Octane for 3dsmax

The Color Vertex Attribute texture works in conjunction with the 3ds Max® Vertex Paint modifier. This texture node displays vertex paint data on native OctaneRender® Materials. A mesh object will need to have the Octane Geometry Properties modifier applied to successfully read the Map Channel properties correctly.

Scene objects display the Color Vertex Attribute node if you set them to Movable Proxy in the Octane Object Properties window (figure 2).

After painting the object surface with the Vertex Paint modifier, connect the Color Vertex Attribute node where appropriate in the object's shader node network (figure 3).

The Vertex Paint modifier's default Map Channel for storing the color data is 0. Specify this in the Color Vertex Attribute node's Name parameter.
