The Override Material is a utility material provided with the V-Ray renderer. It allows a surface to look different depending on whether it is seen through reflections, refractions, or GI.

With this material, you get fine controls over the color bleeding, reflections, refractions, and shadows of the objects.

The example rendered here shows the use of the Override Material to create some interesting reflections and refractions of the chairs. Notice how the yellow chair changes its color when seen through a refractive material. The reflections of the colored chairs, seen on the floor, display variation of the colors as well.

This section lists input sockets that are not found in the Properties tab but only as inputs for the node.

Base Material – Input socket for the material V-Ray uses while rendering the object.

GI Material – Input socket for the material V-Ray uses while calculating the GI solution. See the Gi Material override example below for more information.

Reflect Material – Input socket for the material V-Ray uses when the object is seen in reflections.

Refraction Material – Input socket for the material V-Ray uses when the object is seen in refractions.

Shadow Material – Input socket for the material that is used to render shadows cast from the object.

For a much more complex scene, with lots of different geometry, shaders, textures, etc., using the VRayOverride material can be very helpful.
