Unofficial OSC Documentation

Disclaimer: This is an unofficial record of what I've learned about the VRChat OSC and its parameters. WIP

The goal of this page is to include **every ** avatar parameter out there

---

All testing was done with python-osc so your results may vary across other osc platforms

Setable Parameters (Parameters that can be set from another program or app)

• Official Parameters (Sources: osc-as-input-controller, osc-trackers, osc-eye-tracking)

Parameter Path	Parameter Name	Parameter Description *modified from the official wiki 1.0 indicates a Float value while 1 on its own is synonymous with True	Parameter Data Type *guess due to non-functioning parameter	Range *guess due to non-functioning parameter	Notes Float values: Make sure to send the value as a Float or the game occasionally interprets it as a bool Boolean values: You can also send 1 or 0 respectively

/input/Voice	Voice	Toggle Voice - the action will depend on whether "Toggle Voice" is turned on in your Settings. If so, then changing from 0 to 1 will toggle the state of mute. If "Toggle Voice" is turned off, then it functions like Push-To-Mute - 1 is muted, 0 is unmuted.	bool	[True, False]
/chatbox/input s b n	input	Input text into the chatbox. If b is True, send the text in s immediately, bypassing the keyboard. If b is False, open the keyboard and populate it with the provided text. n is an additional bool parameter that when set to False will not trigger the notification SFX (defaults to True if not specified).
