I haven’t been able to find the more advanced version that vanished. I found out that you can get their limited pool of gestures working by adding a “Leap” controller to the actor that will use the gestures. This must be added via components pane in the top left hand corner though, and cannot be done through BP anymore. Then, with it added, you can select it, and some events will appear in the details pane that you can add. It’s extremely counter intuitive to how it used to be, but it works to a basic extent.
