Contour component of the mental ray Connection
rollout (page 2–1461) or a mental ray material (see
Advanced Shaders Rollout (mental ray Mater i al)
(page 2–1548)).
Note: Contour shading does not work with
distributed bucket rendering.
Enable—When on enables rendering of contours.
Default=off.
Click a button to change a shader assignment for
adjusting contours. A default is already assigned to
the three components, as the button labels indicate.
Contour Cont ra st—The contour contrast
component can be assig ned the following shader:

To adjust the settings for a shader assigned to one
of these components, drag the shader’s button to
an unused Mate rial Editor sample slot. Be sure to
choose Instance when prompted to use an instance
or a copy. (If you edit a copy of the shader , you will
have to drag the sample slot back to the shader
button on the Camera Effects rollout before you
seeanychangestakeeffect.)
Camera Shaders group
These controls let you assign mental ray camer a
shaders. Click a button to assign a shader to that
component. After a shader is assigned, its name
appears on the button. Use the toggle on the
left to temporarily disable a shader that has been
assigned.
