Hybride's team of VFX specialists, working under the supervision of the film's visual effects supervisors Volker Engel and Marc Weigert, was mandated to create full high-resolution CG shots for a scene featuring US Black Hawk helicopters heading towards the White House. The studio's main challenge was recreating a vibrant, realistic virtual city environment down to the smallest detail. The complexity of shots allowed Hybride to raise the bar on its technical expertise, taking teams of experienced VFX artists to new levels of creativity.
Several innovative techniques developed for the project enabled Hybride's artists and programmers to produce extremely complex scenes. The team developed innovative tools that facilitated the creation of an entirely virtual city-traffic lights, street lamps, bicycle racks, road signage and advertising panels were automatically generated to maximize production time. Hybride artists also developed special tools to create and populate scene elements including vegetation and vehicles, as well as a cutting-edge tool to populate trees and simulate their movement.
Due to the high level of shot complexity, Hybride artists used deep image compositing techniques to manage the sequence and maintain quality without compromising the level of detail desired.
"This new procedure helped us overcome machine limitations experienced in the past, allowing us to incorporate an unlimited number of elements," said Pierre Raymond, Hybride President. "We're extremely proud of our work and the results of our research will enable Hybride to take on increasingly complex projects, laying the foundation for a very promising future."
