Random Terrain

Found at random on a space station a month or two ago. My other two exotics were also random finds - one landed inside my freighter, and the other (a tiger-striped “squid ship”) I found on a trade platform last night, again at random.

Is every Exotic unique (or supposed to be)?

according to what i've read, there's a finite number of Exotic ships but should at least be unique color scheme and animations...
