Bias Setting depends on which shadow type is selected. In general, bias moves
the shadow toward or away from the shadow-casting object. See
Shadow Map
Parameters
on page 5135 and Ray-Traced Shadow Parameters on page 5133 for
specific effects.
Sm. Range For shadow-mapped shadows, sets the Sample Range value. See
Shadow Map Parameters on page 5135. This value has no effect for ray-traced
shadows. Default=4.0.
Transp. (Transparency) When on, turns on transparency for advanced
ray-traced and area shadows. Has no effect on shadow-mapped or standard
ray-traced shadows. Default=off.
The shadow transparency control is on the
Optimizations rollout on page 5130.
Int. (Integrity) For advanced ray-traced shadows or area shadows, sets the
Shadow Integrity. See Advanced Ray-Traced Parameters Rollout on page 5118
or
Area Shadows Rollout on page 5122. Default=1.
Qual. (Quality) For advanced ray-traced shadows or area shadows, sets the
Shadow Quality. See
Advanced Ray-Traced Parameters Rollout on page 5118 or
Area Shadows Rollout on page 5122. Default=2.
Decay (Standard Lights only.) Sets the type of decay: None, Inverse, or Inverse
Square. See Attenuation Parameters on page 5083. Default=None.
Start (Standard lights only.) Sets the start range for decay. See
Attenuation
Parameters
on page 5083. Default=0.0.
Length (Photometric lights only.) Sets the Length value for Line and Rectangle
photometric lights. See Shape/Area Shadows Rollout on page 5040.
Width (Photometric lights only.) Sets the Width value for Rectangle
photometric lights. See
Shape/Area Shadows Rollout on page 5040 .
Photometric Lights
Photometric lights use
photometric on page 8088 (light energy) values that
enable you to more accurately define lights as they would be in the real world.
You can create lights with various distribution and color characteristics, or
import specific photometric files available from lighting manufacturers.
NOTE Photometric lights always attenuate using an inverse-square falloff, and
rely on your scene using realistic units.
