Choose Layer > Attach Layer > Attach Lightning to active Layer... to attach a new Lightning layer to the active layer.
The new Lightning layer can be selected from the Layers listbox to make it the active layer.
The lightning layer renders flashes of lightning between layers.
Flashes are rendered between 2 layers: the parent and the child layer. The parent layer is the layer the lightning layer is attached to. The child layer can be set with the Target Layer property.
When the Fractal Dimension property is set to 0, straight lines are generated.
When the Target Layer property points to a light layer, flashes are generated between the text and the light.
When the Target Layer property is set to 0, the flashes are launched perpendicular to the layer surface.
If the target layer is the same as the parent layer, flashes are generated between different parts of the same layer.
If the 2nd slider of the Size property is less than 1, the flashes do not reach their target.
The number of flashes that are generated per second. Note that you can use values lower than 1. For example a value of 0.1 means that 1 flash is generated every 10 seconds.
The time a flash is visible in seconds.
The 1st slider controls the thickness of the flash.
The 2nd slider controls the length of the Flash. If the Target Layer property is set to 0 this length is absolute, otherwise it is relative to the distance to the target layer.
The 3th slider controls the detail level of the flash.
The colour of every flash is choosen randomly inbetween the 1st and the 2nd colour.
This determines the shape of the flash: a higher value generates a more freakish shape. A straight line has a fractal dimension of 1, a shape that fills 2D space has a value of 2 and a value of 3 completely fills 3D space.
This determines the amount of branching. A value of 0 never branches.
Flashes are generated between the parent layer (the layer the lightning layer is attached to) and the target layer. Take a look at the Layers listbox to find the index of the target layer.
If the target layer is the same as the parent layer, flashes are generated between different parts of the same layer.
If this property is set to 0, the flashes are launched perpendicular to the layer surface. You can set the length with the 2nd slider of the Flash Size property.
