Check out (or revisit) johannes' (cajomi) tutorial on landscapes. He does a good job of explaining how haze works in the realistic sky. Expand your world settings and you will get glorious haze. I think I have some set to 1 inch = 25 miles. The tut also contains a nice description on how the terrain shaders work. Soooo much easier than Bryce. I'm a DTE master for Bryce and Carrara's terrain shaders instantly made sense. Setting the altitude of a texture has always been a tweaker area in Bryce - a lot of trial and error, but it totally makes sense in C, since it's linked to actual units of measure. If you go to the tutorials section of the Eovia site you can find Cajomi's kick ass tutorial. I haven't played with the moon in C. Scott
