Applying effects

Last updated 8/12/2010

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 let the lightning stretch 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 clip or layer, typing another value for the Random Seed starts

the randomizing at a different point, changing the movement of the lightning bolt.

Blending Mode Specifies how the lightning is added to the layer.

Simulation Controls the frame-by-frame generation of the lightning. Selecting the Rerun At Each Frame option

regenerates the lightning at each frame. To make the lightning behave the same way at the same frame every time you

run it, do not select this control. Selecting this control may increase rendering time.
