Segments Specifies the number of segments that form the main lightning bolt. Higher
values produce more detail but reduce the smoothness of motion.
Amplitude Specifies the size of undulations in the lightning bolt as a percentage of the
layer width.
Detail Level, Detail Amplitude Specify how much detail is added to the lightning bolt
and any branches. For Detail Level, typical values are between 2 and 3. For Detail
Amplitude, a typical value is 0.3. Higher values for either control are best for still images
but tend to obscure animation.
Branching Specifies the amount of forking that appears at the ends of bolt segments. A
value of 0 produces no branching; a value of 1.0 produces branching at every segment.
Rebranching Specifies the amount of branching from branches. Higher values produce
tree-like lightning bolts.

Branch Angle Specifies the size of the angle between a branch and the main lightning
bolt.
Branch Seg. Length Specifies the length of each branch segment as a fraction of the
average length of the segments in the lightning bolt.
Branch Segments Specifies the maximum number of segments for each branch. To
produce long branches, specify higher values for both the branch segment length and the
branch segments.
Branch Width Specifies the average width of each branch as a fraction of the width of
the lightning bolt.
Adjust the following controls for the Lightning effect:
Speed Specifies how fast the lightning bolt undulates.
Stability Determines how closely the lightning undulates along the line defined by the
start and end points. Lower values keep the lightning bolt close to the line; higher values
create significant bouncing. Use Stability with Pull Force to simulate a Jacob’s Ladder
effect and cause the lightning bolt to snap back to a position along the start line after it
has been pulled in the Pull Force direction. A Stability value that is too low does not allow
the lightning to be stretched into an arc before it snaps back; a value that is too high lets
the lightning bolt bounce around.
Fixed Endpoint Determines whether the end point of the lightning bolt remains fixed in
place. If this control is not selected, the end of the bolt undulates around the end point.
Width, Width Variation Specify the width of the main lightning bolt and how much the
width of different segments can vary. Width changes are randomized. A value of 0
produces no width changes; a value of 1 produces the maximum width changes.
Core Width Specifies the width of the inner glow, as specified by the Inside Color value.
The Core Width is relative to the total width of the lightning bolt.
Outside Color, Inside Color Specify the colors used for the lightning bolt’s outer and
inner glows. Because the Lightning effect adds these colors on top of existing colors in the
composition, primary colors often produce the best results. Bright colors often become
much lighter, sometimes becoming white, depending on the brightness of colors
beneath.
Pull Force, Pull Direction Specify the strength and direction of a force that pulls the
lightning bolt. Use the Pull Force control with the Stability control to create a Jacob’s
Ladder appearance.
Random Seed Specifies a starting point for randomizing the lightning effects you have
specified. Because random movement of the lightning may interfere with another image
or layer, typing another value for the Random Seed starts the randomizing at a different
