BVH Import
This import filter enables you to use Biovision motion capture data in your scenes. If you load a bvh file, a keyframe’s hierarchy of bones appears in the Object manager. In the Timeline you’ll see that each bone has a position and rotation track, with a key for every frame. With complex skeletons, there are thousands of keys and the animation may not play back smoothly on slower processors.
To combine the bones with the 3D model, first move, scale and rotate the model to fit the bones.
This is much simpler than the reverse, i.e. adapting the bones to fit the model, due to the bones’ keyframes. Now place the bones and model in the same hierarchy, and the bones then control the model. As mentioned previously, you may experience difficulties when using many keyframes. In this case, reduce the number of keyframes.
