• Amount s pinner—The spinner at the left sets
the amount of intensity mapping to use. At
100.0, intensit y mapping has its greatest effect;
at lower amounts, the effect is less pronounced;
at 0.0, the map has no effect; and at values
less than 0.0, the material is dimmed. Range:
–100.0 to 100.0.
•
On/of f—The check box between the spinner
and the map button is an on/off switch. When
on, the map is used in the material. When off,
the map is not used.
Cu tout con trols—These controls assign a cutout
map (page 2–1383)
to the material. To assign a
map, click the oblong button (labeled “None” by
default).ThisdisplaystheMaterial/MapBrowser.

an additional dialog prompts you to choose the
particular bitmap file to use.

• Amount s pinner—The spinner at the left sets
theamountofcutoutmappingtouse. This
value is a percentage: at 100.0, the map has
its fu l l effect; lower amounts have the effect
of darkening the map, reducing its effect and
increasing transparency. At 0.0, the map is
completely black, making objects with this
material completely transparent.
•
On/of f—The check box between the spinner
and the map button is an on/off switch. When
on, the map is used in the material. When off,
the map is not used.

When you create a new Architectura l material
(page 2–1376)
or edit an exist ing one, the sett ings
on the Adjust Radiosity rollout let you adjust how
the material behaves in a
radiosity solution (page
3–50)
.
Obtaining a B etter Image
Materials with a bright diffuse color or high
shininess can be high ly reflective. This can lead to
overexposed or washed-out radiosit y solutions.
In general, the best way to adjust this is to reduce
theHSVValue(V)ofamaterial’sdiffusecolor;
or, for a material with a diffuse map, reduce the
map’s RGB level. In some situations, the controls
on this rollout can improve the appearance of the
radiosity solution. Examples of situations where
the material’s radiosit y settings can help include
color bleeding and large dark areas:
• YoumightwanttoreduceReflectanceScaleor
Color Bleed Scale when a large area of color
(for example, a red carpet in a room with w hite
walls) create s excessive color bleeding. This
mightbephysicallyaccurate,buttheeyeadjusts
for such effects, and the radiosit y result might
look better with less reflectance or less color
bleeding.
