Unreal Engine is a robust game engine and real-time 3D creation tool. Originally designed for game development, it has since evolved into a comprehensive suite of creation tools that can produce stunning photorealistic visuals for industries like architecture, film, and television. The engine is also used for virtual reality (VR) applications, automotive simulations, and other real-time applications.

Origins of Unreal Engine

Unreal Engine was born out of the vision of Tim Sweeney, the founder of Epic Games. It was initially developed by Epic Games as a game engine for first-person shooter games.

According to Sweeney, the hardest part of the engine to program was the renderer. He had to rewrite its core algorithm several times during development, finding the infrastructure connecting all the subsystems less “glamorous” but equally crucial.

Early Development

In the early stages of development, Sweeney was the driving force behind the engine. Sweeny has stated that he wrote 90 percent of the code in the engine, including the graphics, tools, and networking system.

Evolution of the Engine

Since its inception, the Unreal Engine has undergone several significant evolutions, each time enhancing its capabilities and expanding its application areas. In its current form, the engine is capable of producing stunning visuals that can be used in industries other than gaming.

Uses of Unreal Engine

Unreal Engine’s versatility makes it a popular choice across various industries.


Unreal Engine is a staple in the gaming industry, used to develop visually stunning and immersive games for various platforms.

Film and Animation

In the film and animation industry, Unreal Engine is used to create breathtaking visual effects, virtual production environments, and animated films.

Virtual Reality

Unreal Engine’s powerful VR capabilities allow developers to create immersive virtual reality experiences.

Architecture and Design

Architects and designers use Unreal Engine to create realistic visualizations of their designs.

Automotive Simulations

In the automotive industry, Unreal Engine is used to create detailed and realistic simulations for testing and design purposes.

How Does Unreal Engine Work?

At the heart of Unreal Engine is the Unreal Editor, a user-friendly interface that allows developers to build and edit their projects. The editor provides a range of tools and features that make it easier to create complex and visually stunning scenes.

Benefits of Unreal Engine

Unreal Engine offers several benefits that make it a popular choice among developers.

Advanced Real-Time Visuals

Unreal Engine is renowned for its ability to create advanced real-time visuals. This makes it a popular choice for projects that require high-quality graphics. And this is why it is now an important tool for filmmakers.


While Unreal Engine is completely free to use, if you are a game developer and your game makes over $3,000 per quarter in revenue, you must pay Epic Games a 5% royalty (Fact 3). This makes it a cost-effective choice for many developers.

Easy to Use

Despite its advanced capabilities, Unreal Engine is designed to be user-friendly, making it accessible to developers of all skill levels.

Cross-Platform Development

Unreal Engine supports cross-platform development, allowing developers to create projects that can be deployed on various platforms, including PC, consoles, mobile devices, and VR.

Limitations of Unreal Engine

Despite its many advantages, Unreal Engine does have some limitations.


The very features that make Unreal Engine powerful can also make it complex to use, particularly for beginners. The learning curve can be steep, especially for those new to game development.

Technical Limitations

While Unreal Engine is capable of creating high-quality visuals, this often comes at the cost of performance. Developers may need to optimize their projects to ensure they run smoothly on their target platforms.

Limited Community Support

Although Unreal Engine has a large user base, its community support is not as extensive as some other game engines. This can make finding solutions to specific problems more challenging.

Tips for Getting Started

If you’re interested in using Unreal Engine, here are a few tips to get you started:

  1. Download and Install Unreal Engine from Epic Games.
  2. Take advantage of the wealth of online tutorials and resources available. These can help you understand the basics and get you up and running quickly.
  3. Start with a simple project. This will allow you to learn the ropes without getting overwhelmed.
  4. Don’t be afraid to ask for help. The Unreal Engine community is full of experienced developers who are often willing to lend a hand.


Unreal Engine is a powerful tool that can help you create stunning visuals for a variety of applications. While it does have its limitations, its benefits often outweigh these, making it a popular choice for many developers. Learning Unreal Engine opens up exciting opportunities for immersive experiences for filmmakers.
