Reflection dimming
Above: None
Below: 0.0 (100% dimming)
Apply—Turn on to use reflection dimming.
When off, the reflection-mapped material is not
affected by the presence or absence of direct light.
Default=off.
Dim Level —The amount of dimming that takes
place in shadow. At 0.0, the reflection map is
completely dark in shadow. At 0.5, the reflection
map is half dimmed. At 1.0, the reflection map is
not dimmed a nd the material appears as if Apply
were tur ned off. Default=0.0.
Refl. Level—Affects the intensity of the reflection
that is not in shadow. The Reflection Level value
multiplies the illumination level of the lit area
of the reflection, to compensate for dimming.
In most cases, the default value of 3.0 keeps the
reflect ion in the lit area at about the same level it
would appear if reflection dimming were not on.

assign maps (page 3–968) to various components
of the material.
You can choose from a large variety of map types.
To find descriptions of the se types, and how to set
their par ameters, see Map Types (page 2–1617) .
Assigning the Same Ma p to Different
Par a met er s
Applying the s ame map to different parameters is
useful in some cases. For example, using a pattern
to map both self-illumination and opacity can
make the pattern appear to glow and hover in
space.
Blending Map Amounts for Opacity and
Ot her M at eri al Component s
When you map a scalar componen t (such as
Specular Level, Glossiness, Self-Illumination,
and Opacit y), the component’s value in the Basic
Parameters (page 2–1470) rollout is blended with
its associated map Amount in the Maps rollout.
For example, when the Opacity spinner is set to
0, the map Amount spinner completely controls
Opacity. That is, reducing the Amount value
increases the transparency of the entire surface.
On the other hand, when Opacity is 100, reducing
the map’s Amount value increases the opacity
oftheentiresurface. YoucanadjustaChecker
Opacity map so that the opaque areas remain
opaque, while the transparent areas become
semi-transparent.
Other scalar components behave in the same way.
