.mdl File Extension
File extension details for .mdl
Partial Support| File type | Game model (ambiguous suffix) |
|---|---|
| MIME type | |
| Encoding | Binary model data; structure varies between games and tools |
| Operating systems | Windows, macOS, Linux |
| Opens with | Blender, Noesis |
| Poly support | Partial. The suffix is ambiguous, so accurate format identification is required. |
| Indexed by Poly | Yes. Poly indexes the filename and extracted model metadata when the file is valid. |
| Preview in Poly | Partial. A preview depends on identifying the particular MDL variant. |
| Poly agent | Yes. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files. |
What kind of file is a .mdl?
Game model (ambiguous suffix) files use binary model data; structure varies between games and tools. The suffix is shared by several unrelated game and modelling formats, so the name alone does not identify one specification.1
How do I open a .mdl?
Use Blender or Noesis with a matching importer. Keep skins and related assets alongside the model, then verify scale, axis orientation, materials, and animation timing after import.
Poly support for .mdl
Poly recognizes the model/x-mdl media type and indexes the filename plus supported model metadata. Because MDL is ambiguous, format-aware processing depends on identifying the actual variant. The Poly agent receives an optimized rendition for compact, information-rich multimodal interaction. The original remains available for download.
Working with .mdl files
Export a copy to glTF or GLB for modern scene exchange, or OBJ for a static mesh. Keep the original because game-specific animation, skin, and tag data may not survive conversion.1
