Debug Menu

V · EThis is an official VRChat information page!

It is written and maintained by VRCWiki Team.

The Debug Menu consists of multiple menus and consoles which are windows within the VRChat client that display various pools of data, and are used for troubleshooting. There are different debugging windows for Worlds, Avatars, and even OSC.

• M: Whether or not the player is the master of the instance
• L: Whether or not the player is the local player
• VR: Whether or not the player is in VR
• Group: The current group that the player is in. Grouping in this context is an internal networking system used to combine multiple objects together by distance so that their data can be sent together.
• Ping: The player's ping
• Intrvl: The amount of time between the player sending synced data about themselves.
• D: The current delay.

World debugging menus after 5 are restricted.

By default, only the creator of the world can access these menus. However, the world creator can allow others to see them by enabling World Debugging in the world's settings on the website.

Debug Menu 6 & 7

Debug Menu 6 displays all networked objects in the world. Showing networking stats of that object.

Debug Menu 7 displays the same information as Debug Menu 6, but sorts the objects from highest networking impact to least.

• Name: GameObjects name.
• Owner: The PlayerID of the owner of the object.
• Group: The current group that this object is in. Grouping in this context is an internal networking system used to combine multiple objects together by distance so that their data can be sent together.
• Sleeping: Whether or not the object is sleeping. Only objects with VRCObjectSync can sleep. Sleeping causes the object to stop transmitting data.
• Delay: The current delay of this object between the owner and the viewer.
• Size: The current number of bytes per serialization of this object. Every time it needs to sync, it will send this many bytes.
• Bps: A rough approximation of how many bytes per second this object is using up.
• Since Last: A running counter of how long it has been since the last time this object has sent data.
• Interval: A rough approximation of how many times this object tries to sync per second.

Debug Menu 8

Debug Menu 8 displays a panel on top of every synced object in the world. Each panel displays stats about that object.

• P: Ping of the owner
• Q: Quality of the data (100% is no dropped packets)
• O: PlayerID of the owner of the object
• G: The current group that this object is in. Grouping in this context is an internal networking system used to combine multiple objects together by distance so that their data can be sent together.
• Held: Whether or not this object is held, if it is a pickup
• Status: Displays various things about what this object is doing, such as Should Sleep, Player, Held, or Discontinuity
