Here's a tip to get a background planet which looks as if there's an atmosphere in front of it. I couldn't get this to look right when I was starting with Bryce. All my planets looked like they were IN the atmosphere instead of beyond it. So if your foreground planet is supposed to have an atmosphere, click on the material editor of the planet in the sky, then click on the downward pointing arrow next to the "Material Options" in the top right of the screen and select "Additive". You should now have a realistic renedered planet which looks as if is is "behind" the sky. (You may need to do this to your atmosphere sphere and your underlying sphere)

You can see the effect of using "Additive" on an image like this one.
