The Hair BSDF node is used to add shading for Hair.
Color of the hair.
Controls the way the light is rotated (angular shift) for the reflection/transmission.
- Roughness U/V
Controls the roughness in the direction light is skewed, and perpendicular to it.
There are two components that can be used to control the look of the hair. Usually you are going to want each of these and use a Mix Node.
The light that bounces off the surface of the hair.
The light that passes through the hair and exits on the other side.
Standard shader output.
