Sheen#
Sheen simulates soft, velvet-like surface reflections common in fabrics and textiles. It adds angle-dependent color and roughness to create microfiber scattering effects typically seen in materials like cloth, carbon fiber, and velvet
Parameters
This layer creates an energy-conserving retro-reflective sheen BRDF. Sheen simulates surface micro-fibers, with axes oriented parallel to the surface normal, creating specular highlights at grazing angles.
Sheen can create soft backscattering materials like fine powder, dust, satin, leaf, and peach fuzz on the skin.
Weight
This parameter sets the density and length of micro-fibers. At 0.0, sheen has no effects.

Color
This parameter tints the color of the sheen, i.e., micro-fibers.
|
|
Roughness
This parameter sets the sheen effect roughness. Micro-fibers diverge more from the “surface normal” direction at a higher value, resulting in a softer look.
