VRayMtl Sheen

The Sheen layer can be used for creation of cloth material, such as satin. You can find additional information on how to use them at Coat and Sheen Layers.

Sheen Color – Specifies the color.

Amount – Specifies how much the sheen layer overlays the diffuse color. The higher the amount, the more of the sheen color you get. See the Sheen Amount example below for more information.

Sheen Glossiness – Controls the sharpness of reflections. A value of 1.0 means all of the light reaches the diffuse color, and when the value is smaller, the cloth material looks glossier. See the Sheen Glossiness parameter below for more information.

Note that this rollout is renamed to Fuzz when the Shading Model is set to OpenPBR. The parameters function the same, except the Sheen glossiness parameter; it is renamed to Fuzz Roughness and controls the sharpness of the reflections in an opposite way. A value of 0.0 means that none of the light reaches the diffuse color, and when the value is larger, the cloth material looks glossier.

To find out why this is, read the OpenPBR article.

Example: Sheen Amount

This example shows how changing the amount of the sheen layer affects the material. Glossiness is set to its default value - 0.8.
