Hi, When using a Touch Screen in Windows (a secondary one set up next to my main screen), I get this strange behavior: Play in PIE mode (on the Touch screen): Unreal interprets the very first touch and 3 frames of finger movement as touch, then switches to interpreting Touch events as Mouse event…

Okay, so here’s a partial answer after some more investigation: Touch does work in PIE when all displays except the touch display are disconnected (but you have to restart UE4 to get it to work). So a single screen setup works. If, like me, you really want to work on one display and test touch…
