This page contains information about the V-Ray Ray Switch Texture in V-Ray for Modo.
The V-Ray Ray Switch texture gives a material a different color or texture when it is viewed through Shadows, GI, Reflections and Refractions. In the example shown here, a solid color was set for each channel of the V-Ray Switch Texture. The Default tex was set to red, the Shadow rays tex was set to green, the GI rays tex was set to blue, the Reflection rays tex was set to pink and the Refraction rays tex was set to yellow.
