Here, we dive a little deeper into how I like to create my 3 by 3 master controllers in toonboom harmony. We look at the head in this video but the same principles can be applied to any other part of a rig (the pupils, torso, etc.) All you need is 9 good poses to feed into the grid wizard.
The first part of the video focuses on setting up your rig and then the 2nd part focuses on actually creating the controller (in realtime, so you can see exactly what I do).
