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\VizEngine\VizEngine-0.cfg.

2. Close Viz Engine. 

3. Open the Viz 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.

4. 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.

5. Depending on the transport protocol the flag use_trackinghub must be set to 1 or 3. 

   • use_trackinghub = 1 is used for the standard UDP protocol. 

   • use_trackinghub = 3 is used for tracking data embedded into the NDI stream.

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

If more than one network adapter is present on Viz 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.
