The budget required the reuse of existing sets, but they presented challenges in realizing director Nicholas Meyer's desire for a "livelier" tone. The "Enterprise" was given a ship's bell, boatswain's call, and more blinking lights and signage to match the nautical atmosphere Meyer wanted to convey. Rear-projection systems for bridge displays were replaced with monitors looping taped material created by graphic designer Lee Cole at the Jet Propulsion Laboratory. The bridge set was "unbuttoned" so segments could be removed to better accommodate filming more dynamic action, though Meyer said the 360-degree set was still a challenge to film on. Further complicating the set was that it served three roles: it was not only the "Enterprise" bridge, but also the "Reliant" bridge and Starfleet bridge simulator. The production crew made several "plugs" to cover consoles and alcoves, and pyrotechnics could destroy the plugs during combat sequences without damaging the underlying set. The torpedo bay set is a redress of the Klingon bridge from "The Motion Picture." Kirk's quarters were redressed with more personal items and a more naval appearance, and the same set was used to depict Spock's more monastic quarters."" David Kimble's deck plans from "The Motion Picture" influenced how previously unseen interior arrangements (such as the torpedo bay) were depicted in "The Wrath of Khan".""
