The Layered material node constructs complex materials that consist of a base layer and up to eight Material Layers. You can create complex materials in a physically-based manner, as opposed to manually mixing materials together. By default a Diffuse material is listed as the base material. Other materials can be selected as the base material.

Layered Material Parameters

Add Layer - Adds a new Layer input to the end of the Node. You can add up to eight Layer inputs.

Base Material - The material that sits below any additional Material Layers.

Layer 1-8 - The Material Layer inputs.

With the Layered material, you are given all Material Layers used in OctaneRender®, allowing you to reconstruct pre-existing Octane materials or your own uber-material.
