Epic have just revealed a sneak peak of the upcoming Unreal Engine 5 running a demo on the hugely anticipated Playstation 5. Early signs show an impressive photo realism that is going to make Playstation 5 and next gen consoles simply jaw dropping.
Unreal have release a new video that introduces “Lumen in the Land of Nanite” which is a real-time demo that is running LIVE on a Playstation 5.
The demo previews two of the new core technologies that will debut in Unreal Engine 5:
Nanite virtualized micropolygon geometry frees artists to create as much geometric detail as the eye can see. Nanite virtualized geometry means that film-quality source art comprising hundreds of millions or billions of polygons can be imported directly into Unreal Engine—anything from ZBrush sculpts to photogrammetry scans to CAD data—and it just works. Nanite geometry is streamed and scaled in real time so there are no more polygon count budgets, polygon memory budgets, or draw count budgets; there is no need to bake details to normal maps or manually author LODs; and there is no loss in quality.
Lumen is a fully dynamic global illumination solution that immediately reacts to scene and light changes. The system renders diffuse interreflection with infinite bounces and indirect specular reflections in huge, detailed environments, at scales ranging from kilometers to millimeters. Artists and designers can create more dynamic scenes using Lumen, for example, changing the sun angle for time of day, turning on a flashlight, or blowing a hole in the ceiling, and indirect lighting will adapt accordingly. Lumen erases the need to wait for lightmap bakes to finish and to author light map UVs—a huge time savings when an artist can move a light inside the Unreal Editor and lighting looks the same as when the game is run on console.
Epic have to leverage numerous teams and technologies to achieve this kind of leap in quality. To be able to build such large environment the teams made full use of Quixel Megascans, using their massive library of film quality assets. The playstation 5 is also crucial because of its vastly increased storage bandwidth.
