SUNROCK: SteamVR Knuckles Support for UE4

If you re-bind the default bindings in steamVR itself and replace them it won’t generate them every time…and you can define custom events in engine that are used.

1. If UE4 SteamVR plugin generated binding and actions manifest files, it would re-associate UE4Editor with actual inputs every time you open a project. Binding files are only geenrated in editor. For packaged game, user can overwrite them via standard SteamVR interface.

2. I want VR input in my project working regardless of hardware I use. For Vive controllers, Knuckles, Touch via SteamVR, Touch via Oculus API.

Example: I use touchpad for locomotion input. But touchpad on Knuckles isn’t good for this purpose, because it has very limited X axis. Instead, I have to use joystick. So I need custom binding files to bind Vive/touchpad and Knuckles/thumbstick to the same action, because I can’t separate touchpad at Knuckles from touchpad at Vive controllers in my player controller blueprint. And even if I could - it’s unnecessary duplication of work instead of unification.

@mordentral

The pre-filling of the bindings and hard coding of new events is actually somewhat counter productive

Oculus has no similar input system, it uses default UE4 events for motion controllers. And I don’t understand how you’re going to build unified input system without using unified input events/axes.
