Example: Using GI Override

This example shows how the use of a GI material override affects the rendering.

Example: Using the Reflection Override

The following example uses a very simple project. It contains five chairs, a light source, and a studio type environment. Each chair has an Override material assigned, but only the Base Material is active. The rendered chairs are the same in their diffuse colors and reflections.

...

Example: Using the Refraction Override

The next render is even more complex as the chairs' Override Refraction Material is activated as well. From left to right follow: a blue and a red diffuse color. Those materials are set so that when seen through refraction, V-Ray considers and renders the objects with them. As you can see the Reflection materials are still affecting the render image. If you take a closer look at the glass chairs' edges you will notice the green reflection, which is actually the reflection material of the right chair. While V-Ray had been tracing the rays on the chairs' surfaces, those polygons on the edges had first captured a reflection, so that's why there are green traces.
