An XAF file works as an XML animation format for tools like 3ds Max or Cal3D, dedicated to motion rather than full character assets, which is why opening it in a text editor displays XML tags full of numeric values for per-bone transforms, timing, and keyframes that don’t animate by themselves, and the file provides animation tracks but does not package geometry, materials, textures, or scene elements, expecting an existing skeleton inside the target application.

An XAF file acts mostly as an animation-only container that doesn’t include characters or environments but instead holds timelines, key poses, and transform tracks that apply rotations—and sometimes positions or scales—to bones identified by names or IDs, often with curve data for blending between frames, whether used for one motion or multiple takes to show how a skeleton evolves over time.
An XAF file generally doesn’t provide everything required to display a finished animation, offering no geometry, materials, textures, lights, or cameras and often not providing a full rig definition, instead assuming you already have the proper skeleton loaded, so by itself it’s just choreography without a performer, and importing it onto mismatched rigs—those with different bone names, structures, orientations, or proportions—can break the animation or distort it with twists and offsets.
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 the file contains “Cal3D” markers or XML attributes that look like Cal3D animation tracks, it’s probably a Cal3D-format XML expecting the correct skeleton/mesh pair, while detailed per-bone transform data and rig-style identifiers are more typical of 3ds Max workflows, and a compact game-oriented clip layout often signals Cal3D, with surrounding files offering hints and the header lines giving the clearest indication of the exporter.
