Unreal Engine 5

Technology

A real-time 3D creation tool from Epic Games. It's used as a benchmark to illustrate the difference between traditional, deterministic 3D rendering and Sora's novel approach, which appears to generate physically consistent scenes without explicit object modeling.

Summary

Unreal Engine 5 (UE5) is a sophisticated 3D creation tool developed by Epic Games, known for its advanced real-time rendering capabilities. It introduced revolutionary technologies such as Nanite for virtualized geometry and Lumen for dynamic global illumination, enabling developers to create highly detailed and realistic environments. In contemporary tech discourse, UE5 is often contrasted with generative AI models like OpenAI's Sora, which generates video from text. While UE5 represents the pinnacle of traditional 3D modeling and physics-based rendering, Sora's ability to simulate physics through data-driven learning suggests a shift in how virtual worlds might be constructed, potentially bypassing the "uncanny valley" that traditional animation has long struggled to cross.

    Unreal Engine 5 (UE5) is the latest iteration of Unreal Engine, developed by Epic Games. It was revealed in May 2020 and officially released in April 2022. Unreal Engine 5 includes multiple upgrades and new features, including Nanite, a system that automatically adjusts the level of detail "Level of detail (computer graphics)") of meshes, and Lumen, a dynamic global illumination and reflections "Reflection (computer graphics)") system that leverages software as well as hardware accelerated ray [...] A major feature of Unreal Engine 5 is Nanite, a virtualized geometry system that allows developers to use photogrammetry and other high-detail meshes in their games without significant performance impact. Traditionally, artists had to create multiple models for different levels of detail (LoDs) and generate normal maps for finer details. Nanite automatically manages LoDs by scaling models dynamically based on draw distance, screen resolution, and performance requirements. It utilizes a [...] Unreal Engine 5 has been credited with allowing developers to create games using higher fidelity assets via Nanite with more realistic lighting via Lumen. Gaming outlets credited UE5 for its use in multiple games from 2023 to 2025 including Black Myth: Wukong, Remnant 2, Senua's Saga: Hellblade II and Avowed. It has also been praised for allowing smaller independent and AA developers to achieve similar levels of graphical fidelity as larger studios. For example, Sandfall Interactive's debut

  • Why do video games in 2026 still not look as good as this old PS5 ...

    Since then, Unreal Engine 5 has unsurprisingly claimed a place in our pick of the best game development software. It's also now the biggest engine in terms of game sales (although Unity remains the most-used engine overall). But that May 2020 demo has resurfaced, and some people are wondering, why do games in 2026 still not look like that? [...] Over five years ago, Epic Games dropped the Lumen in the Land of Nanite tech demo running on PlayStation 5 to unveil the power of Unreal Engine 5. The demo showcased the breakthrough features of Nanite's virtualized micropolygon geometry for extreme detail and Lumen for fully dynamic global illumination. [...] Epic's original PS5 Unreal Engine 5 tech demo represented something of a milestone for next-gen gaming. It highlighted the PS5's storage bandwidth and the ability to achieve unprecedented realism and massive environments without traditional loading screens or lightmaps. Whether games have yet achieved the visuals it promised can be debated, and that's just what's happening after someone asked on X “why haven't games come close to this yet?”
