Agni's Philosophy. The hairstyles for both Crowe and Lunafreya were first modelled using a real mannequin wig to ensure they could be managed. Their fully rendered wigs were composed of three thousand curves each, a thousand more than originally estimated. The characters' body and facial movements were recorded using motion capture: these included capturing static figures for dialogue segments, and full-body capture for action sequences. The motion actors provided the basis for their characters' appearance: the actors were chosen based on how well they fitted with the staff's vision for the characters. The motion actors' facial expressions were captured using a special head-mounted rig the team had previously developed for the 2012 tech demo. When the character designs were being created, Nozue needed to regularly consult professional hairstylists to ensure that their chosen hairstyles for characters would be feasible in real life. For characters who appeared in the game, the team tried to keep their facial features as close as possible to their in-game counterpart. As with other Japanese CGI films aiming for a realistic tone, the team relied on photogrammetry and an extensive 3D scanning process combined with motion capture. Character clothing was created in a similar way to real-life clothing, with a number of different design variations being tested using paper cutouts. Something that both in-house and external staff contended with was making character movements realistic without being symmetrical; the biggest example was Libertus's need to walk on crutches for much of the film, shifting his weight balance and movement speed. Insomnia—the capital of Lucis—was based in general on international cities, while its core was based on Tokyo: Western elements were added based on fan criticism of Insomnia being too similar to Tokyo during the game's early stages. The design of the Niflheim airships was an updated version of those in the earlier days of Final Fantasy XVs development, when it was known as Versus XIII. Regis was extensively redesigned for the film, which in turn altered his appearance in the game. Initially created with a younger appearance, the team wanted him to have a proper regal air so he would have presence in Kingsglaive, so they aged the character significantly and created a story-based context for the change. The overall theme of the Final Fantasy XV universe was "a fantasy based on reality": to reinforce this, Square Enix collaborated with Audi on a custom version of their
