I made just one immersive VR production using the games engine software Unity. It involved a lot of code, animation and took several years to complete. Originally it was intended to be a 360 degree panoramic movie projected onto a giant circular screen within which the audience could amble. It was commissioned by Tom van Vliet of the Worldwide Video Festival. Although we set it up an the Vrije Akademie in Den Haag it was never shown publicly due to financial considerations. So, I made the VR version instead using the Oculus Rift headset.
