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 Joints appears in the Object Manager. In the Timeline you will see that each Joint 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 Joints with the 3D model, first move, scale and rotate the model to fit the Joints.
This is much simpler than the reverse, i.e., adapting the Joints to fit the model, due to the bones’ keyframes. Now place the Joints and model in the same hierarchy, and the Joints then control the model. As mentioned previously, you may experience difficulties when using many keyframes. In this case, reduce the number of keyframes.
