This cool eye rig is powered by Geometry Nodes.
Blender Artist Max Edge, known for the amazing FX made in Blender, has shared a cool eye rig that Character Artists will definitely find useful. Unlike many other Blender-made eyeballs, Max's setup allows you to change the eye's color, alter the depth and size of the pupil, iris, and cornea, and even grants you the ability to create narrow, cat-like pupils. The rig utilizes Geometry Nodes and works with Blender 3.1. You can also check out the video attached above to learn more about the production process behind the setup.
