Atomic Systems

Hi folk,
I recently downloaded the Kosmos environment utility with the 1.1 upgrade, and it is very impressive but, I downloaded the two available "thunder" environments and was disappointed when I ran them that no lightning was visible, except in one instance there was very faint scratchy lines dashing about all over the sky very quickly. Is this because a seperate plug-in is needed?
One environment was JBstormyweatherWithMSThunder1 and the other was Abula21SpringRainWithMOThunder2.
Any ideas please? Do I need to disable Sky!Conductor2 ?

All the sky conductor enviroments are available for Kosmos so can remove sky conductor without losing anything.

I found the lightning very good. In fact its so good that it gets annoying.

Cheers Ian
