All Gaea output, including the color shading
What was strange, I found, was that in order to get it to render properly, I had to dump all the Satmap images (one of the Gaea outputs) into a multi-merged Colour Function in one surface shader.
If I tried to have the individual color maps as color functions on individual shaders, only one would be seen.
Nevertheless, the results aren't bad, but not all the way there yet.
