What is Unreal Engine?


Unreal Engine is an integrated game development environment (game engine) with a high market share.
This is also a 3D creation tool, and is currently widely used for 3DCG and VR content development in addition to game development.

Overview of Unreal Engine

Unreal Engine was provided by Epic Games, Inc. as an integrated game development environment (game engine).
The game company Epic Games has also developed and sold the game engine “Unreal Engine” necessary for game development.
It’s free and easy to use. For example, it is used in development such as “Fortnite” and “Spellbreak”.
It was initially developed and provided as a game engine, but is currently being widely used as a 3D creation tool for developing 3DCG and VR content in addition to game development.

Features of Unreal Engine

The features of Unity are as follows.

  • Providing a set of functions required for game development
  • Equipped with a real-time engine capable of photorealistic rendering
  • Equipped with “Blueprints Visual Scripting system”
    • It enables no-code programming and game development.
    • In short, it makes game development very easy.
  • Reputation compared to Unity
    • The two major game engines in the world are Unity and Unreal Engine. Both of these are excellent, but the following are the comparative reputations.
      • Unireal Engine has better graphics performance than Unity.
      • Unity can run on a low-spec PC, and its performance is better than Unreal Engine.
    • What is Unity?
  • Multi-platform support
    • It supports multiple platforms.
    • If you develop for one platform, you can release it for other platforms simply by changing the settings.
    • If Unreal Engine supports a new platform, you can release content for that platform simply by updating the engine.
    • Examples of supported platforms are as follows.
      • VR / AR: Ocurus Rift, StreamVR, Playstation VR, Microsoft HoloLens
      • Home video game console: PlayStation4, PlayStation5, Xbox One, Xbox Series X, Nitendo Switch
      • PC platform: Windows, MacOS, Linux
      • Mobile OS: IOS, Android

Unreal Engine Use Cases

The use cases of Unreal Engine other than games are as follows.

  • Architectural design
  • Virtual car showrooms
  • Video production, animation creation
  • Training simulation for the medical industry
  • Training simulation for the aerospace industry

Unreal Engine is now increasingly used in scenes other than game engines, and we believe that it will be a service that will further develop as a 3D creation tool.
