Sapphire Plug-ins for Open Fx: UltraZap

S_UltraZap

Generates lightning bolts along a spline and renders them over a background. Increase Vary Endpoint to spread out the ends of the bolts. Adjust the Glow Color for differently colored results. Adjust the Loop Speed parameter to make it traverse the spline over time.

In the Sapphire Render effects submenu.


Inputs:

Background: Optional. The clip to combine the glows with. If no background is given, the Source is also used as the Background.

Mask: Optional. If provided, defines the region where the lightning should be rendered. The glow on the lightning will bleed into areas with no lightning for a natural look.
