About Unreal Engine

Unreal Engine is a professional-grade, free-to-use game development engine by Epic Games, available on Windows, Mac, and Linux, used in AAA games, architectural visualisation, film production, and live events. Its Nanite virtualised geometry system renders film-quality meshes without manual LOD work, and Lumen provides fully dynamic global illumination. Blueprint visual scripting allows logic to be built without C++ knowledge, though C++ is supported for performance-critical systems. A 5% gross royalty applies only to commercial products that earn over $1 million in lifetime revenue. Unreal Engine powers titles like Fortnite, Final Fantasy VII Remake, and The Matrix Awakens tech demo, demonstrating the ceiling of what is achievable.
