Ok I was wondering, I own Celestia( free planetarium software) and It is heavily modded at the moment with tons of planet,asteroid and star textures,(not to mention nebulae, black holes ,and comets)I noticed that the planets in galactic civilizations are basically the same kind of models and textures. is it possible for me to swap or just add some more planet textures to the game with my existing ones from celestia. if so do i need to resize them to a certain size and where would i locate the files i need to modify .or folders i need to add to also do i need bumpmaps or just textures?
if this is possible would i be able to also add black hole textures to anomolies and asteroids also?
