solid-color background, and then composite the rendered scene with the
background image.
■ Sometimes when you render objects that have zero thickness, or an Extrude
modifier with zero thickness, the mental ray renderer generates rendering
artifacts that appear as streaks. In some cases, you can fix this by turning
on Force 2-Sided in the Render Scene dialog's Common Parameters rollout.
If the streaks persist, give the object or the Extrude modifier a nonzero
thickness.

Procedures
To use the mental ray renderer:
1 Choose Rendering menu > Render. The Render Scene dialog displays.
2 On the Common panel, open the Assign Renderer rollout, then click the
“...” button for the Production renderer.
A Choose Renderer dialog is displayed.
3 On the Choose Renderer dialog, click to select mental ray Renderer, and
then click OK.
Now when you render, the Render Scene dialog appears with the mental ray
controls. You can choose to render the scene with the built-in mental ray
renderer, or simply to translate the scene and save it in a
.mi on page 7848 file
that you can render later, perhaps on a different system. Controls for choosing
