Ok, Im starting a new map that takes place in space, two ships, but one has a building around it, like its docked...
How would I do this? A space map with two ships with normal land objects put in around it? (and can I add the same cruiser turrets onto the land objects?)
Or a land map with land at its lowest possible points, and two ships (somehow added... Ive never added ships to any level) and the objects (theyre hallways btw) put around it.

EDIT: Now that I think about it, if its a land map, id have to deal with a sky.... so, I guess that means a space map? On the other hand, if i say space, I cant do a conquest sorta map... dang it... land map then. Now I have to make a stary sky... any already made ones in the world files (so i dont have to search through every single one?

Yeah, it is possible to put land items in space and vice versa. You just have to transfer all of the odf/msh/req files from one folder to your own. You could try the Naboo or Coroscant skies. What you're going to have a hard time with though is getting the AI OUT of the ship and into the outside world, and vice versa. AI can't land ships and get out as we can, so you'll prolly either have to build your way out or rely on troop transports.
