Thanks everyone. I think I want to little more basic with that ceiling texture. I can't get a good falloff from glow to stone in some areas, and boy that bothers me lol
But I kinda want to do a biome simulation. I like where the second image is going. Maybe a couple more layers of soft clouds with a circular break in the center where there is more burn off and ambient hear, maybe some rain cloud aim on. The lower cloud layers.
I wanted to do vegetation but I honestly got nothing that really feels right. So maybe some different grass mixes.
I don't really have the motivation right now as I'm actually trying to fight with TreeIt to get some basic alien looking trees for the derelict scene.
