An XAF file is most often an XML animation file used in 3D pipelines—most notably by 3ds Max or Cal3D—and it focuses on motion data only, so although you can view it in a text editor filled with tags and numeric values for keyframes, timing, and per-bone transforms, nothing animates there because it’s pure mathematical description, holding animation tracks but not the mesh, and expecting the target software to already have a matching skeleton.
“Opening” an XAF file typically involves importing it into the correct 3D workflow—such as bringing it into Autodesk 3ds Max through its animation tools or loading it into a Cal3D-compatible pipeline—and mismatches in bone names, hierarchy, or proportions can cause the motion to fail, appear twisted, or shift incorrectly, so checking the file in a text editor for hints like “Cal3D” or references to 3ds Max/Biped/CAT is a quick way to confirm which software should import it and what matching rig you’ll need.
An XAF file is focused on animation data rather than complete character assets, typically holding timelines, keyframes, and tracks that drive bone rotations or other transforms tied to specific bone names or IDs, often with interpolation curves for smooth motion, and depending on the pipeline it may store one animation or many while always defining skeletal movement over time.
An XAF file rarely includes the visual components of animation such as meshes, textures, materials, lights, or cameras, and generally doesn’t offer a standalone skeleton, assuming the correct rig is preloaded, so by itself it acts as choreography without a performer, and importing it into a rig with mismatched naming, hierarchy, orientation, or scale can cause failures, distortions, twisting, or offset motion since the animation tracks can only match what aligns properly.

To determine the XAF’s origin, the fastest move is to inspect it like a clue file by opening it in Notepad or Notepad++ and checking whether it’s readable XML, because structured tags imply an XML animation format while random symbols may be binary, and if readable, scanning the header or using Ctrl+F for Max, Biped, CAT, Autodesk, or familiar bone names can identify a 3ds Max–style animation pipeline.
If “Cal3D” appears explicitly or the XML structure matches Cal3D clip/track formatting, it’s most likely a Cal3D animation file requiring its companion skeleton and mesh, whereas extensive bone-transform lists and rig-specific identifiers fit more with 3ds Max workflows, and runtime-style compact tracks suggest Cal3D, so examining bundled assets and especially the top of the file remains the best way to confirm the intended pipeline.
