As the controllers are going to be the interface between the animator and the character, they have to be intuitive and easy to manipulate. That’s why Duik Bassel not only introduces new shapes to make them easier to recognize, but there is also visual feedback on the controllers to see what the controllers are doing! And of course, they can be easily personalized, you can change their colors and shapes as you wish.
This is the Controllers panel in Normal mode.
The controller panel consists of the list of controllers shapes you can use in your rigs (or which are created with the tools like the Auto-rig), and some useful tools related to controllers.
There are 3 special shapes: the slider, the 2D slider and the angle controllers. They are not meant to be used like other controllers - with parenting or IKs, etc. - but with the “Connector” or expressions: it is easy to get and connect their value to any other property and control almost anything you want with them, in a very visual and easy way.
Controllers are standard shape layers. You can draw anything you want in the content of a controller, therefore using custom shapes is possible.
