Material Layers
The Layered material system lets you construct complex materials that consist of a base layer and up to eight Material Layers. The Layers are based on components used in previous Octane materials. Using this set of unique layers, OctaneRender® now lets you recreate complex materials in a physically-based manner, as opposed to manually mixing materials together.
The following Material Layer nodes are available:
- Diffuse Layer - Used for dull, non-reflective materials.
 - Material Layer Group - Adds multiple Material Layers to existing materials.
 - Metallic Layer - Used for highly reflective materials.
 - Sheen Layer - Simulates the grazing coloration in fabrics.
 - Specular Layer - Used for shiny materials like plastic, or clear materials like glass.
 - Material Layer Switch - This node can be used to connect two or more material layer types to one input on a Layered Material node.

Material Layers can connect to the Layered Material, Layer Group, or Material Layer pins on standard materials.
