Description

Amount
Lightning
Sets the proportion of the lightning to be displayed. A value of 0 is no lightning. 100 is the complete lightning bolt. Typical keyframing is 0 at the first keyframe to 100 at the last keyframe.

Anti-alias
Ripple
Sets whether or not transformed areas are smoothed.
  This parameter is not keyframeable.

Birth Rate
Sparkler
Sets the number of sparks generated every frame.

Branch Probability
Lightning
Sets the likelihood that the lightning will have few or many branches. A value of 0 displays no branches. The higher the value, the more branches are likely.

Length
Ripple
Sets the distance between the wave peaks.

Length
Sparkler
Sets the cumulative exposure of the sparks. For example, a value of 3 produces an image that looks as though you left a virtual camera shutter open for the last three frames.

Lifetime
Sparkler
Sets (in frames) how long each spark lives.

Link Speed
Sparkler
If you keyframe the center of the effect, Link Speed causes the movement of the center to be added to the movement of the sparks.

Number of Ripples
Ripple
Sets the number of ripples.

Random Seed
Lightning, Ripple
Sets the base number upon which all random values are calculated. Each value will result in a different random effect.
  This parameter is not keyframeable.

Render Mode Fastámenu

  Standard
  Anti-aliased
Lightning
Sets the quality of the rendered lightning:
  Quick to view just the motion of the lightning.
  Standard to view the full lightning without anti- aliasing while editing the animation.
  Anti-aliased to ensure that fine branches do not break up.

Speed Bias X, SpeedáBias Y
Sparkler
Sets the bias to the direction of the sparks. The system adds these values to the initial random directions.

Strength
Ripple
Sets the height of the waves.

X, Y
Sparkler
Sets the center of the effect. The X and Y values range from –999 to +999, where 0, 0 is the center of the screen.
