UE Examples & Sample files

Download here sample VIOSO export files (mpcdi/vwf)

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 bFollowLocalPlayerCamera to true.

  • To use offsets in windows and viewports, make sure to set the node’s fullscreen parameter 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).
