Audi R8 model as the royal family's personal transport, and included references to real-world brands and companies such as Japan Airlines. Most of the film's individual props such as the car, Nyx's daggers, the Niflheim mechs and the Ring of the Lucii were created and rendered before main production had begun. Lighting and its effect on characters' skin was of particular importance to the Business Division 2 team, with a lot of work going into making sure shading and transparency fitted with each character's position in a scene in relation to its lighting. Previsualization was initially going to be done entirely in-house, but the team eventually decided to bring in The Third Floor, an external company specializing in previsualization. The Third Floor ended up handling around 40% of the work. The animation was also supposed to be handled in-house using the V-Ray software, but the team found it difficult to adapt the software to their needs. As Nozue wanted to use the experience and technology of Visual Works to create Kingsglaive, they decided to bring in experienced and dedicated outside help to handle V-Ray. This resulted in the cooperation with Digic Pictures, which included former staff from Square Enix's North American branch and were highly skilled in the creation of high-quality cutscenes. For procedural environmental elements such as falling rubble, they used the Houdini animation software. Music The film's score was composed by John R. Graham, with the main theme by Yoko Shimomura, the composer for Final Fantasy XV. The score for Kingsglaive was described by Nozue as "Shimomura meets Hollywood". This effect was reinforced by Graham's work. According to Graham, Nozue wanted a complex musical score. The harmonics and themes change throughout the score to create both an ambiguous atmosphere and a sense of impending tragedy and loss. Graham was brought on board to create a score that would fill the film's world and act as a counterbalance to Shimomura's music from the game, which was incorporated into the overall score. Due to the themes and events of Kingsglaive, Graham needed his music to reflect the weight, contradictions, and shifting "light and dark" perspectives of the characters and locations. To achieve this, he used a combination of live orchestra and electronic elements. He wrote more than 100 minutes of music. Recording was done in Nashville using a symphonic orchestra. The soundtrack was released as a two-disc album on September
