Great Plugin if it really is fast.
Just adding one more usage for it:
1:1 texture (or material) for touch interface. Default touch interface in unreal has trouble when you
slide touch point outside widget, it keeps testing as widget is touched.
With this just paint what is where in texture (can use render to texture, to paint it at begin play depending on resolution and device/layout), then use this plugin to detect if user is actually touching widgets.
Well replace whole messy widget touch stuff with simple code that detects what was touched (using this plugin), then fire events.
