What is a USX file?
A USX file is a 3D model file used by Unreal Engine games for creating static meshes in game environments. It contains data that defines the shape and appearance of non-moving objects, such as buildings or terrain, used in a game level. Game designers and developers primarily use USX files to design static structures within the Unreal Engine's development suite.
More Information
USX files are typically found within game assets directories. Designers and developers create USX files with UnrealEd, the Unreal Engine's level editor, where they can adjust a mesh's position, orientation, and size for integration into a game level. Although the model shape in a USX file is static, developers can manipulate it to fit the game's design needs.
NOTE: Since Unreal Engine has evolved over time, newer versions may use different file formats for 3D models, such as .FBX. As a result, USX files may be considered deprecated in more recent development environments.
How to open a USX file
You can open USX files with UnrealEd, the Unreal Engine's level editor. Additionally, you can use Dragon UnPACKer and Unreal Tournament Package Tool to open USX files.
