The Composite material node mixes several materials using masks (Figure 1). This is much cleaner than using several chained Mix materials. If a mask is not connected, the material's Opacity is used. The first MaterialThe representation of the surface or volume properties of an object. pin becomes the base layer.
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 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. materials connected to a Composite material node
DisplacementThe process of utilizing a 2D texture map to generate 3D surface relief. As opposed to bump and normal mapping, Displacement mapping does not only provide the illusion of depth but it effectively displaces the actual geometric position of points over the textured surface. - Displacement for the Composite Material surface.
Add Input - Adds a new Material input to the end of the Node.
Remove Input - Removes the last Material input.
Comp Material - The Material input. When several MaterialsA set of attributes or parameters that describe surface characteristics. are used, the first Material pin becomes the base layer.
Mask Tx - Controls the Material’s opacity using an Input map. If a mask is not connected, then OctaneRender® uses the Material's opacity.
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.
