I don't know my version or loader
This mod enables your Minecraft client to use the VMC protocol to manipulate vtuber models.
This mod includes an API for other Minecraft mods to create and implement additional BlendShapes to be transmit over the same connection.
BlendShapes
BlendShapes are numerical values sent over VMC and are used by vtubing applications to activate toggles, move the model, etc. By default, the mod creates 20+ BlendShapes and sends them over 127.0.0.1:35940.
These BlendShapes represent various states and events from the in-game player, including:
- relative health
- sprinting
- sneaking
- taking/dealing damage
See the gallery for an example of using the player's actions to activate toggles.
Disclaimer and Compatibility
This mod is made specifically for use with the open-source vtubing application Inochi Session and has been tested with VMC Protocol Monitor.
Not all VMC applications are guaranteed to work with VMC-MC, but the following are reported to be compatible implementations:
- Inochi Session
- UniVRM (requires compatibility mode)
VMC is an extension of Open Sound Control (OSC), thus making VMC-MC hypothetically compatible with OSC applications as well.
