El Ranchito has been one of the VFX companies that has enabled HBO to use virtual production tools in the third season of its science fiction series Westworld. El Ranchito rebuilt Valencia’s City of Arts and Sciences, which HBO used as the setting for the Delos corporation headquarters in San Francisco, using laser scanners and photogrammetry. El Ranchito scanned, modeled and assembled the entire complex designed by Spanish architect Santiago Calatrava in Unreal, to be used in real time. The exterior sequences were shot in the City of Arts and Sciences. However, the interiors, specifically those of Charlotte Hale’s (Tessa Thompson) office, through whose large windows you can see the main artery of the Valencian complex, were affected by the limitations of physical space on the set. Epic Games, Fuse Technical Group, Profile Studios and El Ranchito stepped in to help HBO create the desired ambience on a 50 by 22-foot LED wall on a stage in Los Angeles. Epic worked closely with El Ranchito, who captured the photogrammetry of the City of Arts and Sciences and recreated it as a dynamic scene from Unreal Engine. Fuse Technical Group handled the construction and integration of the LED wall, including scene mapping via Unreal Engine’s nDisplay tool. And Profile Studios streamed the Unreal scene to the LED wall and took care of the camera tracking.
