Create an advanced lightning effect and then export to transparent PNG sequence

Apr 23, 2013 10:00 AM

Hi,

 

I am new to AE, so please be kind

I need to generate a lightning effect and then export the frames to several PNG images.

 

I figured out how to do the lightning and how to export transparent PNGs, but I can't get rid of the lightning solid background (which is balck in my case).

Do you have any advice?

    When you apply the Advanced Lightning effect to a solid, the effect defaults to compositing the effect over transparency.  You must have other layers in your comp, or you changed the default setting.

     

    Turn off the visibility of the other layers, or do not change the effect's Composite On setting, and you should have transparency.  If you don't, you are making your PNG sequence incorrectly by not including the Alpha Channel.

    Toggle the transparency grid in your comp to make sure that you are creating an alpha channel.

     

    When you render set to the output module to RGB + Alpha and Millions of Colors + and set Color to Straight.
