Until I bumped into the first video below on YouTube this morning, I had no idea that a lot of The Mandalorian was shot on a virtual set using the Unreal Engine.
Over 50 percent of The Mandalorian Season 1 was filmed using this ground-breaking new methodology, eliminating the need for location shoots entirely. Instead, actors in The Mandalorian performed in an immersive and massive 20’ high by 270-degree semicircular LED video wall and ceiling with a 75’-diameter performance space, where the practical set pieces were combined with digital extensions on the screens. Digital 3D environments created by ILM played back interactively on the LED walls, edited in real-time during the shoot, which allowed for pixel-accurate tracking and perspective-correct 3D imagery rendered at high resolution via systems powered by NVIDIA GPUs. The environments were lit and rendered from the perspective of the camera to provide parallax in real-time, as if the camera were really capturing the physical environment with accurate interactive light on the actors and practical sets, giving showrunner Jon Favreau, executive producer and director Dave Filoni, visual effects supervisor Richard Bluff, and cinematographers Greig Frazier and Barry Baz Idoine, and the episodic directors the ability to make concrete creative choices for visual effects-driven work during photography and achieve real-time in-camera composites on set.
Here is an article about it on the Unreal Engine’s website.
