Plugin

What the Editor Collaboration plugin shows in Unreal, and where to configure it.

The plugin runs inside the Unreal Editor. It connects to your server, draws everyone else's presence, and lets you chat and comment without leaving the editor.

Cameras in the viewport, who is online, chat, and a comment pinned on the map.

Configure

Server URL for the team, and name, color, and password for each person.

Work together

Badges, Go to, cameras, graphs, Sequencer, and look-here markers.

Chat

Send messages, mention someone, and load older history.

Comments

Pin a thread on an actor, a graph node, or an asset.

Files and locks

Pencils for edits, soft locks, and Git LFS locks.

Where things live

What	Where
Who is online	Badges at the top right of every window, next to the project name
Collaborators panel	A badge, the Collab toolbar button, or `Window > Tools > Collaborators`
Chat	Speech-bubble button, or `Window > Tools > Chat`
Comments	Pin button, Comment toolbar button, or `Ctrl+Alt+C`
Look-here marker	`Ctrl+Alt+P`, then click in the viewport or a graph

A map or asset the other person has not saved, or has not pushed to Git yet, cannot be opened on your machine. The editor says so.
