So since I don't know how to make those eye rigs involving eyeballs, I'm taking an approach on 2D eye-shaped meshes (eyes and pupil. My question regards around moving the pupil mesh along an angled axis on a rig.
This is the initial idea of how I want the rig to move the pupil
Is it possible to rig the pupils to move along the x, y, and z corners within the eye location? If so, how can I make it work?
