The Multiresolution Adaptive Antialiaser dialog
changes settings for the Ray trace material and
maps Multiresolution Adaptive antialiaser. You
can use this dialog either globally, from the
Global Raytracer Settings dialog ( page 2–1528) ,or
locally, from the Raytracer Controls rollout (page
2–1521). When you locally change settings for an
antialiaser, you don’t affect the global settings for
that antialiaser.
Interfa ce
Adaptive Control group
Initial R ays—Sets the initial number of rays cast per
pixel. Default=4.
Threshold—Determines the sensit ivity of the
adaptation algorithm. It can range from 0 to 1,
where 0 always casts the maximum number of rays
and 1 always casts only the minimum number of
rays. Default=0.1.
Max. R ays (Maximum Rays)—Sets the maximum
number of rays the algorithm will cast. Default=32.
Blur / Defocus (Distance B lur) group
Blur Offset is similar to blur offset (page 3–918) for
bitmaps, whi le Defocusing is based on distance.
Blur Offset—Affectsthesharpnessorblurriness
of the reflections or refractions without regard
to distance. You can use Blur Offset to soften or
defocus the details of a reflection or refraction.
The value is specified in pixels. Default=0.0.
Tip: The default Blur Offset setting usually
produces good results. If you see aliasing in
reflections or refractions, increase its value in
increments of 0 .5 until the aliasing goes away.
