Unity vs Unreal 2025: Which Engine is Better for Which Project?
READ MORE READ MORE
Epic Games revolutionized the world of game development with Unreal Engine 5. However, with the release of Unreal Engine 5.4 in 2025, this revolution has advanced even further. New features have not only made development processes more efficient but have also significantly improved visual quality and performance.
Nanite technology was a groundbreaking development that made it possible to process highly detailed geometries in real-time. With the 5.4 update, Nanite has become even more flexible. Now, direct deformations (such as soft body physics) can be applied to Nanite-supported assets. This is a major step for organic structures and dynamic scene changes. Especially in large open-world projects, it is now much easier to offer massive detail without compromising performance.
Lumen is a real-time global lighting and reflection system. With Unreal Engine 5.4, Lumen now works even more efficiently in enclosed spaces, smaller scenes, and on lower-end hardware. The latest updates have significantly improved how light spreads across surfaces and the naturalness of reflections. As a result, creating cinematic-quality scenes no longer requires heavy baking processes.
Unreal Engine 5.4 has also introduced revolutionary innovations in character animation. The Control Rig system now allows for more complex animations to be created with less code. Additionally, new Procedural Animation Tools enable systems that automatically generate animations based on dynamic environmental responses. For instance, a character can now automatically adapt to sloped terrain while walking, and their hands can interact realistically with nearby objects.
With the MetaSounds system, sound design has entered a completely new dimension. The updates in 5.4 allow sounds to be controlled via a fully node-based system, offering limitless creative possibilities in both music and sound effect design. For developers wanting to create interactive sound experiences, MetaSounds has become an indispensable tool.
Unreal Engine 5.4 offers a more seamless development experience across consoles, mobile devices, and PCs. Epic Games has developed mobile-optimized shaders and special LOD (Level of Detail) systems for low-powered devices. As a result, large projects now perform better on both high-end devices and lower-spec hardware.
Unreal Engine 5.4 not only makes the game development process easier but also gives developers the power to create worlds beyond their imagination. The balance between realism, performance, and creativity has reached new heights with this release. 2025 and beyond look set to be the year of major projects and creative experiences within the Unreal Engine ecosystem.
