@Dr-Sassi Hi,

Thanks so much for getting back to me on this, I really appreciate it. I've tried to follow your instructions, though I'm fairly certain I've followed them incorrectly as I don’t understand the rational or function behind each step of the process, particularly the role of the pole vector and where each of the nulls should be positioned in the joint hierarchy if the hand is the bone I am trying to impact.

I’ve tried watching some of your tutorials on IK tags but to no avail. I can’t attach the file itself as it’s too large but I’ve attached an image of the setup.

Hi,

I’ve tried following this tutorial:

to “lock” a hand to the surface of a table but no matter where I position the “constraint null” in the joint hierarchy of the reference mocap the rest of the limbs keep warping away from the “constrained” hand. Is there a really obvious way to solve this that I’m overlooking?

Thank you for any advice you can offer.
