• Turn on Back Face Culling and turn off Back Bevels to speed your renders—see
“Adding Bevels and Extrusions” on page 332.
Lighting in 3D Space
You can apply up to three separate lights to the effect. These lights are modeled as non-
directional point sources that you can position in 3D space. You can also adjust and animate
the lights’ color and intensity, and control the amount of ambient light on the entire object.
For detailed information on the Lights tab parameters, see “Lights Tab (in 3D Space)” on
page 373.
Tips for Using Lighting Controls
You can move the lights in 3D space to accent the front or back faces, bevels or extrusions,
and use multiple lights to create more complex, multi-colored lighting effects.
To highlight the face of an object:
• In the Lights tab, use a positive Distance value to place the light in front of the object.
To backlight the object:
• In the Lights tab, use a negative Distance value to place the light behind the object.
The object is spun slightly, so
the source is positioned to the
left to accentuate the face.
