Digital Human Eye Occlusion Shader (New for v3.3)

In order to achieve the Real-Human eye effect, CC3 Base+ character add two new eye elements: 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 junction 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.
