cairyn gave me some advice on the renders, and that got rid of the problem I had with Cycles renders in Blender. For a Film that was completed in 2017, I generated a planet in 3ds Max, using 8K maps. So this year I tried to use the same maps and methodology, however Blender does things differently, and I have not yet found a way to mix materials using light and shadow, like you could in 3dsMax. But the render looks great, as it is. Say Hello to the Planet Earth. At some point I will have to make exterior shots with mountains and buildings, soon. We'll see.
