The first big new feature is Split Live2D items!! You can have split Live2D items now with a front and back part, so they're wrapping around the main model and make it look like you're really wearing the item.

Internally this works by splitting the Live2D item at a certain layer into a front/back part and then setting orders within the main model for those parts separately.

VTube Studio comes with a few items that already have this set up so you can play around with them. But, you can also easily set this up for your own Live2D items.

Isn't that cool!?

Next, you can now pin stuff to other people during collabs or take their items now. This also works with the split Live2D items. Not much else to explain here. People requested this one a lot!

Also, there are new expression parameter modes! When you create an expression, you can now select between "overwrite" (standard), "add" and "multiply".

"Add" just adds a static value to that parameter at the end (after tracking) and "Multiply" multiplies the Live2D parameter by the set value. The value can also be negative, so you can do a lot of interesting stuff with it, like having hotkeys that invert the tracking.

Oh and there's mocopi tracking in VTube Studio now!!??! It's a bit crazy to use that in 2D models, but the Sony mocopi team reached out and asked if it could be added. They even made a really pretty example model you can use for free.

For more info on that, check this page: https://github.com/DenchiSoft/VTubeStudio/wiki/mocopi

There's even more stuff:

• You can now turn expressions on/off WITHOUT making hotkeys for them.

• You can now create expressions and expression hotkeys for items super easily.

• You can now set ArtMesh recolors for items directly.

• You can set fixed positions for VNet collab participants (who's in front).

• VNet collab guest model positions will now be remembered when guests leave and re-join (if you control their positions).

• There's now detailed upload/download statistics so you can see how far along VNet model upload/downloads are (can sometimes be useful when models take long to upload).

• "Alt" is supported as a hotkey now.

• You can now turn on pin notifications that show you exactly which layer in your model items pin to.

• You can set items to only pin to one specific layer in your model. Useful to actually get those hats to pin to your head and not some weird hair overlay layer (though that can look pretty funny too).

And then there's some more stuff and a bunch of bugfixes.

Finally, there were some adjustments that had to be made to the watermark in VTube Studio so the app stays compliant with the updated Live2D SDK licensing terms. For more information, please check this Tweet: https://x.com/VTubeStudio/status/1930366944441511953

Sorry for the inconvenience.

And if you have questions, as always, please ask in the Discord: https://discord.gg/VTubeStudio

1. Fixed microphone lag. You should no longer have to restart your mic repeatedly to fix lag issues or sound glitches. Disconnecting/Reconnecting USB microphones should also no longer break the microphone tracking.
   
2. Fixed rare issue that would sometimes cause Expressions to fail to be set correctly when activated during one-shot Animation playback.

• VNet Multiplayer functionality has been fixed.
  
• The Spout2 Background works again now on any GPU.

• Better tracking for eye-related parameters (eye movement and winking in particular).
  
• Better performance, responsiveness and expressiveness in general.
  
• Restores compatibility with new NVIDIA RTX 50-series GPUs.
  
• Finetuning for blendshape calibration. For more info: https://github.com/DenchiSoft/VTubeStudio/wiki/NVIDIA-Webcam-Tracker#finetuning-and-calibration
  
• Can also be used with VBridger with all included blendshapes.

• Zoom/Rotate around Live2D model center.
  
• Zoom/Rotate around mouse cursor (NEW).

• Warning popup before deleting parameter mappings and hotkeys to prevent deletion by accident.
  
• VNet: Warning popup when upload fails because file path is too long for at least one file.

• Warning is now shown before files dragged into VTS window are loaded. This can be turned off.
  
• General Item Settings: Configure how drag & drop is handled and enable/disable file types for drag & drop.
  
• Fixed bug that caused VBridger tracking to buffer/glitch when data is received during model load.
  
• Live2D Editor API is no longer in beta.
  
• Option to remove gear icon entirely from Web Items.
  
• Fixed issue where "tracking lost idle animation" would glitch for non-zero delay times.

• Support for the Live2D Cubism Editor API[github.com]. This allows VTube Studio to directly send tracking data into the Live2D Cubism Editor. This makes it much easier for model riggers to test physics setups without repeatedly exporting the model.
  
• Added tooltips to some of the main menu options and config options. Tooltip coverage will be expanded in the future to hopefully make the UI a little less confusing.
  
• Fix for issue where VTS watermark would show up even when DLC was purchased.
  
• API: New API for controlling post-processing effects[github.com].
  
• Emote-Dropper: Support for renamed emotes.
  
• Many smaller bugfixes.

• VNet: Increased max. collab participants to 6
  
• New VFX: Line scan
  
• New VFX: Fake low FPS
  
• New VFX: Fake encoding errors
  
• New VFX: Old film effect
  
• Added back previously removed model glitch effects and added a few more. To use them, you have to manually enable them in the VFX settings found on the effects UI. This will also show a warning.
  
• macOS: Hotkeys now also work when VTube Studio is in the background on macOS.

• VTube Studio now works on macOS Sonoma again.
  
• Fixed an API bug that made authentication fail sometimes.
  
• Fixed bug that made on-screen hotkey 8 not work sometimes.
