Intensity Controls the overall brightness and opacity of the individual effect.
Higher values produce a bright, more opaque effect, and lower values produces
a dim, transparent effect.
Glow Behind Gives the effect the ability to be displayed behind objects in
your scene.
Occlusion Determines how much the Lens Effects Scene Occlusion parameters
will affect the particular effect. The value entered determines what percentage
of occlusion set in the Lens Effects Globals panel will be applied.
Squeeze 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.
Use Source Color Mixes the source color of the light or object you are
applying the effect to and the color or mapping set in the Radial Color or
Circular Color parameters. A value of 0 uses only the values set in the Radial
Color 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 Radial 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 the Lens Effect.
You can also use bitmaps such as Gradient or Cellular to determine the radial
color.
Falloff Curve Displays the
Radial Falloff dialog on page 6455 in which you
can set weights for the colors used in Radial Color. By manipulating the Falloff
Curve you 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 by using four different color
swatches that are matched to the four quadrants of the effect. A map can also
be used to determine circular color.
Mix Mixes colors set in Radial Color and colors set in Circular Color. Setting
the spinner at 0 will only use values set in Radial Color while setting the
spinner at 100 will only use values set in Circular Color. Any value between
0 and 100 will mix between the two values.
