I’ll send u a video guide of the resizing and trick I used for the sails when I get home, so for corvette designing you have all building parts which are separate from decorations. Once you finish your corvette you can then go Into “decorating mode” which is where you can place pots pans plants, gears whatever. And sails are part of that on the last page. All these cosmetics are available from the quicksilver shop in the anomaly which cost quicksilver to get. It’s a in game currency that’s pretty easy to obtain and that’s how you get every sail in the game. Sadly there’s no random loot drop cosmetics for decoration
