In RealityHub terminology, a Host refers to a server configuration that hosts an Engine; in other words, it is the computer you install the Reality Engine. It is essential to add a Host for accessing your Reality Engine(s) and control them via RealityHub.

The image above shows the default Hosts interface.

To add a Host:

  • Go to Main Menu > select the Configuration

  • Select the Hosts under the Engines

Find your hostname:

  • Run the Command Prompt on your Windows

  • Type hostname and click enter

  • Copy your hostname


  • Turn back to Hosts configuration

  • Click ➕ to Add a New Host

  • Paste the Host Name you copied earlier

As soon as you define a hostname; RealityHub adds a default Display Name, IP Adress, Port, Cache Directory, and Installations.

Display Name: You can define a specific name for your Host to better organize your setup. Your computer’s hostname (in our case it’s ZDHQ-AER3) might not be useful in recognizing the purpose of your engine. To set an example, if you are utilizing multiple engines in a studio, you might want to define a specific name for your Hosts such as Studio A, Camera B, etc.

Please keep that in mind, the Host Name refers to a server’s hostname, it has to belong to your server configuration.

  • IP Adress: IP address of a server you installed the Reality Engine.

  • Port: 6666 is the default port for the Reality Engine. If you changed the port number during the installation, you must provide that specific port number.

  • Cache Directory: A directory you can use for caching your Reality Engine projects

  • Can Cook: Disabling and enabling the Cook operation for your Engine. See Cook Manager

  • Enable Launch: This option gives you the ability to specify which Engine can be launched

  • Installations: You can choose or redefine the directory you installed the Reality Engine.
