The layered material system lets you construct complex MaterialsA set of attributes or parameters that describe surface characteristics. that consist of a base layer and up to eight MaterialThe representation of the surface or volume properties of an object. Layers. The Layers are based on components used in previous OctaneRender® Materials. Using this set of unique Layers, OctaneRender® recreates complex Materials in a physically-based manner, as opposed to manually mixing MaterialsUsed to mix any two material types. together.
The Sheen layer simulates the grazing coloration or rim lighting in fabrics like velvet. It can also simulate layers of dust. See the Universal Material topic in this manual for more information. Material Layers can connect to the Layered Material, Layer Group, or Material Layer pins on standard Materials.
Figure 1: Sheen layer parameters
Sheen - The Sheen layer's color.
Roughness - The Sheen layer's roughness. Higher values spread the sheen color to larger parts of the surface.
Affect roughness - Override the roughness value of the base material with the Sheen roughness value.
Bump - Simulates a relief by using a Greyscale texture interpreted as a Height map for the layer.
Normal - Distorts Layer normals by using an RGB image.
Layer Opacity - Controls the Layer opacity with a Greyscale texture.
