Morning Rutra, your right on the close up shots and by the way your renderings are fantastic.  I noticed that in one of them, you actually got the clouds to display a shadow on the water and terrain.  How did you get that.

Question #2, you stated that you used procedural on your rings, how did you design your rings to get that super effect.  Everything about the ring structure looks correct, you nailed the thickness (ring thickness is extremely thin when compared to the planet--just a few kilometers thick at the most).  Is astronomy a hobby or your career--you nailed everything.  Jan
