Merging reality and VR.
RealityBlender allows you to see your surroundings on a 2D overlay inside your VR headset!
Use camera feeds and Chroma key to blend your surrounding environment into VR and create a mixed reality allowing you to enjoy the best of both worlds. Perfect for cockpit based games such a space, racing, and flight simulation where VR has greatly increased immersion at the expense of seeing your cockpit and controls.
Currently in Early Access Reality Blender is only compatible with games while run in SteamVR/OpenVR mode.
