BIP File Format Explained

The .BIP format is an Autodesk Biped motion file used by Character Studio / Biped in 3ds Max. It is the standard format within 3ds Max for saving and loading animation data for Biped objects.

BIP File Format Details What It Stores It stores comprehensive animation data, including keyframes, footsteps, and limb rotations for Biped hierarchies. It does not contain mesh geometry, textures, or rigging constraints outside of the specific Biped skeletal structure. Primary Use Cases Storing motion capture (mocap) data for character animation. Transferring complex movement sequences between different 3ds Max scenes. Building animation libraries for reusable character behaviors. Managing Footstep based animation sequences within Character Studio. Strengths Designed to store complete Biped motion data for reuse in 3ds Max. Seamless integration with the 3ds Max Biped system. Supports retargeting between Biped rigs, though results may require adjustment for differing proportions. Works with Biped's animation layering and Motion Mixer tools for non-destructive editing. Limitations Proprietary and primarily supported within 3ds Max, with limited third-party support. Incompatible with standard Bone systems or custom rigs without conversion. Common Software Support Native creation and editing are exclusive to 3ds Max. Motion data can be exported to other engines via FBX conversion, but the raw .BIP remains local to 3ds Max.
