This mod contains the planet models from the Unstable Space mod, as well as planet textures (including the texture of the planetary rings) from a beta version of the game in .iff format, which, as far as I can tell, are generally slightly higher quality than the versions that shipped with the game.

This mod is untested. Use at your own risk. It should be compatible with all mods that do not change the files in avatars/planets and in images/planets.
