The entire set of planets and Pluto, along with the major moons around Earth (1, obviously), Mars (2), Jupiter (4), Saturn (7), and Neptune (1 - Triton) - the moons of Uranus aren't included just yet. Charon may or may not be included. Other dwarf planets like Ceres, Vesta, Eris not included just yet.

You only want to copy the contents of Distribution/GameData into your GameData folder - don't copy anything else from Kopernicus or RSS. (RSS-Textures you have to make up manually at the moment).

Do you have ModuleManager 2.6.3 in your GameData folder? Only other folders there for testing should be Kopernicus, RealSolarSystem and RSSTextures. The latter should contain the contents of 2048 (or higher).

I was considering adding some dwarf planets, but I was going for the major bodies first - however, it's more likely that I'd go for Ceres first, due to available images more than anything else.

And to keep you all going whilst you wait:
