So I got this project where interactive demo is launched on a 42" LED screen with surface light wave multi-touch sensor powered by Win 8.1 gaming PC. Now, Windows recognises the sensor panel as a multi-touch device, then I make use of virtual on-screen joysticks provided by UE4, but I don’t have multi-touch capabilities in UE4 project – while using one joystick, the second one is non-responsive.
What I’m doing wrong?
