All Selects all source pixels in the scene and applies the Lens Effect to them.
Edge Selects all source pixels along a boundary edge and applies the Lens
Effect to them. Applying a Lens Effect along the edges of objects produces a
soft halo that exists on both inside and outside edges of your object.
Perim(eter) Alpha Applies the Lens Effect only to the perimeter of an object
based on its alpha channel. Selecting this option applies the effect only on
the outside of an object without any spill on the interior. Whereas filtering
by Edge produces a spill onto the object, Perimeter Alpha keeps all of the edges
clean because it relies on the scene alpha channel to derive its effect.
Perim(eter) Applies the Lens Effect only to the perimeter of an object based
on Edge interference. Although not as precise as Perimeter Alpha, you might
need to use the Perimeter option at times when the alpha channel is
unavailable.
Bright Filters the source objects based on their brightness values. The effect
is only applied to objects with a brightness above the spinner setting This
option can be inverted by clicking the I button next to the spinner
Hue Filters the source objects by their hue. Select the hue by clicking the
color swatch next to the spinner. You can choose hue values from 0 to 255.
The spinner beside the Hue color swatch lets you enter a variance level so that
the glow can find several different hues in the same range as the chosen color
Additional Effects group
Additional Effects allows you to apply maps such as Noise to your Lens Effect.
You can display the Material/Map browser by clicking the long button next
to the Apply check box.
Apply Applies the selected map when activated.
Radial Density Determines where and how much you would like the
additional effects applied. Clicking the Radial Density button displays the
Radial Density dialog on page 6453 . Using the Radial Density dialog you can
create points on a line and move those points along a graph to determine
where the additional effect should be placed around the light. You can also
use a map to determine where the additional effect should be placed.
