Epic Games today unveiled a new first look of Unreal Engine 5 (UE5) with demo running at Sony’s next-gen console PS5. Epic uses “Lumen in the Land of Nanite,” the footage to show what the UE5 is capable of doing. Demo focussed on two core technologies, Nanite and Lumen.
Nanite: It generates “virtualized micro polygon geometry” and allows developers to create “as much geometric detail as the eye can see.” “It means hundreds of millions or billions of polygons can be imported directly into Unreal Engine—anything from ZBrush sculpts to photogrammetry scans to CAD data.”
Lumen: It is a global illumination tool that immediately reacts to scene and light changes. “Artists and designers can create more dynamic scenes using Lumen, for example, changing the sun angle for the time of day, turning on a flashlight, or blowing a hole in the ceiling, and indirect lighting will adapt accordingly.”
Epic says, the team made heavy use of the Quixel Megascans library, which provides film-quality objects up to hundreds of millions of polygons.
Epic says UE5 will be available as a preview in early 2021 and full release by late 2021.
Additionally, Epic also announced it will release Fortnite built on UE4 for PS5 and migrate the Fortnite on UE5 by mid-2021.
