Configure

Project settings shared by the team, and the personal name, color, and password each person sets.

Two places in Unreal. One is committed with the project. The other stays on each machine.

The server has to be running before anyone can connect. Setup for each platform is in the Server section.

Project settings

Shared by the whole team and saved in Config/DefaultEditor.ini.

Project Settings > Plugins > Editor Collaboration

Server URL and room in Project Settings. The room is shared by the team.

Setting	What to put
Server URL	`ws://192.168.1.10:7878/ws` on a local network, or `wss://collab.example.com/ws` behind HTTPS. The value must start with `ws://` or `wss://`.
Room	Leave empty to use the project name. Set it when several projects should share a room, or when one project should be split.

Commit that change once. Everyone who pulls the project then points at the same server.

Personal settings

Stored under Saved/ and never committed.

Editor Preferences > Plugins > Editor Collaboration (Personal)

On the first connection the plugin also creates Saved/EditorCollaboration/ClientId.txt. It keeps your messages, comments, and file marks yours across restarts. Do not copy it to another machine.

Each person sets a display name and a color, and chooses which indicators to show.
