Epic Games has announced Unreal Engine 5, releasing a nine-minute tech demo that showed a character and her dancing light exploring caves and ruins. The real-time demo illustrated the new engine's two core technologies: Nanite and Lumen, which focus on geometry and lighting, respectively. Tony explains how these are used in the video above.What's more, Epic Games confirmed that the demo was running on a PS5. It's meant to show off Unreal Engine 5's tech, and although it's not part of a larger game, it is fully playable. Epic simply used a capture device on a PS5 devkit to get the gorgeous footage.
