Unreal Engine resource viewer (formerly Unreal Model Viewer) is a program for viewing and extracting resources from various games made with Unreal Engine. Sometimes the program is referenced as "umodel", the short of "unreal" and "model viewer".

Feature Highlights

Loading packages from more than 300 games based on all Unreal engine generations

Visualization of skeletal meshes with animations

Visualization of internal skeletal mesh information like skeleton hierarchy and binding vertices to the skeleton bones

Visualizarion of vertex meshes

Visualization of static meshes

Viewing supported material types and their internal structure

Export of skeletal, vertex and static meshes and animations into formats supported by 3d modeling software and by Unreal engine

Export textures into tga or dds format

Export sounds, ScaleForm and FaceFX

System Requirements

Windows OS or Linux

CPU with SSE2 support

SDL 2.0 (included into package for Windows)

OpenGL 1.1 videocard (OpenGL 2.0 is recommended)

Command Line

ATTENTION! This site has a few tutorial videos and FAQ. It would be useful (especially for beginners) to watch them before starting to use UE Viewer. The links are available at the top of this page. Below UE Viewer is referenced as "umodel" for simplicity (it's executable file name).

Command line format:

umodel [options] package-name [object-name]

Major options:





viewer options -meshes exclude non-mesh objects from browsing in viewer mode exporter options -export start umodel in exporter mode -out=path set directory for exported files -dds export DXT textures in DDS format -uncook UE3: umodel would export files to the directories corresponding to their package names where objects were placed by designer before cooking -groups do not use object type (SkeletalMesh, Texture2D etc) for export directory name but use object's group name instead -sounds allow sound export -3rdparty allow ScaleForm and FaceFX export common options -path=path set path to the game files; you should enclose path into double quotes when it has spaces inside -noanim/-nomesh/-nostat/-notex disable loading of animation/SkeletalMesh/StaticMesh/textures (could be necessary because of umodel incompatibility with particular game) -game=game tells to umodel that opening file belongs to the particular game; it could be required when umodel is not able to detect game by itself; to get list of available game tags launch umodel with -taglist option -pkg=package load additional package (you may specify any number of -pkg=... options) -ios/-ps3 tells to umodel that you are opening file which was cooked for iOS or PS3 platform (all other platforms are detected automatically)

For full option list launch umodel without arguments.

All options are order-independent. Package name is a full or short name of package. Using short name usually requires -path=... option. Check examples below for explaination.

Command line examples:

umodel -path=c:/games/ut2004 HumanMaleA

display all packaged objects from HumanMaleA

umodel -path=c:/games/ut2004 -meshes HumanMaleA

display all meshes from HumanMaleA

umodel -path=c:/games/ut2004 HumanMaleA MercMaleD

display mesh MercMaleD from package HumanMaleA

umodel -path=c:/games/ut2004 -export HumanMaleA MercMaleD

export SkeletalMesh MercMaleD from HumanMaleA package

umodel -path=c:/games/ut2004 -export HumanMaleA MercMaleD

export SkeletalMesh MercMaleD and all used resources (animation, textures etc)

umodel -path=c:/games/ut2004 -export HumanMaleA BipedMaleA

export animations (MeshAnimation) BipedMaleA from HumanMaleA package

umodel -path=c:/games/ut2004 -export HumanMaleA

export all supported objects from HumanMaleA package

umodel -path=c:/games/ut2004 -export *.ukx

export everything from all ukx files

umodel -path=c:/games/ut2004 -list HumanMaleA

list contents of HumanMaleA package (object and class names)

umodel -list c:/games/unreal/music/QueenSong.umx

list contents of QueenSong.umx package from Unreal1. Here is package name specified with full file path.

User Interface

Program controlled mostly with keyboard. To get key assignment help, press <H> (help) key. Main keys:

ESC exit from program H get key help information PgUp, PgDown switching between loaded objects [, ] switch between mesh animations <, > rewind animation time backward/forward Space, X start animation playback (single and looped) Ctrl+A switch between different animation sets (required for viewing UE3 animations) Ctrl+T tag/untag mesh for multipart mesh rendering F focus camera on mesh Ctrl+X export current displaying object Ctrl+S/Alt+S take a screenshot; when Alt+S is used backgound will be made transparent Ctrl+Q toggle displaying of texts and coordinate system axis

You can rotate camera holding left mouse button, zoom with right mouse button, or pan camera (move alongside screen plane) with middle mouse button.

There is a nice demonstration of viewer capabilities and program control in tutorial videos.
