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. 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. The system renders diffuse interreflection with infinite bounces and indirect specular reflections in huge, detailed environments, at scales ranging from kilometers to millimeters. Lumen is a fully dynamic global illumination solution that immediately reacts to scene and light changes. Running on PS5 developer hardware, the aptly-named tech demo ‘Lumen in the Land of Nanite’ shows off UE5’s Lumen global illumination system and Nanite micro-geometry system. “One of our goals in this next generation is to achieve photorealism on par with movie CG and real life, and put it within practical reach of development teams of all sizes through highly productive tools and content libraries,” Epic says. While UE 4.25 just launched last week with improvements to its AR and VR support, Epic Games today showed off a tech demo built with new foundational capabilities of Unreal Engine 5 which the company plans to launch in 2021. Unreal Engine is one of the two most popular game engines for creating VR content. With new features for advanced lighting and unprecedented geometric detail, Unreal Engine 5 hopes to enable a generational leap in real-time graphics. Epic Games today revealed a PS5 tech demo built with Unreal Engine 5, the next-gen version of the company’s game engine. ![]()
