Running

Download and Run Nexus LU Launcher

Uchu requires an unpacked LEGO Universe client distribution to work. Nexus LU Launcher (download) is supported by Uchu. Running Nexus LU Launcher and running the initial download will allow Uchu to automatically configure the client.

Download and Run Uchu Tool

Uchu Tool downloads can be found in the releases tab on GitHub. When run, it will automatically fetch the latest release of Uchu and start it. Unless Nexus LU Launcher was not used, not configuration changes will be required.

Add Your User

When you've got your server up and running, it's time to create a user account. If you're on Windows, find the window titled Authentication. On Linux/macOS, you just need the one window in which the server is running. Type /adduser <username> and press enter to create a user (don't include the <>). Uchu will prompt you for a password. You can set your permissions using /gamemaster <username> <level>. The highest level available is 9.

After this, you are ready to open LEGO Universe and play!
