# What are the advantages of Unreal Engine?

> Unreal Engine offers top-tier graphics, Nanite and Lumen, visual Blueprint scripting, full source code and free use until a game earns $1 million.

Unreal Engine's main advantages are high-end graphics out of the box, powerful tools for large 3D worlds, visual scripting with Blueprints, access to the full C++ source code and a business model that's free to start. Unreal Engine 5 adds Nanite for very detailed geometry and Lumen for real-time global illumination, which is why many realistic-looking games use it.

## Key advantages

- **Graphics:** physically based rendering, Lumen lighting, Nanite geometry and strong post-processing deliver a realistic look with less manual work.
- **Blueprints:** a node-based visual scripting system that lets designers build gameplay without writing code.
- **Full source code:** studios can modify the engine for their needs.
- **Cross-platform:** PC, PlayStation, Xbox, Nintendo Switch, mobile and VR from one project.
- **Built-in tools:** animation, landscapes, cinematics (Sequencer), audio, physics and MetaHuman for realistic characters.
- **Large ecosystem:** documentation, sample projects, a marketplace and a big community.
- **Beyond games:** used for film and TV virtual production, architecture and simulation.

## Costs

For games, Unreal Engine is free to download and use. Epic charges a royalty, generally 5% of gross revenue after a product earns its first $1 million. Terms for non-game industries differ, so check Epic's current license.

## Drawbacks

- **Steep learning curve,** especially C++ and the engine's architecture.
- **Heavy requirements:** needs a powerful PC to develop and produces large builds.
- **Overkill for small 2D games,** where lighter engines like Godot or Unity are often simpler.
- **Performance pitfalls:** shader-compilation stutter and optimization problems appear if teams don't plan for them.

## FAQ

**What is Unreal Engine best for?**
High-fidelity 3D games such as shooters, action games and open worlds, as well as film and visualization.

**Is Unreal better than Unity?**
Neither is better overall. Unreal leads in high-end 3D graphics and offers source access; Unity is often easier for mobile, 2D and smaller projects and uses C#.

**Does Unreal Engine cost money?**
It's free to start for games. You pay a royalty only once a game's gross revenue passes $1 million.

**Why does Unreal Engine crash so much?**
Crashes usually come from limited RAM or VRAM, outdated GPU drivers, plugins or project errors rather than the engine itself.
