Terrain Toolkit

I was curious if there were any way to use more than 6 textures to color the map with, I am recreating the surface of the moon, or at least a portion, and I want to have very small changes in color over small distances, not just 6, more around 10 or 11.

You could use one of those 6 textures to be very "stretched out", and provide this 'detailed' coloring over different parts of the moon. you can then use the other five for, rock, hard rock, darkish rock, and maybe some water? :)
