Physics FPS

You can select from 30FPS and 60FPS.
It represents the internal calculation settings for the physics operations of the model displayed in the window.
By matching the settings in the Live2D Cubism Editor at the time of model creation, the shaking width of physics calculations, etc. can be made the same as that displayed in the Live2D Cubism Editor.
In Live2D Cubism Editor 4.2 or later, if the calculated FPS is exported to the physics settings file, that value will take precedence.

Tracking quality

Lowering the number will reduce the quality of tracking, but it may make the Live2D model move more smoothly.


他のアプリケーションよりもnizima LIVEが前面に表示される機能です。
The main applications include the ability to check the movement of a Live2D model while playing a game during game distribution, or to create a simple layer structure on the desktop for easy distribution instead of creating layers in OBS.
