Use these options to set the behavior and appearance of your lightning effect.
When Group Lightning is turned on, Maya creates a group node and places the newly created lightning into it. No special controls are associated with this group. However, grouping can help you organize your lightning effects.
Specifies how you want the lightning created. Click to turn on one of the following options:
Creates lightning between all the selected objects.
Creates lightning from the first selected object to the other selected objects in the order of their selection.
Creates lightning from the first object you select to all the other selected objects.
Notice in the illustration for the In Order option above, the lightning does not extend from object 4 back to object 1. If you want to do this, you need to add another lightning effect between objects 4 and 1.
Lightning is made up of soft body curves with extruded surfaces. The Curve Segments value sets the number of segments in the lightning.
