Motion Quality Improvement Tips

This section explains how to make a move when attaching motion to the model you have created to make it work better.
It is designed for beginners, so please refer to it if you are new to putting on motions.


Instead of adding the face movement by itself, the X and Z of the body are also added to the face movement.

If you only turn your face around, you will look like a robot.
Make your body move in accordance with the movement of your face.


Shift the timing of face XYZ and body XYZ with inertia in mind

If the face and body move at exactly the same time, it still looks like a robot.
Let's assume movements such as “turning your face will cause your body to follow you later” and “turning your body will change the direction of your face”.


Recoil, apply brake

Humans are not able to stop moving instantly and with a snap. It is easy to understand when you stop your own arm in a tight fit.
I'm going to stop, then go a little further, then go back a little. When it gets to the point where you are thinking of stopping, the brakes are applied and the movement slows down...etc.
It is a small detail, but when incorporated in places, it looks like a natural movement.


Understand natural human movement

People often blink when they turn their faces or change their eyes.
When moving while speaking, the face, body, and arms should move as you begin to speak to create a more natural movement.


Enhance a person's facial expression

One of Live2D's strengths is its ability to smoothly change facial expressions.
Subtle eyebrow movement can be finely applied for better results.


Give the movement a boost

The motion will be better if you are aware of large and small moving parts and give the motion a fuller feel.
Be aware that you should be quiet while waiting, and when you move, you should move clearly enough that you can see that you are moving.


Make the right moves for your character

Vary the way you add movement for each gender and age group.

Example: Adult male characters

• The movement is sturdy and calm. Try not to let it wobble.
• Reduce the frequency of tilting movements, such as face Z, to avoid cuteness.

Example: Young female characters

• Make sure to move the entire body in large movements.
• The “tilt your head back” movement is a cute one.
