I managed to get the Oculus Rift virtual reality goggles work with Clinically Dead. The results are great. Immodestly, I have to say that Clinically Dead is one of the best VR experiences I ever had. I also shared my implementation code on Urho3D forums. For now as plain code and instructions, but maybe in the future I will make some pull request to the official Urho3D repository. Stay tuned and in the meantime, I will work some more on the game.
