The Mix material mixes any two material types, including other Mix materials. It accepts any two Material nodes as inputs, and you control the mix amount by a value, color, or texture.

Parameters

    • Amount - Controls the blend between the first and second material inputs.
    • First material - Input for the first material node for blending.
    • Second material - Input for the second material node for blending.
    • Displacement - Use any of the Octane Displacement node. The two Materials' individual displacements are not used when you connect them to a Mix material node. Instead, the Mix material has its own Displacement input.

    • 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.
