Octane Composite Material
Last modified: 10 March 2025The Composite material node mixes several materials using masks. This is more efficient than using several chained Mix materials since a single mix material can only mix two materials together. If a mask is not connected, the material's Opacity is used. The first Material pin becomes the base layer.
Composite Material Node
Displacement - This attribute can be used to add a displacement texture to the material.
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 X Enabled - Allow a material to be turned on and off.
Material X - The Material input. When several Materials are used, the first Material pin becomes the base layer.
Material X Mask - Controls the Material's opacity using an Input map. If a mask is not connected, the Material's opacity is used.
Parameters
The Composite Material node allows up to 8 materials to be combined using masks.
