During yesterday’s ‘State of Unreal’ keynote at the Game Developers Conference 2019, Epic Games showcased a gorgeous ray tracing demo titled ‘Troll’. Running on a single GeForce RTX 2080Ti graphics card and made with the Unreal Engine 4.22, Troll was developed with no custom plugins or code by Goodbye Kansas and Deep Forest Films.

‘Troll’ was visually inspired by the works of Swedish painter and illustrator John Bauer, who is famous for his illustrations of Swedish folklore and fairy tales anthology ‘Among Gnomes and Trolls’. Epic’s 3Lateral took care of 3D and 4D facial scanning.
