What kind of file is a .md3?
Quake III Arena model files use binary meshes, skins, tags, and animation frames. The format is associated with game-era 3D assets and is designed around compact runtime playback rather than general interchange.1
How do I open a .md3?
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 .md3
Poly recognizes the model/x-md3 media type and indexes the filename plus supported model metadata. Valid geometry can receive a visual preview. The Poly agent receives an optimized rendition for compact, information-rich multimodal interaction. The original remains available for download.
Working with .md3 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
