HotSpot/Falloff group
Angle Separation—Lo cks the spotlight hotspot
(page 3–1048)
and falloff (page 3–1048) cones
at the angle separ ation defined by the spinner
(degrees). This option constrains the hotspot

Background group
Don’t Antialias Against B ack ground—Ensures
that the edges of rendered geometry aren’t
antialiased against the background. The inside
of the geometr y is still antialiased. Keep this
control off unless you’re creating sprites for game
development, or require special compositing
techniques because the background will not be
rendered. In these cases, turning on this option
helps avoid generating alpha antialiasing on the
outlines of the geometry. Default=off.
Note: You must be rendering against a black
background if Don’t Antialias Against Background
is turned on.
Filter B ackground—Cont rols whether or not a
background image is affected by the Renderer’s
antialiasing Filter. See Plate Match /MAX R2.5/VIZ
R2 Filter Types in
Default Scanline Renderer
Rollout (page 3–37)
for detailed information of
filtering background and antialiasing.
Use Envir onment Alpha —Controlswhetherornot
the renderer uses the environment map’s alpha
channel in created the alpha for the rendered
image. If Use Environment Alpha is turned off,
the background is completely trans parent. If it
is turned on, the alpha of the resulting image is
a combination of the scene and image’s alpha.
Note that only background images with alpha
channels or black backgrounds are supported
when compositing in other programs such as
Photoshop.
DefaultAmbientLightColorgroup
Click the color swatch to change the default
ambient light (page 3–1002) color for renderings.

shadows in the scene.
Output File Sequencing group
Nth S er ia l Number ing—Specifies whether output
frame files generated using a frame-step value
other than 1 are numbered sequentially (on) or
according to their true frame numbers (off).
Render Termination Alert group
Beep—Beeps when the rendering has finished. You
can set the frequency and the durat ion.
Play Sound—Plays a sound file when the rendering
has finished.
Cho ose S o un d —Opens the Open Sound browser
dialog, select a sound file using the browser. You
can test sound files with the Play button in the
Open Sound dialog. Press ESC to tur n off the
sound.
GBuffer Layers group
Maximum Number—Limits the number of layers
that are stored in the G- buffer dur ing rendering.
Default=10; Range=1 to 1000.
Memory requirements may dictate that you limit
thenumberofG-bufferlayers.TheRLAandRLF
image formats, used for compositing, can store
many G-buffers for object Z buffer information,
material ID, tr ansparency and so on.
Multi-threading group
On—Causes the s oftware to treat the rendering
task as separate threads. This option works
w ith multiprocessor systems. Each processor in
your computer handles a different thread, which
makes full use of available processing power and
speeds up rendering to its maximum level. When
