the wrist/ankle position). As the IK setup is UMotion project wide, I recommend that you do this in a separate UMotion project (in order to not destroy the regular IK setup probably used by other animations in your UMotion project).

For more information on how to setup IK chains manually, please follow the second part of the IK video tutotrial:

Here's how to setup IK pinning:

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

Best regards,
Peter

I have setup both upper arm and leg for use IK Pinning.

They work, but IK Pinning menu has been gone. However I cannot adjust frame range using the blow bar:

IK Pinned menu is still invisible, but i can adjust frame range after restarting umotion.

You need to add a child-of constraint to your IK handles (and enable the child-of constraint's IK pinning mode):
