How do described motions work?

Short answer
You type what your character should do, like "shake off water from head to tail". Bake3D writes a motion for that character's own skeleton, checks it and saves it as an animation you can play and export. Each one costs 10 credits.
In more detail
The motion engine turns your words into a short motion program. The program moves joints by their job names, such as tail, head or left front leg, not by bone names. That is why the same words can work on very different bodies.
Then the engine checks the motion, for example that arms and legs do not pass through the body, and fixes what it can. By default a described motion is a 4-second loop.
Playback is exact. The same motion on the same rig gives the same pose at the same moment, every time. That matters in games, where a clip has to loop the same way each time.
Tips for good results:
- Describe one action, or a short chain of them: "sits down, then scratches behind its ear".
- Name body parts your character really has.
- Say how fast and how big: "slowly", "a small hop".
Each described motion costs 10 credits. An optional review round, where the engine looks at pictures of the motion and revises it, costs 5. You can try it free on the demo characters with Direct it, 3 times a day with a free account.
Limits: faces have no expressions yet, and a motion is a 3D animation clip, not a video.
