Viz Engine needs to be correctly configured to receive tracking data from the Tracking Hub. For correct configuration, the Viz Engine configuration file must be edited manually following these instructions:

1. Locate the Viz Engine configuration file. This is normally C:\ProgramData\vizrt\viz3\VIZ-MYHOSTNAME-0-0.cfg where MYHOSTNAME is the hostname of the PC the Engine is running on.

2. Open the Engine configuration file in a text editor like Notepad, the configuration file is a text-file and must be saved after editing as a text-file.

3. Locate the Camera section in the configuration file and make edits as follows:

   • The flag trackinghub_port = 3000 must be set to a valid and accessible port.

   • The flag use_trackinghub = 1 must be set to 1.

When this is done, the Engine no longer waits for tracking data from the discontinued Viz IO. Instead, the Tracking Hub port is opened and the Engine sends live signs to the Studio Manager and appears in all dialogs where an Engine can be selected.

If more than one network adapter is present on the Engine, the user can bind the live signs and tracing data to a specific network interface. The flag trackinghub_adapter = <IPADDRESS> (for example: 10.211.1.65) must be configured to the adapter IP that should be used. If the flag is empty, the first adapter is used.
