Bolt Structure
Bolts
The number of lightning bolts to draw between the Start and End location.
Bolt Width
The width of the lightning bolts.
Bolt Length
The length of the lightning bolts. If less than 1, the bolts will not be drawn all the way from start to end.
Wrinkle Amp
Scales the amount of wrinkles in the bolts. Decrease for straighter, smoother bolts or increase for more kinky bolts.
Curve Amp
Similar to Wrinkle Amp but affects the general path of the bolt. If decreased, the bolt will stay closer to the line between the Start and End points. If increased, it can wander further away from this line. This differs from the Wrinkle Amp parameter in that it can be used to make straighter bolts while still keeping the wrinkles at the detailed level.
Taper Start
Determines how pointed the start of the bolts are. If 0, the entire bolt will have equal width. If 1, the bolts will thin out along their entire length for a pointed end. If it is .5, the bolts will start thin and grow to the width parameter at the center of the bolt.
Taper End
Determines how pointed the end of the bolts are. If 0, the entire bolt will have equal width. If 1, the bolts will thin out along their entire length for a pointed end. If it is .5, the bolts will start thinning out halfway between the start and end points.
Feather Bolt
Add softness to the bolt before glowing.
Zap Edge Blur
Only blur the edges of the zap. This is useful if there is noise on the zap.
Zap Brightness
Scales the brightness of the lightning bolts.
Start Color
The color at the start of the main bolt.
End Color
The color at the tip of the main bolt.
Vary Bolt Hue
This varies the start and end color between multiple bolts. This does not change the color along a single bolt.
Vary Width
The amount of random variation in the width of the bolts along their lengths.
Vary Endpoint
Offsets the End location by a random amount within a circle of this radius. If Bolts is greater than 1, this can be useful to spread out the different End points. For example, you can create multiple radiating bolts by increasing this radius and placing the End point near the Start point.
Random Seed
Used to initialize the random number generator. The actual seed value is not significant, but different seeds produce different random lightning bolts and the same value should give a repeatable result.
Bolt Animation
Start Offset
The offset from the start point of where bolts are drawn.
Bolt Noise
Applies a noise pattern to the bolt before the glow.
Bolt Noise Freq
The frequency of the bolt noise.
Bolt Branchiness
Branches Only
Hides the core bolt and only shows the branches.
Branchiness
Scales the number of additional bolts that branch from the main bolt. Set this to 0 for basic bolts with no extra branches.
Branch Angle
The maximum angle of the random branches relative to the bolt they are branching off of. If this is 0, the branches will be more lined up with the main bolt. With larger values, the branches will be more perpendicular to the main bolt.
Branch Length
The scaled length of the branches relative to the distance between the Start and End points.
Branch Color
The color at the tips of the branches.
Vary Branch Hue
Varies the end color between multiple branches.
Branch Style
Specifies how the branch width should be calculated.
Width Uses Dist
Branch width is calculated based on how far along the bolt the branch splits off.
Width Uses Bolt Width
Branch width is calculated based on how wide the bolt is at the point where the branch splits off.
Branch Width
Width of branches relative to the main bolt.
Secondary Bolt Structure
Secondary Bolts
The number of lightning bolts to draw between the Start and End location.
Secondary Bolt Width
The width of the lightning bolts.
Secondary Length

Controls the spatial frequency of the atmospheric noise. Turn this up to get finer details or turn down for broader overall variation.
Composite
Combine

Add
Adds the lightning to the image. This gives brighter glows over light backgrounds.

Scales the brightness of the image before combining with the lightning. If 0, the result will contain only the lightning over black.
