The Eye Rig is based off a simple premise, a 6 joint system (3 top and 3 bottom) with pivots at the eye centre. The rig features two methods of rotating from the pivots which are additively added together.
1. Lid Slide
The eyes can follow an aim control or rotate locally to the head or in world.
Drag and drop the rig into your scene, setup the pivots and hide the placer control. Adjust the settings and skin as desired. This rig also comes ready for correctives which are the additive result of the follows and blinks combined.
