Read Only Model File

VTube Studio needs write access to your model's .vtube.json file to save configuration changes such as parameter settings, hotkeys, expressions, and model position.

If the file is read-only, VTS will still load the model but will not be able to save any changes you make.

For Live2D items, VTS will refuse to load the item entirely if the file is read-only.

Common Causes

• The file was extracted from a .zip or .rar archive and inherited a read-only flag.
• The file is on a read-only drive or network share.
• File permissions were changed manually or by another application.

How to Fix

Right-click the .vtube.json file, open "Properties", and uncheck the "Read-only" attribute.

After removing the flag, reload the model in VTube Studio.
