Thanks for the reply... Yes, I know that you can edit the moon settings in Realistic Sky, but I was wondering if you could actually access and edit the image that they use for the moon - which is not editable in the program itself. Just one of those "Is it possible?" type questions, since I couldn't find a way on my own. As for my scene, I did actually go with a sphere primitive and used the alpha channel in it's shader to fade my planet off into the sky and clouds. Chuck
