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.

Figure 1: Sheen layer Node

Parameters

    • Compatibility version - The Octane version that the behavior of this node should match.
    • Enabled - Whether this layer is applied or skipped.
    • 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 - The percentage of roughness affecting subsequent layers' roughness.
    • Bump - Creates fine details on the material’s surface using a Procedural or Image texture. Often a Greyscale image texture connects to this parameter - light areas of the texture indicate protruding bumps, and dark areas indicate indentation. You can adjust the Bump map's strength by adjusting the Power or Gamma values on the Image texture node.
    • Bump height - The height represented by a normalized value of 1.0 in the bump texture. 0 disables bump mapping, negative values will invert the bump map.
    • Normal - Distorts Layer normals by using an RGB image.
    • Layer Opacity - Controls the Layer opacity with a Greyscale texture.
