The first image shows a scene rendered using Superfly.  The second is the same scene rendered in the background.  There are two lights in the scene: an infinite light that illuminates the outdoor area and a spotlight used to light the stairway inside the door.  It looks as if the background render did not use the infinite light.  The problem doesn't occur with the Firefly renderer, although the figures look a bit odd since I have used Cycles nodes.  

Has anyone else had this problem?  I have lodged a support ticket with Poser.
