Dissolve Amount:
Default:
0,
Range:
0 to 1.
The transition ratio between the From and To inputs. A value of 0 gives only the From input and a value of 1 gives only the To input. By default this parameter automatically animates from 0 to 1 to perform a complete transition. The curve controlling this parameter can be adjusted for more detailed control over the timing of the dissolve. In the AVX1 version, Auto Trans must be disabled for this parameter to be used.
-
Dissolve Speed:
Default:
5,
Range:
1 or greater.
The speed of the dissolve between the From and To clips. When set to 1, the dissolve takes place over the entire duration of the effect. When set higher, the dissolve is shorter, although the lightning bolts still change size and brightness over the entire duration. Setting this to 10 can make the transition snappier and more like a flash-frame cut.
-
Max Bolts:
Integer, Default:
35,
Range:
1 to 500.
The maximum number of lightning bolts at the midpoint of the transition.
-
Start:
X & Y, Default:
screen center.
The starting point of the bolts.
-
End:
X & Y, Default:
screen center.
The end point of the bolts.
-
Vary Endpoint:
Default:
1.4,
Range:
any.
Offsets the End location by a random amount within a circle of this radius. If Max Bolts is greater than 1, this can be useful to spread out the different End points.
-
Bolt Width:
Default:
0.11,
Range:
any.
The width of the lightning bolts.
-
Branchiness:
Default:
5,
Range:
0 to 20.
Scales the number of additional bolts that branch from the main bolt. Set this to 0 for basic bolts with no extra branches.
-
Zap Bright:
Default:
1,
Range:
0 or greater.
Scales the brightness of the lightning bolts.
-
Zap Color:
Default rgb:
[1 1 1].
The color of the lightning. If you want to keep the lightning bolt itself bright white, you can still affect the perceived color by adjusting the Glow Color instead.
-
Zap Glow Bright:
Default:
2,
Range:
0 or greater.
Scales the brightness of the glow applied to the lightning.
-
Zap Glow Color:
Default rgb:
[0.5 0.5 1].
The color of the glow applied to the lightning.
-
Zap Glow Width:
Default:
0.224,
Range:
any.
The width of the glow applied to the lightning.
-
Bg Glow Bright:
Default:
8,
Range:
0 or greater.
Scales the brightness of the background glow at the midpoint of the transition.
-
Bg Glow Color:
Default rgb:
[1 1 1].
Scales of the color of the background glow at the midpoint of the transition. The colors and brighness of the glow is also affected by the inputs.
-
Bg Glow Width:
Default:
0.4,
Range:
any.
Scales the background glow distance at the midpoint of the transition. Note that a zero glow width still enhances bright areas; set the brightness parameter to zero if you want no background glow.
-
Start Offset:
Default:
0,
Range:
0 to 1.
The offset from the start point to begin drawing the bolts. This can be useful for animating a lightning strike.
-
Length:
Default:
1,
Range:
0 to 1.
The length of the bolts, beginning at Start Offset. If less than 1, the bolts will not be drawn all the way from start to end. This can be useful for animating a lightning strike.
-
Rand Seed:
Default:
0,
Range:
0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different random lightning bolts, and the same value should give a repeatable result.
-
Affect Alpha:
Default:
0,
Range:
0 or greater.
If this value is positive the output Alpha channel will include some opacity from the lightning and its glow. The maximum of the red, green, and blue brightness is scaled by this value and combined with the background Alpha at each pixel.
