An XAF file is mainly used 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 most often consists of 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 mainly contains animation instructions without any character geometry, using timelines, keyframes, and transform tracks to rotate or adjust bones referenced by names or IDs, sometimes with interpolation data for smooth blends, and whether it stores one clip or several, the purpose stays the same: defining how a skeleton moves 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 identify what XAF you’re dealing with, the quickest trick is to rely on a self-describing text check by opening it in a simple editor and seeing if the content is readable XML—tags and meaningful words indicate XML, while messy characters suggest binary or a misleading extension—and if it is XML, skimming the first lines or searching for terms like Max, Biped, CAT, or Character Studio plus recognizable rig naming can help verify a 3ds Max workflow.
If the file openly references “Cal3D” or uses XML tags that fit Cal3D animation conventions, it’s likely a Cal3D XML needing its corresponding skeleton and mesh, whereas dense bone-transform data with DCC-rig naming points toward a 3ds Max pipeline, and runtime-optimized clip structures tend to indicate Cal3D; checking nearby assets and examining the header is usually the fastest and most reliable way to identify the intended exporter.
