Meghdad Asadi Shows an Easy Method for Finding the Right Place for Pole Vector Controls That Won’t Move You Limbs

Ever set up a pole vector constraint to a knee or an elbow of a character and have the joint pop out of place? We all have. Ther is a way to find the proper place for that controller before you set up the connections, it might involve some math though.

Technical Director/Animator Meghdad Asadi has another way, one that is easier to see the underlying process of what is happening. “I came up with the idea a few years ago and used it since then for a character I’m rigging,” Meghdad says. “It’s way easier to understand and see the process, especially for those who don’t know math.”

Meghdad walks through the technique in a short 12-minute video. It’s perfect for putting the Aim Controller for the Leg IK or Hand IK setups, using the plane created by any given three joints in 3D space.
