Just a quick question. What if I wanted to use a shipset that doesn't appear when you are creating a new race and have several shipsets that appear but not that spiffy new set you just downloaded? How do I get that shipset, sans AI, to appear?
Place the ship set in the Pictures\Races folder as normal so that you can use it, and make sure that there are none you don't want to be used as random AI players in the folder.
