Here's the atmos settings I'm using (using poser units)

I'm going to reset the scene though and try again, because I don't think I'm getting ibl lighting from the envsphere. if I remove all lights, the envspere does not light the scene at all. The rendered scene is supposedly with the envsphere with a image for the light, and one infinite light.

 

 

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