how to tell unreal engine version of game

Determining the exact Unreal Engine version used to develop a video game isn't always straightforward. There's no single, universally reliable method. However, several techniques can help you narrow it down, sometimes even pinpointing the specific version. This article explores various approaches, ranging from simple visual clues to more advanced techniques.

Visual Clues and In-Game Assets

Often, the simplest methods provide the most initial information. Start by looking for subtle visual cues within the game itself.

Recognizing Engine-Specific Render Styles

Different Unreal Engine versions have distinct rendering styles. While these are often subtle, experienced gamers or developers might notice variations in lighting, shadows, post-processing effects, or particle systems. For example, the transition from Unreal Engine 4 to Unreal Engine 5 brought significant advancements in lighting and global illumination techniques. Comparing screenshots or videos of games known to use specific Unreal Engine versions can help you identify similarities.

Examining Game Credits or About Sections

Many games list the development tools used in their credits or about sections. Look for mentions of "Unreal Engine," followed by a version number (e.g., "Unreal Engine 4.27," "UE5"). This isn't always present, but it’s the easiest method when available.

Investigating In-Game Menus and Settings

Sometimes, engine information might be subtly embedded within the game's menus or settings screens. Though uncommon, a dedicated developer might include this detail as an Easter egg or for debugging purposes. Thoroughly explore all menus, looking for any hidden information.

Advanced Techniques: Technical Analysis

If visual clues prove insufficient, more advanced techniques are needed. These require more technical expertise and tools.

Examining the Executable File (EXE)

The game's executable file (.exe on Windows) can contain metadata that hints at the engine version. However, this information isn't always easily accessible. You might need specialized tools to extract it, and even then, the information might be obfuscated or incomplete.

Disassembling the Game Code

This is a very advanced method reserved for experienced reverse engineers. Disassembling the game's code will allow inspecting the underlying engine code. Identifying Unreal Engine-specific functions or code signatures can help pinpoint the version. This requires significant technical skill and knowledge of assembly language and the Unreal Engine's internal workings. It’s not a method suitable for casual users.

Checking Online Databases and Forums

Numerous online resources catalogue games and their development tools. Websites and forums dedicated to game development frequently discuss specific games and the engines they're built on. Searching online using the game's title might reveal information about its engine version.

Understanding Limitations

It's crucial to acknowledge the limitations:

Engine Modifications: Developers often heavily modify the Unreal Engine, making it difficult to definitively identify the base version.
Obfuscation: Games might intentionally obscure engine information to prevent reverse engineering.
Lack of Public Information: Not all developers publicly release details about the engine versions they use.

Ultimately, determining the precise Unreal Engine version of a game is often a matter of piecing together clues from various sources. Combining visual observation with online research and – where appropriate – technical analysis will provide the best chance of success.
