The video that you see is a VR scene treated like a video, as Olivers described it.
For lighting, he wanted to achieve a nice-looking refracted neon light that wouldn't cost much of performance. So, he created a simple simulating shader for neon light refraction.
When talking about making VR, Olivers shared some detail of it: "Some film effects won't be there in VR.. as you don't want motion blur, grain, cinematographic color correction or DOF in VR. I look at this as a filmmaker would look at VR. Instead of taking a real camera to real place and filming, I'm using Deckard and virtual camera to film VR. Different media require a different approach."
