Ashraf Aiad continues previous posts on Mental Ray Production Library– Enabling mip Shaders .
“We can now start exploring the available new nodes. In this session we will have a closer look at how to use the mip Shaders, in particular the mip_rayswitch and mip_rayswitch_advanced. This Shader will act as a gateway for the outgoing rays that are bouncing of an object or an environment. For example you can change the color of the reflection of any giving object in the scene. It can also be used to alter environments.”
