An energy conserving, Marschner-style transmission component (also known as TT). Since this models light shining through hair before getting to the camera, the hair must be between the camera and the light source for the transmission effect to be visible. This hair shading component is more important when doing rim lighting on hair or fur.

Transmission Color

The color of the transmission component.

Transmission Spread

multiplier on the transmission effect's spread: a smaller value produces a more focused, brighter effect. The default spread is 1.0, which corresponds to a realistic look for blonde hair. Reasonable values should be within the 0.5 to 5.0 range.
