A look at using the FFD (Free-Form Deformation) Deformer in Cinema 4D for rigging and placing cartoon style eyes on a character from Ben Benton, creating individual controls for each eye, as well as being able to have control over both eyes at the same time.

This is something I wish I’d known when I was working on my last full character piece and I’ve finally put two and two together and worked it out. So I hope you can get some use out of it

The overview is that you want to have they eyes in a shape other than a sphere for a cartoon look, however, it will be difficult to have the eyes rotate if they are not perfectly round; If not perfectly round, the eyes will not always fit inside their intended sockets. Some have circumvented this by animating the texture of the pupil, thereby making it look like the eye is rotating, however, I feel that is an unnecessarily complex solution where deformers can simplify the rig and create a great result.
