Restore old VTS Versions

Starting with updates after VTube Studio 1.26.11, you will be able to restore old versions of VTube Studio on Steam (macOS and Windows). This will be possible for versions of VTube Studio released after June 14th, 2023.

In general, I would recommend always staying on the newest version and reporting any bugs you find in the VTube Studio Discord so they can be fixed as soon as possible. But in some emergency situations, it can make sense to do a temporary rollback to an old version that worked better for you.

Keep in mind that for VNet Multiplayer to work properly, all collab participants should be on the same VTube Studio version, although some versions may be compatible if they use the same VNet netcode version.

If you are on an old version branch of VTube Studio, Steam will no longer automatically update VTube Studio and you will not receive any further updates and bugfixes until you switch back to the normal public version.

There is also no guarantee that these old Steam versions will stay compatible with VNet and the iOS and Android apps forever, so only roll back if there is no other option for you and return to the current public version again as soon as you can.

How do I restore old versions?

⚠️ Important: Before switching to an old version, make safety copies of all your models, items and backgrounds!! That means make copies of your Live2DModels, Items and Backgrounds folders somewhere outside of the VTube Studio Steam folder. Switching versions will not delete any files, but it's best to be on the safe side since there HAVE been reports of Steam updates randomly deleting model files!! ⚠️

Old versions are available as Steam beta branches.

In your Steam game library, right-click VTube Studio and select Properties... → Betas. There, you will find a dropdown list showing old versions.

You can change back to the normal branch at any time by selecting None as beta.

And again, please make sure to have safety copies of all your assets BEFORE attempting to switch to old versions of VTube Studio.
