I'm trying to export a sky, to use on a Poser Sky dome.

Hear are two images.  The top image is what I see in my Vue render window, and the bottom image is what I get when I export that same scene.

There are a couple things I do'nt understand about these two renders.

First is why the Sun Light(the big star from the upper right hand corner of the first above image) does'nt appear anywhere on the exported sky?  I understand why the bottom of the export is white, because an infinite plane was there; but I thought the Sun would shine through...:ohmy:

And second is where that yellow smudge comes from, in the lower left hand corner of the above image?  I think it is a lens flare; but I did'nt see any Sky Editor, or Render Options, to change this to white with?
