New AFC Hair shader for FiberFX
AFC stands for Artist-Friendly Controls. AFC Hair, like other hair materials, is also a dielectric material. The specular settings are divided into two sections. Primary is concerned with reflections of the front side of the stroke. The secondary specular is for the reflection bounced off the backside of the stroke, through what's called the cortex color inside the hair cylinder.
