nDisplay is not linking correctly the Camera Components inside the nDisplayConfig.uasset with display viewports when their Projection Policy is set to Camera. This issue appears when a packaged game is launched from the Switchboard as "Packaged Game".

When launching a packaged game from the nDisplay Switchboard, the nDisplayConfig file fails to link the cameras to the viewports. Inside the log generated by the Switchboard an error is displayed that indicates that cameras referenced have not been found.

This issue was not happening in 5.3.

1- Create an nDisplay config asset.

2- Create 3 cameras. Name them front, left, right and rotate left 90º and right -90º.

3- Create a new node and create 3 viewports. Call the viewports left, right and center. Each viewport of size 1920x1080 and position them one next to the other. Viewport Left to position (0,0), Viewport center to (1920, 0), and viewport right to (3840, 0).

4- Change all the projection policies of the viewports to Camera type and set the camera to its corresponding.

5- Build/package the application.

6- Open the Launch Switchboard, create a new Configuration of the project and add a new nDisplay device. Select the created nDisplay file, and set "Launch As" to Packaged game.

7- Open the editor listener, connect to it from the Switchboard and launch it by pressing "Start Unreal".

8- You will see that the game launches correctly, the nDisplay selected is also correct, but all 3 displays show the same camera (front), not the selected cameras configured previously in the nDisplay file.
