Digital Human Tear Line Shader
In order to create realistic eyes, CC5 + base characters enhance the eye elements: Eye Occlusion and Tear Line. The Eye Occlusion simulates the shadows cast from the eyelids while the Tear Line
emulates the reflections of the tears at the line of contact between the eyeballs and the eyelids.
The mesh layer under the Eye Occlusion is the Tear Line mesh, which simulate the moisture and the tear reflectivity on the eyeballs and the tear ducts.

Although the tearline texture remains unchanged, its UV mapping has been adjusted:

For the CC 4 character's tearline, the normal map tiling is unevenly distributed. |
More realistic normal tiling distribution result. |
