Here’s a preview of the rig for the Dad character. I considered using HIK but Maya’s HIK solution creates an excessively complicated network. Instead, I stuck with a custom rig with IK-FK switching, character sets and definitions.
With this rig, I can apply mocap and switch between IK controls, FK keys and mocap using a weighted value. At the same time, the network is not overly complicated. IK controls are held to just what I want and adding another control during the middle of production won’t mean recharacterizing or recreating keys.
