The Mandalorian’s set used some serious Danger Room/Holodeck stuff to pull off a virtual shot-on-location feel for its many different settings, and powering the world projected on its giant LED wall was none other than Epic Games’ Unreal Engine 4.
The setup allowed the cast to shoot in multiple locations in a single day, to shoot at a particular time of day for 10 hours if necessary, or even (literally) move a mountain in the background to get a better shot. But you really see (or, rather, don’t see) the difference when characters are aboard a moving vehicle.
Wow. I was totally unaware of this and never noticed a lot of things were shots like this while watching it.
