Octane for 3dsmax

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 material pin becomes the base layer.

Composite Material Parameters

Displacement - Displacement for the Composite Material surface.

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.

Add Input - Adds a new Material input to the end of the Node.

Remove Input - Removes the last Material input.

Material 1, 2, ... - The Material inputs. When several materials are used, the first material pin becomes the base layer.

Material 1, 2....Mask - 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 ORBX, the Local DB, or the Live DB. 

Convert - Provides options for converting this material to other Octane-specific material types.
