About DMX files

The .dmx file extension primarily refers to the Data Model Exchange format created by Valve Corporation. It is the native source format for the Source 2 engine and Source Filmmaker (SFM), used to store 3D geometry, animation data, and movie session projects. Unlike the older SMD (Source Model Data) format, DMX files are highly flexible and can be encoded in either a human-readable KeyValues2 (XML-like) text format or a compact binary format.

Users frequently encounter friction because .dmx files are strictly proprietary to the Valve ecosystem. Standard 3D software like Blender or Autodesk Maya cannot open them natively without specific plugins (such as Blender Source Tools). Furthermore, binary DMX files appear as unreadable gibberish in text editors, requiring command-line utilities to convert them to ASCII for manual editing. To use these assets in other game engines (like Unity or Unreal Engine) or for general 3D printing/rendering, users must convert them to universally supported formats.

Best Conversion Targets:

For General 3D Editing: Convert to OBJ or FBX. These retain geometry and UVs and are compatible with almost all 3D suites.
For Game Compilation: Convert to SMD if compiling for older Source engine versions, or keep as .DMX for Source 2.
For Archiving/Text Editing: Convert binary DMX to ASCII DMX using Valve's dmxconvert tool to make the data human-readable.

Convert.Guru analyzes your DMX file, detects the exact format, and lets you read the text inside.

Users also converted VMDL, DXF, FBX, DMMX, AUTOSAVE, TMDX, OBJ, ZIP, SMD, VMDL_C, TXT, AVI and PNG files.

FAQ

If you want to convert DMX file to MIDI, SMD, MDL, FBX, MP4, AVI, MOV, WMV, FLV, WEBM, MKV or M4V, you can use Source Filmmaker or similar software from the "Source Engine Data Model" category. In the File menu, look for Save As… or Export….

To convert MTS, MOV, RMVB, DIVX, RM, H264, TS, WMV, VOB, MP4, XVID or AVI files to DMX, try Source Filmmaker or another comparable tool in the "Source Engine Data Model" category.

The DMX Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DMX converter.
