These planets can contain lava based life. the surface will then look red, when it dont has life, it will then look brwon or black. They have an atmosphere and clouds.
It would be pretty amazing to see lava seas on planets very close to their sun. Maybe Io would need to be reclassed as one of them, like Titan was when titans were added as a class.
What I did requires cache editing and many shaders are different per each person's computer. I haven't even got it to work on my own with recent changes.
