Layer Group

The Layer Group node adds more than one MaterialThe representation of the surface or volume properties of an object. Layer type to an existing Material through the Material's Layer input pin. 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 Material Layers. The Layers are based on components used in previous OctaneRender^® Materials.

Using this set of unique Layers, OctaneRender^® lets you recreate complex Materials in a physically-based manner, as opposed to manually mixing materialsUsed to mix any two material types. together.

The following Material Layer nodes are available:

• Diffuse Layer - Used for dull, non-reflective materials.
• 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 Layers can connect to the Layered Material, Layer Group, or Material Layer pins on standard Materials.
