Issue with Inverse Kinematics Implementation

Hello ,

Thank you for reaching out and providing detailed information about the issue you're experiencing with the Inverse Kinematics (IK) implementation.

The behavior you described, where the entire body rotates when turning the head, could be related to how the IK system is configured. Here are a few suggestions to help resolve this:

Check the IK Constraints: Ensure that the constraints for the body and head are set up correctly. 

The head rotation should not influence the entire body unless explicitly configured to do so.

Review the Rig Setup: Verify that the rig hierarchy and IK solvers are properly assigned. Misconfigured rigs can lead to unintended behaviors.

Adjust Weighting: Look into the IK weight settings for the head and body. Reducing the influence of head movement on the body might help achieve the desired behavior.

Compare with Meta Sample Scene: Since you've observed the same issue in the Meta Sample Scene, it might be worth checking if there are any updates or patches available for the sample. Additionally, reviewing the sample's configuration could provide insights into potential fixes.

We hope you find these information useful. 

Best regards.
