The layered material system lets you construct complex materials 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 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 materialsUsed to mix any two material types. together.
The 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 is used for dull, non-reflective materials. See the Diffuse Material topic in this manual for more information. Material Layers can connect to the Layered Material, Layer Group, or Material Layer pins on standard materials (Figure 1).
Figure 1: Diffuse and 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. layers are mixed using the Layer Group node
Diffuse - The layer's diffuse color.
TransmissionA surface characteristic that determines if light may pass through a surface volume. - The layer's transmission color. This can be used for thin translucent objects.
BRDF Model - Determines how light reflects or refracts. See the BRDF Models topic in this manual for more information.
Roughness - The Diffuse layer's roughness. High values simulate very rough surfaces like sandpaper or clay.
Bump - Simulates a relief by using a Greyscale texture interpreted as a Height map for the layer.
Normal - Distorts layer normals using an RGB image.
Layer Opacity - Controls the layer opacity with a Greyscale texture.
Export Octane Material - Opens a dialog window that provides options for exporting the Material to ORBXThe ORBX file format is the best way to transfer scene files from 3D Authoring software programs that use the Octane Plug-in such as Octane for Maya, Octane for Cinema 4D, or OctaneRender Standalone. This format is more efficient than FBX when working with Octane specific data as it provides a flexible, application independent format. ORBX is a container format that includes all animation data, models, textures etc. that is needed to transfer an Octane scene from one application to another., the Local DB, or the Live DB.
