“Departure” - Pure
Update: I scorched the earth! It’s based on a NASA photo, with colour remapping on the shader to destroy all greens, plus glowing toxic greens in the ocean, and clouds with some glowing fire clouds, and an atmosphere of pure smog.
I also added a clean blue atmosphere to the ring.
Update 2: I removed the spokes because I like the composition better with a hole there. I added some thrusters, tweaked the lighting so the earth drops more into the background, and added some buildings and roads inside the ring! The terrain & buildings are a displacement shader on the ground, with various voronoi patterns.
