Unreal Engine 5 announced with PS5 tech demo

Unreal Engine 5 announced with PS5 tech demo

First look at real-time footage on a PlayStation 5 dev kit.

Epic Games has announced Unreal Engine 5, its next generation game engine, with the real-time technical demonstration “Lumen in the Land of Nanite” running live on PlayStation 5.

Speaking to Geoff Keighley in a Summer Game Fest 2020 live stream, Epic Games chief technology officer Kim Libreri said, “It’s a fully playable demo. We plugged a recorder into the back of a PlayStation 5 dev kit and recorded the signal that came out of the HDMI. So it’s a totally live demo, it’s replayable, and it’s a little bit different every time you play it.”

Here is an overview of the demo and engine timeline, via Epic Games:

Lumen in the Land of Nanite

This 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.
Numerous teams and technologies have come together to enable this leap in quality. To build large scenes with Nanite geometry technology, the team made heavy use of the Quixel Megascans library, which provides film-quality objects up to hundreds of millions of polygons. To support vastly larger and more detailed scenes than previous generations, PlayStation 5 provides a dramatic increase in storage bandwidth.

The demo also showcases existing engine systems such as Chaos physics and destruction, Niagara VFX, convolution reverb, and ambisonics rendering.

Unreal Engine 4 and 5 timeline

Unreal Engine 4.25 already supports next-generation console platforms from Sony and Microsoft, and Epic is working closely with console manufacturers and dozens of game developers and publishers using Unreal Engine 4 to build next-gen games.

Unreal Engine 5 will be available in preview in early 2021, and in full release late in 2021, supporting next-generation consoles, current-generation consoles, PC, Mac, iOS, and Android.

We’re designing for forward compatibility, so you can get started with next-gen development now in Unreal Engine 4 and move your projects to Unreal Engine 5 when ready.

We will release Fortnite, built with Unreal Engine 4, on next-gen consoles at launch and, in keeping with our commitment to prove out industry-leading features through internal production, migrate the game to Unreal Engine 5 in mid-2021.
