Digital Human Eye Occlusion Shader

In order to create realistic eyes, CC3 Base+ characters have two new eye elements added: Eye Occlusion and Tearline. The Eye Occlusion simulates the shadows cast from the eyelids while the Tearline emulates the reflections of the tears at the line of contact between the eyeballs and the eyelids.

The topmost mesh layer for the realistic eyes is the Eye Occlusion, which simulate the shadow cast from the eyelids to prevent over-exposure on the eyeballs.
