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 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, 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 Metallic layer is used for highly reflective Materials that have colored reflections. For more information, see the Metallic Material topic in this manual. Material Layers can connect to the Layered Material, Layer Group, or Material Layer pins on standard Materials.
Figure 1: 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. and Metallic layers are mixed by using the Layer Group node
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. - The Layer's coating color.
BRDF Model - Determines how light reflects or refracts. See the BRDF Models topic in this manual for more information.
Roughness - Adjusts how rough the Metallic layer looks.
Anisotropy - The Metallic layer's anisotropy. A value of -1 is horizontal, while 1 is vertical. A value of 0 is isotropic.
Rotation - The Metallic anisotropic reflection's rotation.
Metallic Reflection Mode - This changes how OctaneRender® calculates reflectivity.
Index Of Refraction - Complex-valued IOR (n-k*i) controlling the specular reflection's Fresnel effect, where n = the refractive index and k = the attenuation or extinction coefficient. For RGB mode, the IOR for red light (650nm).
Index Of Refraction (Green) - For RGB mode, the IOR for red light (550nm).
Index Of Refraction (Blue) - For RGB mode, the IOR for red light (450nm).
Film Width - Sets the film coating's thickness.
Film IOR - Sets the film coating's Index Of Refraction.
Bump - Simulates a relief using a Greyscale texture interpreted as a Height map for the Layer.
Normal - Distorts the Layer normals using an RGB image.
Layer Opacity - Controls the Layer's 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.
