An XAF file serves mainly as an XML-based animation container in 3D workflows, such as those in 3ds Max or Cal3D, storing movement information instead of full character assets, so opening it in a text editor reveals structured XML with numbers describing timing, keyframes, and bone transforms that don’t “play,” and the file contains only animation tracks while excluding meshes, textures, materials, and other scene data, requiring a compatible rig to interpret it.
“Opening” an XAF file most often requires 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 lets you determine which software should import it and what matching rig you’ll need.
An XAF file is essentially 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 rarely contains the visual elements of an animation like meshes, textures, materials, or scene components, and often lacks a full independent skeleton definition, assuming the correct rig already exists, which is why the file alone feels more like movement instructions than a complete performance, and why incorrect rig matches—due to different naming, hierarchy, orientation, or proportions—lead to broken or distorted results.

To determine which type of XAF you’re dealing with, the fastest method is to treat it like a self-describing text file, using Notepad or ideally Notepad++ to see if it’s readable XML—structured tags mean XML, while scrambled symbols could imply a binary or misleading extension—and if it is readable, use Ctrl+F or skim the first 20–50 lines for terms like Max, Biped, CAT, or Autodesk plus recognizable bone names that indicate a 3ds Max animation workflow.
If the file openly references “Cal3D” or uses XML tags that follow Cal3D animation conventions, it’s likely a Cal3D XML needing its corresponding skeleton and mesh, whereas dense bone-transform data with DCC-rig naming suggests a 3ds Max pipeline, and runtime-optimized clip structures are typical of Cal3D; checking nearby assets and examining the header is usually the fastest and most reliable way to identify the intended exporter.
