I am working on some next-gen characters utilizing the fantastic rendering features found in 4.12. I have extensively watched through Epic’s character rendering stream, and looked through the content examples–all of which have been extremely helpful. However, one topic not really covered is the rendering of eyelashes and eyebrows.
What is Epic’s material setup for eyelashes and eyebrows? I assumed it was a simple translucent material, but my implementation has a lot of lighting artifacts.
My setup is the following:
However it doesn’t completely respect shadows (just a simple test map with stationary spot lights):
Now my characters are dynamic and designed to be customized, so you can swap out eyebrows and adjust colors and such. Unfortunately, this means I can’t really paint eyebrows in the texture maps and they must be separate meshes translucently blended on top.
