Material Composite

The Composite material node mixes several materials using masks. This is much cleaner than using several chainedMix materials. If a mask is not connected, the material's Opacityis used. The first MaterialThe representation of the surface or volume properties of an object. pin becomes the base layer. The Composite material node can be accessed inside an Octane VOP Net node (Figure 1).

Composite Material Parameters

Custom AOV

Writes a mask to the specified custom AOV.

Custom AOV Channel

Determines whether the custom AOV is written to a specific color channel (R, G, or B) or to all the color channels.

Material Count

Adds a new Material input to the end of the 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.

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.

Material Mask

Controls the Material’s opacity using an Input map. If a mask is not connected, the Material's opacity is used.
