# Sheen

Sheen is mainly used for complex fabrics such as velvet. It allows you to simulate reflection of the light on the threads that differs based on the angle you are looking at it.  

**Sheen color:** control the colour and intensity of the sheen effect with a RGB value or texture.

**Sheen roughness:** control the light reflection on the sheen effect with the input value or with a grayscale texture.
