At its annual GDC show, Epic Games showed demos including this short movie, titled Rebirth, that illustrates the photorealistic capabilities of Unreal Engine. It was produced by Quixel, which markets hundreds of 2D and 3D assets (Megascans), some of which were used in the film to create landscapes inspired by Iceland. Epic says that just three artists worked on the short, using an unmodified version of Unreal 4.21.
