VR injection framework for Unity -- helps you integrate VR into games that don't natively support it.
What it does
It takes care of the cameras and the GUI
It gives you a frame to work with (Controllers, Modes, etc.)
It comes with presets for standing and seated mode, plus a set of tools for your controllers
There is a bunch of helper classes, e.g. for shortcuts and for rumble
What it does not
It does not take care of the injection into the DLL itself -- use either the Illusion Plugin Architecture or Rei Patcher for this.
