nDisplay Black Screen with Compiled Project (Works in Editor)

[DorianMouais]

Starting to think you can’t use nDisplay with a compiled project

The reason why I wanted to do this was to allow users to change levels without having to wait for everything to load in the editor.

Here are some promising links I’ve found :

Launching packaged (windows exe) projects with switchboard

Figured out how to make the script work across multiple systems! All you need to do is set the outputs to be under different hosts in the nDisplay configurator in Unreal Editor, and set the IPs of your machines on the Details panel for each output! [image] Note, you can change the IPs after exporting by editing the .ndisplay file with a text editor and changing the ‘host’ values under the node object to your desired IPs: [image] Also, another thing I discovered is that you can run an execu…

How to run nDisplay by script or command line

If you launch the switchboard launcher and listener and execute the project from there, you can see the command being executed on the listener. You can use that in a .bat to launch the project in “ndisplay mode” or you can add the launch arguments to a shortcut. Here is an example on how to launch a built project: “{YOUR_PROJECT_PATH}\Built_project.exe” -game None -messaging -dc_cluster -nosplash -fixedseed -NoVerifyGC -noxrstereo -xrtrackingonly -RemoteControlIsHeadless -StageFriendlyName=“N…

nDisplay - Is it possible to install only Switchboard Listener on my rendering machines without installing the full Unreal Engine?

I think I’ve solved it,I did not put swicthboardlistener in the win64 folder before, so I could not find the corresponding file. Now I can normally use nisplay on the node pc without installing UE5.

Switchboard and nDisplay with Shipping Build

Running shipping builds with nDisplay is simple, there’s two ways: Just write your own start script instead of using switchboard. All SB does is send a command line string to be executed on the nodes, just grab that one (from settings), ssh to all your nodes and execute it. Back before switchboard was a thing this was the common way to start nDisplay nodes Switchboard can deal with executables lately, at least I think I’ve read a commit that said it could. Haven’t tested it, but even if…

Any insights or additional tips on how to effectively use nDisplay with a compiled project would be greatly appreciated !
