Raytraced R e fle ction and Refrac tion Antialiaser
group
Controls in this group let you override the global
antialiasing sett ings for raytraced maps and
materials. They are unavailable if antialiasing
is turned off globally. To turn on antialiasing
globally, choose Rendering > Raytrace Globals to
display the
Global Rayt racer Settings dialog (page
2–1369)
.
On—When on, uses antialiasing.
Default=unavailable unless global antialiasing is
on; on if global antialiasing is turned on.
Drop-down list—Chooses which antialiasing
settings to use. There are three alternatives:
Use Global Antialiasing S ettings—(The default.)
Uses the global antialiasing sett ings.
Fa st Adaptive Antialiaser—Uses the Fast Adaptive
antialiaser, regardless of the global setting.
Multiresolution Adaptive A ntialiaser—Uses the
Multiresolution Adaptive antialiaser, regardless of
the global setting .
...—The button with the ellipsis to the right of
the drop-down list displays another dialog to let
you set antialiasing controls locally. The dialog
displayed depends on which alternative you chose
in the drop-down list, as follows:
Use Global Antialiasing S ettings—Clicking ...
displays the
GlobalRaytracerSettingsdialog(page
2–1369)
.
Fa st Adaptive Antialia ser—Clicking ... displays the
Fast Adaptive Antialiaser dialog (page 2–1374)
.
Multiresolution Adaptive Antialiaser—Clicking ...
displays the
M ultiresolution Adaptive Antialiaser
dialog (page 2–1375)
.
When you change settings for an antialiaser
locally, you don’t affect the global settings for that
antialiaser.
Raytrace Maps Rollout
Material Editor > Type button > Material/Map Browser >
Raytrace material > M aps rollout
As w ith a standard material, the Maps rollout
for a
Raytrace material (page 2–1353)
contains
map buttons f or the components of the Raytrace
material that can be mapped.
You can choose from a large var iety of m ap t ypes.
See
Map Types (page 2–1426)
to fi nd descr iptions
of these types, and how to set their parameters.
Assigning the Same Map to Different
Par a met er s
Applying the same map to different parameters is
useful in some cases. For example, using a pattern
as both a self-illumination map and an opacity
map can make the pattern appear to glow and
hover in space.
Blending Map Amounts for Opacity and
Ot her Ma ter ia l Component s
The Specular Level, Glossiness, Self-Illumination,
and Opacity values in the four spinners in the
Basic Parameters rollout are blended with their
associated map Amount va lues in the Maps rollout.
When the Opacity spinner is set to 0, the m ap
Amount spinner completely controls Opacity.
That is, reducing the Amount value increases the
transparencyoftheentiresurface.Ontheother
hand, when Opacity is 100, reducing the map
Amountvalueincreasestheopacityoftheareas
where the Opacity map is less than 1. For example,
you can now adjust a Checker Opacity map so that
the solid areas remain solid, w hi le the clear areas
are semi-transparent.
The Specular Level, Glossiness, and
Self-Illumination channels all behave in the
same way. A setting of 100 applies all of the map; a
setting of 0 is the equivalent of turning the map off.
