Just as Epic Games officially announced Unreal Engine 5 for the next generation of consoles, a preview video and a set of renderings were released. Epic Games claims that Unreal Engine 5’s goal is to get a photo quality (every time) comparable to movie CG animation in the game( every time, but at the same time, it takes into account the practicality of the development process and provides efficient development tools and content libraries.
The public lying segment of the demo was called “Lumen in the Land of Nanite”, and officials also provided a video of the interpretation of the Chinese subtitles by an official technician.
Demo DEMO DEMO runs on Sony PS5 and will of course support Microsoft’s Xbox Series X, both consoles based on AMD RDNA 2 graphics architecture, which is naturally a great boon for future AMD graphics cards.
In this demonstration, Epic Games unveiled two new technologies for the new engine, a virtual micropolygon geometry that allows developers to create rich geometric details of their eye-opening vision. With it, film and television-grade art, which contains hundreds of millions of polygons, can be imported directly into Unreal Engine.
Nanite geometry can be streamed and scaled in real time, so developers don’t have to tangle the number of polygons, the consumption of polygon memory, and the number of draws, or the need to implement details through normal maps, or manually edit the level of detail. There will be no further loss of picture quality.
To create giant scenes using Nanite geometry technology, the development team made extensive use of the Quixel MegaScans library, which has millions of polygonal movie-grade objects.
The other is Lumen, a fully dynamic global lighting solution that reacts to scene and light changes in real time without the need for dedicated ray-tracing hardware.
It renders indirect specular reflections in large and fine scenes, as well as diffuse reflections that bounce indefinitely, from millimeter to full edge.
Designers can use Lumen to create more dynamic scenes, such as changing the angle of sunlight during the day, turning on the flashlight, or opening a hole in the ceiling, and the system adjusts the indirect lighting to the situation.
In the future, developers will no longer have to wait for lightmap redrawing to be redrawn, no need to edit lightmap Uv, and the lighting effect will be exactly the same as when running the game on the console.
In addition, These Existing Unreal Engine 4 technologies, such as Chaos Physics and Destruction Systems, Niagara VFX, Convolution Reverb, Ambient Stereo Rendering, etc., will be continued.
Unreal Engine 5 will be released in preview slate in early 2021 and official later in 2021, supporting ps5, Xbox Series X, PS4, Xbox One, PC, Mac, iOS, Android and more.
It’s worth noting that the recently released version of Unreal Engine 4.25 already supports Sony PS5 and Microsoft’s Xbox Series X.
Eipc Games is also designing down-compatible features that allow you to develop games first in Unreal Engine 4 and then port it to Unreal Engine 5 in due course.
For example, after the official release of the PS5 and Xbox Series X, Unreal Engine 4’s Fortnite will be launched and upgraded to Unreal Engine 5 in mid-2021.
