I noticed when going into each bone to delete keys and redo them, that with no keyframes, certain bones are still moved in later frames, because their parent bone is changing their position in the animation.
Of course, you can change a bone's posture without moving its child bones, by enabling bone compensation. You can then create keyframes for this.
Would it be possible then to edit a keyframe and change it from no compensate to compensate?
That way, I could simply edit a keyframe that moves other bones with it, and make it not do that anymore, instead of having to delete the keyframe, then re-posture the bone with compensation on, and make new keys for it. Just so its child bones are no longer effected by its movement.
