Two bone IK is jittering when attempting to set the location to a socket on the weapon skeleton.

Hi everyone,

I’m trying to attach the left hand of my character to a weapon using two-bone IK, but I’m encountering significant jittering when the IK is applied. For the setup, I’m using “Get Socket Transform” to retrieve the weapon socket and then using “Transform to Bone Space” to calculate the final transform for the IK. It’s seems that the left hand it snapping between before and after IK.

Has anyone experienced this issue or have suggestions on how to resolve the jittering?

I’ve uploaded two videos to demonstrate what’s happening. One video is slowed down for better clarity.

Thanks.

Could be the usual one frame lag sort of issue.
