Live2D Cubism Editor Communication

⚠️ This functionality is only useful for Live2D riggers!! ⚠️

VTube Studio can connect directly to the Live2D Cubism Editor using the Live2D Cubism External Application functionality.

This makes the following integrations possible:

• You can send tracking data from VTS into the Live2D Cubism Editor. Having live real-time tracking movement in the Live2D physics preview window in Live2D Cubism makes setting up physics much easier since you can directly see how your physics setup reacts to face tracking movements without exporting the model.
• VTube Studio can automatically detect when you export models from the Live2D Cubism Editor. When a model is exported, VTube Studio can then automatically copy the model over into the VTube Studio model folder.

How to set this up

First, you have to make the Live2D Cubism Editor API is turned on. Select File => External Application Integration settings... and click the play icon to start the API.

Once that is done, start the connection to the Live2D Cubism Editor API in VTube Studio (first settings tab).

VTube Studio should now automatically try to connect/re-connect in the background. When it connects for the first time, you have to check the "Permission" checkbox in Live2D Cubism. Now, VTube Studio will have full access to the Live2D Cubism Editor API. VTube Studio will remember its own token so you only have to do this once.
