Motion Layer Tracks

The Motion Layer tracks are important tracks for fine-tuning an actor's motion. You may generate simple Key Frame Animation or add Animation Layers to an existing animation clip. Basically, all the sub-tracks under the main Motion track, are motion layer tracks.

Motion Layer Concept

Motion Clip and Transform Key

Given a motion on a character- before the motion is modified with a Transform key.

The motion will be modified after being affected by a Transform key.

Motion Clip and Sprite Switch

Given an existing motion of a character - before the motion is modified with a Sprite switch.

The motion will be modified after being affected by a Sprite switch.

Key Frame Animation

To fully understand Key Frame Animation, you will need to remove all the motion clips in the Motion main track. Then create your own key by key motion for the actor.
Follow the steps below to generate Key Frame Animation.

1. Select a character, and go to the desired time frame to create the first motion key with the Body Key Editor.

2. In the Body Key Editor window, utilize the Pose and Body mode to set a motion key.
   

3. Go to another time frame.
   

4. Add another key.
   

5. Play the project to see the results. The transition effect will automatically be generated between these two keys.
   

Layered Animation

Another powerful feature of the Motion Layer is to fine-tune the motion clips on the Motion main track. The keys on the Motion Layer track have the highest priority for the bone offset.

1. Apply a motion clip to the character.
   
2. Go to the middle time frame of this motion.
   
3. In the Transform main track, add a motion layer key to any desired time frame (if you don't set any other keys later on, then this key will affect all the latter motions).
   
4. The key will affect the entire motion clip.
   

Restoring Animation from Motion Layer Keys

If you need to eliminate any influence from previous transform layer keys, then you may use the Default Pose feature to set an initial data to all the virtual bones, so that the original pose can be retrieved.

In the last example, the character bends from the middle of the motion up until the end of the clip. Please follow the steps below to reset its pose at the end of the motion:

1. Go to the end time frame of the motion.
   
2. In the Body Key Editor, click the Default Pose button to set initial keys to all the virtual bones.
3. The character will gradually return to the up straight pose at the end of the motion.
