UE Examples & Sample files
These examples are built in the Switchboard environment for nDisplay.
To view the configurations properly, use notepad++ in “json” language.
To work exclusively on the .ndisplay file instead of the .uasset in the UE editor, make sure to empty the parameter:
"assetPath": ""To enable movement control via WASD and mouse, set
bFollowLocalPlayerCamerato true.To use offsets in windows and viewports, make sure to set the node’s
fullscreenparameter to false.If using the (VWF) format, make sure switchboard is set to Directx 11.
If using remote desktop control (e.g Teamviewer), make sure its not modifying window resolutions and coordinates (scaling, fit to screen..etc).
