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.

Blender File

This is the initial location of the pupil. enter image description here

This is the result of a basic move only along the x axis.(Usually the result when attempting to move the pupils on a rig.) enter image description here

This is the initial idea of how I want the rig to move the pupil

enter image description here

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?

  • $\begingroup$ So it kinda works, but it only orients on one eye. When I try to do the other one, it moves on the orientation on the first eye, even when selecting on the opposite face. And other times it just doesn't orient on the faces. $\endgroup$ May 4 at 21:27
  • $\begingroup$ you will have to create another transform orientation for the other eye @WannabeHere $\endgroup$ May 4 at 21:28
  • $\begingroup$ Ok that seems to do the trick. But if I wanted the eyes to look up and down, would I have to apply the same principle? $\endgroup$ May 4 at 21:35
