![]() These include Dragon Quest XII, Black Myth: Wukong, Quantum Error, as well as the next games in the Tomb Raider, Kingdom Hearts, and Witcher series. This is done in real time, meaning artists no longer need to wait for light maps to be baked.Ī number of upcoming games are already confirmed to be running on UE5. This isn’t using hardware ray tracing, and yet there’s the scope for infinite light bounces that mean a single light source can flood an area if it’s bright enough. Meanwhile, Lumen is then a dynamic global illumination system that can handle multiple bounces of light through a scene. The tech demo above uses Epic’s Quixel library of megascan objects – their cinematic versions, and not the typical game versions – and then uses Nanite to process that in real time, rendering polygons down to the size of a single pixel, without needing to create normal maps or LODs. Nanite truly takes that to the next level, letting UE5 take a scene comprised of billions of polygons and crunch it down to tens of millions instead. ![]() Nanite can be thought of as a more modern form of bump mapping with normal maps, a process by which you can simulate bumps and wrinkles on the surface of an object, helping to reduce the complexity of the geometry needed to render a cobbled street, for example. ![]() However, Unreal Engine 5 brings two new core technologies: Nanite virtualized micropolygon geometry and Lumen, a fully dynamic global illumination solution.
