Is it possible to draw a running windows apps GUI window inside of Unreal and where would I start? Is it a windows API thing?
Its for placing an existings app in a VR environment. For Unity I found this, Has this been done in C++ for Unreal before?
That Unity solution basically keys out part of the image to show your desktop underneath, that wouldn’t work for VR. Otherwise, there’s not going to be a way to display a Windows window in UE4, you might be able to create a custom UI to do the functions that you need though.
