What is an MDX file?
An MDX file is a model file used in Blizzard Entertainment’s game “Warcraft 3.” These files contain 3D models, including meshes, textures, animations, and other data necessary for rendering characters, buildings, and other objects within the game. Here’s a detailed breakdown of the MDX file format in the context of Warcraft 3:
Structure of an MDX File
Header
The header typically contains metadata about the model, such as the version of the file format and other general information.
Vertices
This section contains the 3D coordinates of the model’s vertices. Vertices are the points in 3D space that make up the model’s mesh.
Normals
Normals are vectors that are perpendicular to the surface of the model at each vertex. They are used for lighting calculations.
Texture Coordinates
These coordinates map the 2D textures onto the 3D model.
Faces
Faces (or polygons) define how vertices are connected to form the 3D shape. Typically, models are made up of triangles or quads.
Bones
Bones are used for skeletal animation, allowing the model to move in a lifelike manner.
Animations
This section includes the data for animating the model, such as keyframes and bone transformations.
Materials
Materials define the appearance of the model’s surface, including textures, colors, and shading properties.
Geosets
Geosets are collections of vertices, normals, and faces that make up parts of the model. Each geoset can have its own material.
Attachments
These are points on the model where other objects can be attached, like weapons or effects.
Events
Events can trigger specific actions or effects during the model’s animation, like sound effects or particle emissions.
Tools for Editing MDX Files
- Warcraft 3 Model Editor: Tools like the Warcraft 3 Model Editor (also known as War3ModelEditor) allow you to view and edit MDX files.
- MDLX Converter: This tool converts MDX files to and from the MDL format, which is a human-readable text format.
MDX vs. MDL
- MDX: Binary format, more compact and efficient for the game engine to read.
- MDL: Text format, easier for humans to read and edit.
Converting MDX to MDL
- Open the MDLX Converter.
- Load your MDX file into the converter.
- Convert the file to MDL format for easier editing.
- Edit the MDL file using a text editor.
- Convert the file back to MDX using the converter.
Example Use Case
If you want to customize a character model in Warcraft 3, you would:
- Extract the MDX file from the game files.
- Convert it to MDL for easier editing.
- Make the necessary changes to the model, such as modifying vertices, textures, or animations.
- Convert the edited MDL file back to MDX.
- Import the modified MDX file back into the game.
How to open an MDX file
Opening an MDX file, especially for a game like Warcraft 3, usually involves using specific tools designed for working with game models. You can open and edit an MDX file with following tools.
- Warcraft 3 Model Editor (War3ModelEditor)
- MDLX Converter
- Blender (with MDX Import/Export plugin)
- Notepad++ (or any text editor, if converting to MDL)
Key Characteristics of MDX Files
| Characteristic | Description |
|---|---|
| File Extension | .mdx |
| Primary Variants | Blizzard 3D Model, MDict Dictionary, Daemon Tools Disc Image, Ansys Data, X68000 Audio |
| Primary Use | Varies by variant: 3D game assets, dictionary databases, virtual disc images, simulation data |
| Format Type | Mixed: Binary (game models, disc images), Structured binary (dictionaries), ASCII (engineering data) |
| Main Feature | Format polymorphism—single extension serving multiple completely different purposes |
| Compatibility | Highly dependent on variant; requires specific dedicated software for each type |
| Security Profile | Moderate; disc images and dictionaries are generally safe; game models may contain custom code |
FAQ
Q1: Can I open an MDX file with a text editor?
A: It depends on the variant. MDict dictionary files show XML metadata at the beginning, and Ansys files are entirely text-based. However, Blizzard 3D models and Daemon Tools disc images are binary and will appear as gibberish in text editors.
Q2: What software do I need to view Warcraft III MDX models?
A: Use War3ModelEditor or MDLX Converter to view and edit Blizzard MDX model files. These tools can also convert between MDX and the editable MDL text format.
Q3: Can I use MDict dictionary files on macOS?
A: macOS native Dictionary app does not support MDX directly, but you can use GoldenDict-ng (which supports MDX) or convert MDX files to Apple’s dictionary format using the PyGlossary tool.
Q4: How do I mount an MDX disc image?
A: Download Daemon Tools Lite (free version available), install it, then right-click the MDX file and select “Mount” or use the Daemon Tools interface to mount the image as a virtual drive.
Q5: Are MDX and MDL the same thing?
A: No—they are related formats for Blizzard 3D models. MDX is the binary format used in final games, while MDL is the human-readable text format used for editing and development. Converters exist to translate between them.
