I'm looking to compile a "mod" of sorts for PERSONAL entertainment that will include a few more planets than come with the stock game (of Rebellion with both addons). I presently am bouncing between Maelstrom and Distant Stars - what I'd like to do is export a few planets from each and turn them into their own dedicated mini-mod so I can make maps with a wide variety of planets. Ideally, it'll be compatible with Distant Stars and a mini-mod I've made for myself and was able to drop into Distant Stars.
Anyone have any thoughts? I'm pretty sure it's gonna be more involved than just copying the contents of the galaxyscenariodef (GDF) file's contents from one mod to another's... I've got an idea but really have not much of a clue. I know I'll need to copy entity files and textures, how far off the mark am I?
EDIT: If there is JUST a mod out there that JUST introduces a dozen or two dozen new types of planets, someone please link me!
