Unreal Engine (US, Epic Games) is the industry’s reference AAA engine. Version 5 brought Nanite (virtual geometry with billions of polygons) and Lumen (real-time global illumination), raising the visual bar for games — and beyond: film, automotive, architecture and broadcast.
What it does
- Build AAA and indie games with cutting-edge visuals
- Program logic with Blueprints (visual) or C++
- Use the same engine in virtual film, automotive and architecture
- Tap the Marketplace/Megascans for high-quality assets
Products
The engine is free to download and develop on; the revenue model is a royalty: 5% of gross revenue above US$ 1 million per product (Epic has stated the floor applies to games; official terms govern each case). The ecosystem includes the Unreal Marketplace, Quixel Megascans, Twinmotion and Unreal Editor for Fortnite.
