After applying a map and setting its internal
parameters, you can adjust its output parameters
to determine the final appearance of the map.

color output, and don’t affect bump mapping (page
2–1506). Only the Invert toggle is considered; it
reverses the direction of the bumps.
Inter face
These con trols appear on the Output rollout for a
number of 2D and 3D maps:
Inver t—Reverses the hues of the map, like a
negative color photo. Default=off.
Clamp —When on, this par ameter limits the values
of the colors to no greater than 1.0. Turn this
on when you’re increasing the RGB Level, but
don’twantthemaptoappearself-illuminated.
Default=off.
Note: If you set the RGB Offset to a value greater
than 1.0 while Clamp is on, all colors become
white.
Alpha from R GB Intensity—When on, an alpha
channel is generated based on the intensit y of
the RGB channels in the m ap. Black becomes
transparent and white becomes opaque.
Intermediate values are translucen t according to
their intensity. Default=off.
Enable Color Ma p—Tu r n on to u se th e Color Map.
See “Color Map group.” Default=off.
Outpu t A mount —Controls the amount of the
map being mixed into a composite material.
Affects t he saturation and alpha va lue of the m ap.
Default=1.0.
RGB Offset—Adds to the RGB values of the m ap
colors by the amount set by the spinner, which
affects the tonal value of the colors. Eventually
the map becomes white and self-illuminated.
Lowering the value decreases the tonal value
toward black. Default=0.0.
RG B Level—MultipliestheRGBvaluesofthemap
colors by the amount set by the spinner, which
affects the saturation of the color. Eventually the
map becomes f u lly saturated and self-illuminated
(page 3–1009). L ower ing the value decreases
the saturation and makes the map colors g rayer.
Default=1.0.
Bump Amount—Adjusts the amount of bumpiness.
This value has an effect only when the map is used
as a bump m ap. Default=1.0.
Fo r example, suppose you hav e a map instanced
for both the Diffuse and the Bump components.
