Parameter Settings

Updated: 02/19/2024

You can adjust camera tracking items and Live2D parameters in nizima LIVE.
nizima LIVE allows for the adjustment of detailed aspects such as timing and links of parameter transitions that have previously only been manipulated in Live2D Cubism.

Upper Tab Menu

Feature	Operation
Setting Motions	Fine-tune the mapping between tracking items and Live2D parameters and how the parameters are reflected in the Live2D model.
Setting Motions Beta (ARKit)	Configure settings related to ARKit tracking items used in nizima LIVE TRACKER.
Physics	Adjust the motion scale for Live2D parameters for which physics operations are set.
Auto Playback	Set Live2D parameters for automatic and repetitive playback, such as breathing.
Other Settings	Configure the setting to synchronize the left eye blinking and eyebrow with the right eye blinking and eyebrow, and lip-sync settings.
…	Loads and saves parameter settings configured in nizima LIVE.

Setting Motions

Parameter selection panel (left side)

The following is a list of parameters that can be tracked in nizima LIVE and the Live2D parameters associated with them.

Selecting a tracking item switches the advanced settings panel on the right.

Press the ▲ to the right of the tracking item to close or open the associated UIs.

nizima LIVE automatically associates Live2D parameters with tracking items.
Each parameter that is associated is displayed by default under the tracking item.

Each parameter is indicated by the set name if the model data contains cdi.json, otherwise by ID.
The + button allows you to add new Live2D parameters to be associated with the tracking item.
With the × button, you can unassociate the tracking item from the Live2D parameters.

Tracking items dedicated to iOS are also displayed, with or without the connection of a mobile version.

Advanced settings panel (right side)

Parameter ID

The IDs of the parameters that the Live2D model has are displayed.

Motion scale

You can set the scale for body movements to be reflected in the movements of the Live2D model in the range of 0 to 200%.

Smoothing

You can integrate and correct minor body shaking, etc., and set the smoothness of the Live2D model’s movement in the range of 0 to 100%.

Setting Motion Scale and Smoothing

Invert playback

Inverts the movement of the Live2D model relative to the body’s movement.

Curve editor

You can edit the waveforms to see how the Live2D model’s movement changes in response to the body’s movements.

The point in the selected state is 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.

Operation	Contents
Left-click	Marks with a dot (point).
Right-click	Deletes the point.
Copy entire curve or Ctrl + C	Copies the shape of the entire curve.
Paste entire curve or Ctrl + V	Pastes the entire curve shape that you copied.
Undo or Ctrl + Z	Undoes the operation.
Redo or Ctrl + Y or Ctrl + Shift + Z	Redoes the undone operation.
Show/hide default values	Shows/hides the default values of the parameters of the Live2D model.
Enable/disable snapping	Enables or disables the point to snap (stick) to the grid, edge of the screen, etc.
Reset	Initializes the edited contents and returns the curve shape to its initial value.
Arrow keys	Use the up, down, left, and right arrows to move points.

Point

You can choose the type of the line that connects the selected point to the next point on the right from Linear, Step, Invert Step, and Bezier at the bottom of the screen.

Linear: A straight line connects the selected point to the next point on the right. Animation is constant and variable, with linear motion.
Step: The selected point and the next point on the right 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 next point on the right are connected by a horizontal straight line that matches the value of the next point on the right. The animation moves so that the previous and next pictures change in an instant.
Bezier: When selected, a purple [Bezier Handle] will appear. By grabbing the rounded edge, you can move it up, down, left, or right, and freely edit the shape of the curve.

Setting Curve Editor

Setting Motions Beta (ARKit)

You can set up tracking of movements that can be taken using an iPhone (ARKit).
The view and operation of the screen is the same as for motion settings.

Auto-link function
If the tracking item name in ARKit prefixed with “Param” and the parameter ID of the Live2D model match, the tracking item and parameter are automatically linked.

Example

The tracking item “EyeBlinkLeft” is automatically associated with the parameter of the Cubism parameter ID “ParamEyeBlinkLeft.” Cubism parameter IDs are case-insensitive when linked.
Either of the following is acceptable.

Physics

On the left side, the parameters set for physics operations are displayed.

Parameter ID

The IDs of the parameters that the Live2D model has are displayed.

Motion scale

You can set the scale for body movements to be reflected in the movements of the Live2D model in the range of 0 to 200%.
The closer to 200%, the greater the movement of the Live2D model relative to the body’s movements. 

Auto Playback

Parameter selection panel (left side)

+ button

You can add new Live2D parameters for which you want to set up auto playback.

Advanced settings panel (right side)

Parameter ID

The IDs of the parameters that the Live2D model has are displayed.

Repeat type

Loop playback

Note: This is the recommended way to add breathing to a model.
The movement goes back and forth repeatedly between the maximum and minimum.

Repeat playback

If the maximum is exceeded, the movement starts from the minimum and repeats.

Playback speed

The speed from the minimum to maximum can be specified in ms.

…

[…] in the upper right corner > [Save] or [Save as]
You can save your settings in .live.json format.

Other Settings

The setting to synchronize the left eye blinking and eyebrow with the right eye blinking and eyebrow and lip-sync settings are configured.

Eye parts

Synchronize the left eye blinking and eyebrow with the right eye blinking and eyebrow

Enable or disable the synchronization function.

Synchronization ratio

Set the criteria for winking and other out-of-sync situations.

Lip-sync

This function allows the Live2D model to move in response to audio input from the microphone.
This function is mainly used for mouth movements of Live2D models.

Enable lip-sync

Enables/disables the function.
When disabled, all of the following UIs are also disabled.

Enable Motion Sync set in Live2D Cubism Editor

The motion sync settings set in the Live2D Cubism Editor during model creation are used to move the model. Only models with motion sync settings can use this feature.
The following lip-sync support for “Mouthquake” and “Mouth Width”, time until mouth closes, and sensitivity adjustment are not supported for Motion Sync.
Learn more about motion sync settings in the Live2D Cubism Editor

Composite camera tracking with lip-sync parameters

It uses a blend of the microphone and camera values. This allows for expressions such as startled mouths and yawning mouths.

Input device

Switch the microphone.

Input boost

Amplifies the microphone input.

Input threshold

Set noise removal. Sounds less than or equal to the threshold are not reflected in lip-sync.
0dB: All sound is eliminated.

Time to close mouth

Set the time from the end of speaking until the mouth closes.

Sensitivity adjustment automatic setting

Set the scale for the corresponding vowel.
Follow the guidance and it will be set automatically.

Input value scale

Manually set the scale of the corresponding vowel.

Lip-sync output confirmation

Output results can be checked for (A), (I), (U), (E), (O), (Vertical), and (Horizontal).
