"Sony is pioneering here with the PlayStation 5 architecture. Not just a little bit faster but a lot faster, so that you can bring in this geometry and display it, despite it not all fitting and memory, you know, taking advantage of next generation SSD architectures and everything else," Epic Games CEO Tim Sweeney told Eurogamer's Digital Foundry. "One of the big efforts that's been done and is ongoing in Unreal Engine 5 now is optimising for next generation storage to make loading faster by multiples of current performance. The storage architecture for both prioritizes bandwidth over pure size, allowing developers to transfer game assets much faster than previous generations while lessening the need for load times. Nanite's description mentions asset streaming, which is likely related to the proprietary solid-state drives (SSDs) on the PlayStation 5 and Xbox Series X. Nanite and Lumen seem to be related to key features of both next-gen consoles.

Those new additions come part and parcel with existing Unreal Engine 4 features like Chaos physics and Niagara VFX. The second feature is Lumen, a global illumination system that allows game artists to create more dynamic and realistic lighting. It allows for real-time changes in level of detail without any visible pop-in.

(Capcom's Resident Evil team squeals with delight.) Geometry imported through Nanite is streamed, drawn, and scaled into the game in real-time. The first is Nanite, a feature that allows developers to directly import film-quality models and art into Unreal Engine 5, whether that's sculpts from Zbrush, CAD data, or photogrammetry scans. The real-time demo takes its name from two of those core technologies. The demo illustrates some of the new technologies in Unreal Engine 5, but also the power of Sony's upcoming console.

The engine developer showed off "Lumen in the Land of Nanite", a live demo reportedly running on PlayStation 5 hardware. Today, Epic Games gave everyone their first look at the next iteration of the Unreal Engine, and the next PlayStation to boot.
