Apparently there is no good way to interact with 3D UMG widgets in UE4 using so called gaze controls (tracing from view, hitting 3D widget, etc.).
Dear Epic, could you please fix that and add functionality so that gaze interaction with 3D UMG widgets could be easily utilized in VR and non-VR projects using Blueprints ? (and also ability to set custom cursors and keep those confined to 3D widget)
P.S. Not just for PC, but for Android / Gear VR
