So I put an engine on my ship, and I get the prompt on the helm control that shows I can switch to the engine by pressing RMB, but RMB is also used to release control so I can't actually switch it seems. I also tried using the RMB directly on the engine but nothing happens. From what I could find online you just have to build the engine on the ship and you should be good to go, but I can't seem to switch to it no matter what I do. Any ideas?
