Viz Engine needs to be correct configured in order 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 will normally be C:\ProgramData\vizrt\viz3\VIZ-MYHOSTNAME-0-0.cfg where MYHOSTNAME will be 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.
   If 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:

must be configured to the adapter IP that should be used. If the flag is empty, the first adapter will be used.
