Unreal Engine FAQ
Is Unreal Engine really free?
Yes. Unreal Engine is free to download and use. You only pay a 5% royalty on gross revenue after your product earns more than $1,000,000. Revenue earned through the Epic Games Store is exempt from the royalty.
What is the difference between Unreal Engine and Unity?
Unreal Engine excels at high-fidelity 3D graphics and is preferred for AAA games and photorealistic projects. Unity is lighter-weight, has a gentler learning curve, and dominates mobile and indie game development. Unreal uses C++ and Blueprints; Unity uses C#.
Can I use Unreal Engine for non-game projects?
Yes. Unreal Engine is widely used for architectural visualization, automotive design, film and TV production (virtual production), training simulations, and AR/VR experiences. No royalty applies to non-game linear content like films.
Do I need to know C++ to use Unreal Engine?
No. Unreal Engine''s Blueprint visual scripting system lets you build complete games without writing code. However, C++ knowledge is needed for engine-level customization and performance-critical systems.
What are the system requirements for Unreal Engine 5?
Epic recommends a modern multi-core CPU, 32 GB RAM, an NVIDIA RTX 2080 or AMD RX 6800 XT GPU, and an SSD with at least 100 GB free space. Nanite and Lumen features benefit significantly from newer GPU hardware.
