Hi Thomas,

I know this is kind of an old message, but I'm hoping you are still out
there...

I tried your suggestion with several of the canned examples from the
insert menu and have found an unexpected (by me) result.

On scenes such as Basic_Scene_05: Grass with small clouds in sky, your
settings cause the sky to go from a bright sunny blue sky in the
original scene, to a dark, grey, stormy-looking sky.

I was wondering if you, or anyone else, could explain what is going on.

I'm using POVray 3.7 RC7.

Todd
