While I love the ability to build and alter my own ships with the mod FCS, the results are, well, blocky. So, I started toying around with some ideas... mostly large, decorative "items/pictures" that could be attached to the outside of the starship.... Chunks of the ship hull , a starfighter, and some static gun turrets so far... Is there much interest in this idea, and what else would you like to see on a starship hull. Radar dishes and antenna arrays come to mind.
I might suggest checking out Mad Tulips mod first. http://community.playstarbound.com/index.php?resources/madtulip-s-spaceship-mod.59/
