How to set parameters for Live2D model

Motion magnification / smoothing settings (for beginners)

If you are a beginner, let’s set this up first! The Live2D model will move more smoothly.

1. Click Parameter Settings from the menu in the main window.

2. The parameter setting screen is displayed.

On the left side of the screen, the one surrounded by a square is a list of parameters that can be tracked on nizima LIVE. Below that, you can associate the parameters of the Live2D model corresponding to that movement. (It is automatically linked by default)

Movement setting beta (ARKit) is a tracking parameter for iOS only.

For example, in the screen above, “angle X” and “body rotation X” are linked to “left and right movement of the face”, so if you turn your face to the left and right, you can see the “angle X” and “body” of the Live2D model. You can move the “Rotation X”.

3. Select the parameter you want to adjust.

4. Adjust the “Motion Magnification” while moving in front of the camera and moving the Live2D model.

The closer it is to 0%, the less the Live2D model will move with respect to body movements.
The closer you get to 200%, the more the Live2D model will move with respect to your body movements.

5. Similarly, adjust the “smoothing” while moving the Live2D model.

The closer it is to 0, the more the body movement will be reflected in the model movement without correction.
The closer it is to 100, the slower the reaction will be, but it will integrate and correct small shaking of the body and move the model smoothly.

  • If your Live2D model wiggles, you may be able to improve by increasing this “smoothing”.

Curve Editor Settings (for intermediate and advanced users)

1. Perform steps 1 to 3 of “Motion magnification / smoothing settings (for beginners)“.

2. Edit the curve to see how the output changes in relation to the input. Edit by dragging the point you hit anywhere.

Points in the selected state are purple. The green dot on the waveform is the current value.
Click […] in the upper right corner of the curve editor to display the various operation buttons.

arrow keyUse the arrows up, down, left, and right to move points.

With Linear, Step, Invert Step, Bezier at the bottom of the screen, you can select which type to connect to the point to the right of the selected point.

Linear: A straight line connects the selected point and the point to the right of it. The animation is constant and variable, with linear movements.
Step: The selected point and the point to the right of it are connected by a horizontal straight line that matches the numerical value of the selected point. The animation moves so that the previous and next pictures change in an instant.
Invert Step: The selected point and the point to the right of it are connected by a horizontal straight line that matches the value of the point to the right. The animation moves so that the previous and next pictures change in an instant.
Bezier: Select to display the purple Bezier handle. You can move it up, down, left and right by grasping the rounded part, and you can freely edit the shape of the curve.

Curve Editor Application Examples

Align the curves of the right and left eyes

1. Select “Left Eye Open/Close” from the tracking items on the left side of the panel.

2. While actually moving the model, adjust the left eye opening with the curve editor.

3. When adjustment is complete, click on “…” in the upper right corner of the Curve Editor and click on “Copy Entire Curve”. The curve shape of the left eye opening/closing has been copied.

4. Select “Right Eye Open/Close” from the tracking items on the left side of the panel.

5. Click “Paste Entire Curve” from “…” in the upper right corner of the Curve Editor. The curve shape of the left eye open/close is pasted, and the open/close adjustment of the right eye and the left eye is now the same.

Improve the model’s mouth puckering.

If the model’s mouth cracks open and closes when the mouth is completely closed or when the model shakes her head while the mouth is closed, the following procedure may help.

1. Select “Mouth Open/Close” under “13 lip-sync”.

2. In the Curve Editor, adjust the curve so that it looks like the following

Left-click to hit a single point and move it so that it is at the lowest vertical axis and 25% horizontal axis.

3. Actually move the model to see if it has been improved. Adjust the curves as necessary.


How to use the collaboration function

To send and receive tracking data and Live2D model data of other users using the collaboration function, the host creates a “room” and participants enter the “room”.

    Please see the price plan for details such as function comparison with the paid plan and price list.
  • Versions prior to 1.1.0 and 1.1.0 or later cannot collaborate.
