What UE Viewer is

UE Viewer is a free, open source program for viewing and extracting resources from Unreal Engine games. It loads packages from more than 300 games across Unreal Engine generations and focuses on Unreal Engine titles rather than games made with other engines. The program displays skeletal, vertex, and static meshes, including skeleton hierarchies and vertex-to-bone bindings for skeletal meshes. Supported materials can be inspected, while some material types are unsupported. Meshes and animations can be exported to formats used by 3D modeling software and Unreal Engine; textures can be exported as TGA or DDS, along with sounds, ScaleForm, and FaceFX. Command-line viewing and exporting are supported. Windows and Linux downloads are listed, while macOS support is described as a command-line exporter without visualization or multithreading. Linux has no graphical interface. Additive animations do not work.
