New update today!
You can now rebind your controls from within the game!
Please note that the control binding menu system only works in Non-VR mode, but once you've configured your controls then they will be used next time you start in VR.
I have setup the default controls to work with an XBox 360 pad...
Throttle = Triggers
Steering = Left Stick
View Control = Right Stick
MFD Control = D-Pad
Engine Toggle = A
Anchor Toggle = B
But you'll probably want to change those to something you prefer.
Binding controls doesn't effect your VR virtual controls or the controls bound to your VR hand controllers. Changing the VR controller bindings is still done via SteamVR's control binding interface.
