The VRayUserColor texture can be used to read user-defined object properties from the current material and convert them to a color value. This allows you to use the same shading network on several different objects in the scene, but to control various aspects of the material through user-defined properties. For more information about Visit the User Attributes Workflow page for information and tutorials on user-defined properties(i.e., User Attributes), see the User Attributes Workflow page.
This texture can also read mesh color sets, UV sets, and extra channel information from from VRayProxy objects.
The Example on the right uses VRayUserColor to control the diffuse value on a single V-Ray Material.
