MouseWheel Axis mapping missing

At the moment it’s only possible to act on whether the mouse wheel is spinned or not. This looks ugly, for a nice smooth usage of the mouse wheel we need to know the delta how much the mouse wheel was actually spinned since the last frame. So please fix the mouse wheel axis mapping. It’s actually possible to select MouseWheelUp and MouseWheelDown as an Axis mapping event, but it always return 0.

Hi John Alcatraz,

I was able to reproduce this and have entered a bug report, UE-12863 to be assessed by the development staff.
