Sheen Weight
An energy-conserving Sheen layer that can be used to approximate microfiber, cloth-like surfaces such as velvet and satin of varying roughness. Sheen is layered onto the diffuse component and its weight is determined with this attribute. Sheen can be thought of as the density or the combination of the density and length of the fibers.
