The Sheen rollout is part of the Generic material's parameters.

Sheen

Available only in Advanced mode.

Sheen Color – Specifies the color of the sheen layer. Black color disables the effect.

Sheen Glossiness – Available when the Surface control option is set to Use Glossiness. Controls the sharpness of reflection. A value of 1.0 means all of the light reaches the diffuse color, whereas when the value is smaller, the cloth material looks glossier. See the Sheen Glossiness example below.

Sheen Roughness– Available when the Surface control option is set to Use Roughness. Controls the sharpness of reflection. A value of 0.0 means all of the light reaches the diffuse color, whereas when the value is higher, the cloth material looks glossier.

The Sheen layer can be used for creation of cloth materials, such as satin. It is a top reflective layer to the diffuse color.
 



Example: Sheen Glossiness


 

This example shows how changing the glossiness parameter of the sheen layer affects the material. A smaller value makes the sheen layer reflect most of the light. Increasing the value allows more light to reach the diffuse component.
