This page includes information about smaller features of the VRGK.
A simple Subtitle System is included if you have any Voices in your game. You can show and hide the Subtitles by calling the Global Function "Get VR Subtitles".
The BPC_CollisionSound Component can generate Sounds on Hit Events of Actors. Your Primitive Components (Static Meshes) need to have "Simulation Generates Hit Events" enabled for this to work.
