Advanced Shaders Rollout (mental ray Material)

The Advanced Shaders rollout provides controls for two component shaders that aren't always used.

Interface

Each shader component has a toggle at the left of its name. When the toggle is on, the shader is used in rendering. When the toggle is off, the shader is not used, even if it has been assigned. Clicking the button to the right of the component name displays the Material/Map Browser so you can assign a particular shader to the component.

Contour

Assigns a contour shader to the material.

The contour component can be assigned the following shaders:

Note: Contours don't render unless you have also enabled them on the Render Setup dialog Renderer panel Camera Effects rollout.
Light Map

Assigns a light map shader to the material.

Note: No light map shaders are provided with 3ds Max. This option is for users who have access to light map shaders via other shader libraries or custom shader code.
