Glow Lens Effect 223
Occlusion—
Determines how much the Lens
Effects Scene O cclusion parameters wil l affect the
particular effect. The value entered determines
what percentage of occlusion set in the Lens Effects
Globals panel will be applied.
Sq ueeze—Determines whether the effect will
be squeezed. When activated the effect will be
squeezed according to Lens Effects Globals under
the Parameters panel in the Squeeze spinner.
UseSourceColor—Mixes the source color of the
lightorobjectyouareapplyingtheeffecttoand
the color or mapping set in the Radial Color or
Circular Color parameters. A v alue of 0 uses only
the values set in the Radial C olor and Circular
Color parameters while a value of 100 uses only the
light or objects source color. Any value between 0
and 100 will render a mix between the source color
and the effect’s color parameters.
Radial Color group
The Radia l Color settings affect the inner and
outer colors of the effect. You can set the color
swatches to set the inner and outer colors of t he
Lens Effect. You can also use bitmaps such as
Gradient or Cellular to determine the radial color.
Fa lloff Cur ve—Displays the Radial Falloff dialog
(page 3–253)
in which you can set weights for the
colors used in Radial Color. By manipulating the
Falloff Curve y ou can make the effect use more of
one color or map than the other. You can also use
a map to determine the falloff when a light is used
as a Lens Effects source.
Circular Color group
Circular Color determines the color of the effect
byusingfourdifferentcolorswatchesthatare
matched to the four quadrants of the effect. A map

between the two values.
Fa lloff Curve—Displays the Circular Falloff dialog
(page 3–250)
in which you can set weights for the
colors used in Circular Color. By manipulating the
Falloff Curve y ou can make the effect use more of
one color or map than another. You can also use a
map to determine the fal loff when a light is used
as a Lens Effects source.
Radial Size group
Determines the radial size around the particular
Lens Effe ct. Clicking the Size Curve button
displays the
Radial Size dialog (page 3–255) .
Using the Radial Size dia log you can create points

to determine where the effect should be placed
around the light or object. You can also use a map
