An XAF file typically operates 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 store geometry, materials, textures, or scene elements, expecting an existing skeleton inside the target application.
Using an XAF usually involves bringing it into the right 3D environment—whether that’s 3ds Max using its animation tools or any pipeline built around Cal3D—and problems like twisted or misaligned motion arise when the target rig doesn’t match, making it helpful to inspect the top of the file in a text editor for “Cal3D” tags or 3ds Max/Biped/CAT references that reveal which importer it needs and which skeleton must accompany it.

An XAF file is generally an animation-only asset that holds the data needed to move a rig but not the character or scene, containing the “motion math” such as timelines, keyframes, and tracks that apply rotations—and sometimes position or scale—to named bones or IDs, along with interpolation curves for smooth transitions, whether it represents one action like a walk cycle or multiple clips, all describing how a skeleton changes over time.
An XAF file does not typically include 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 open it as 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 point toward a 3ds Max animation workflow.
If you find explicit Cal3D wording or XML attributes that describe Cal3D clip/track structures, you’re likely looking at a Cal3D XML animation that expects matching Cal3D skeleton and mesh files, whereas detailed DCC-style transform tracks and familiar rig identifiers are more in line with a 3ds Max workflow, and efficient game-oriented clip formats hint toward Cal3D; external associated files and especially the first lines of the XAF provide the strongest confirmation.
