I have been playing around with creating a planet recently, and after seeing the results in-game, I should have done this months ago. This is completely temporary and is very likely to change, but I needed to take some screenshots and share:

Main menu with ice planet

Multiplayer menu with ice planet

In-game with ice planet

Right now, the planet is stationary, but I hope to make it move around with the camera a little bit. I made the planet from scratch using a photograph and a powerful image editor, nice eh?
