I need some guidance.  The scene isn't a a current project but only some experimentation in using GeoControl and developing some terrain materials of my own. 

I threw in some volume clouds and massaged a stock sky.  What I would like to add to this mix is a realistic lightning in the storm cloud (cloud to cloud or cloud to ground).  I tried moving some lights around in the cloud and can't get anything that looks real.

Can it be done in Bryce?
