Camera to nDisplay viewport

Development Platform & Builds XR Development
1

Hi Folks,
first I have to say that I’m new to nDisplay, but already got the InCameraVFX example to work.

I’m trying to output 4 cameras straight to dedicated viewports in nDisplay. I don’t need camera reprojection, frustums or tracking. Just 4 static cameras in Unreal, assigned to 4 viewports in nDisplay.

To keep it simple at first, i just started with one camera. As described in the nDisplay documentation I created a new blueprint to set my camera to the nDisplay viewport.

But even with my pretty simple configuration, nDisplay only shows a black window.

I’m currently running UE 4.26.0. My Config file and Blueprint are attached below.

thanks!
Steven

I’ve taken a look in the logfile and found the following line:

[2021.02.26-17.02.47:928] 26]LogDisplayClusterRender: Warning: No camera found for viewport ‘vp_demo’

Do i need to reference the “DisplayClusterProjection Module API” Somewhere?

you need to call DisplayClusterProjectionModuleAPI - SetCamera .You can do this in the level blueprint.

I solve this problem.

Simply add a [camera] item to your config file.

ex) [camera] id=“camera_static” loc=“X=0,Y=0,Z=0”
