Hopefully BB will read these new comments and reply back.

It doesn't appear that poser atmosphere reacts at all to idl.

So you can either use the envsphere and its light, and not have atmosphere, or you can add additional lights for atmosphere effects.

I would think that atmosphere would react to idl lighting, but I'l be hanged if I can get it to work.

Maybe BB has more voodoo magic up his sleeves for this?

 

Way too many people take way too many things way too seriously.
