**Thanks, I will have to try that also.  I had no joy using the cloud pic as a background.  It came in waaaaaaay too artifacted.   I love that Carrara will let me choose to create a light that only illuminates the cloud plane.  Here I have done that and adjusted the brightness some.  I need to find my fighter pilot.  He is no doubt loafing in the PX or at the Officers Club.

I want to try out that anything glows for machine gun blast effects.**
