ke.exports

Export utilities for converting KangEngine’s internal SkeletonMotion representation into common file formats. These lightweight serialization helpers can be used independently of interactive applications.

BVH

The generated BVH uses XYZ root position channels and ZYX local rotation channels. Joint names and hierarchy offsets come from the motion’s SkeletonTree. Leaf joints have no End Site block.

save_motion_bvh

kangengine.exports.bvh.save_motion_bvh(path: str | Path, motion) → Path[python]

Write a SkeletonMotion to a BVH file and return its path.

Return type:

Path

motion: ke.animation.SkeletonMotion = ke.asset.BVHLoader.load_motion(
    bvh_path="input.bvh",
)
ke.exports.save_motion_bvh(path="output.bvh", motion=motion)

save_motion_bvh is the only public BVH export function. Text/byte conversion helpers remain private implementation details. SMPL and SMPL-X motion export is not currently provided.
