Flag Material as Opaque—When on, indicates
that the material is fully opaque. This tells the
mental ray renderer that it doesn’t need to process
transparenc y for this material, or to use the
shadow shader (if one has been assig ned). This
can improve rendering time. Default=off.

Material Editor > Type button > Material/Map Browser >
mental ray > Advanced Shaders rollout
Note: The mental ray material does not appear in
the Browser unless you have enabled the mental ray
extensions by using the mental ray Preferences panel. In
addition, you can’t assign shaders to the o ptions in this
rollout unless the mental ray renderer is the currently
active renderer.
The mental ray material lets you create a material
exclusively for use by the
mental ray renderer (page
3–77)
. The Advanced Shaders rollout provides
controls for two component shaders that aren’t
always used.
Inter face
Each shader component has a toggle at the left of
itsname.Whenthetoggleison,theshaderisused
inrendering.Whenthetoggleisoff,theshaderis
not used, even if it has been assigned. Clicking the
button to the right of the component name displays
the
Material/Map Browser (page 2–1256)
so you
can assign a p articular shader to t he component.
Co nto ur—Assigns a
contour shader (p age 3–95)
to the material.
The contour component can be assigned the
following shaders:

Light Map—Assigns a light map shader to the
material.
