Octane Layers

Layer materials let 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, you can recreate complex Materials in a physically-based manner, as opposed to manually mixing MaterialsUsed to mix any two material types. together.

Figure 1: The Types of Layers

The following Layer nodes are available:

DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters. Layer - Creates dull, non-reflective Materials.
Material Layer Group - Adds multiple Layers to existing Materials.
Metallic Layer - Creates reflective Materials.
Sheen Layer - Simulates the grazing coloration in fabrics.
SpecularAmount of specular reflection, or the mirror-like reflection of light photons at the same angle. Used for transparent materials such as glass and water. Layer - Creates shiny Materials like plastic, or clear Materials like glass.
