This scene had to be optimized to run on hardware ranging from the iPhone 6s up to the new Mac Computers with screen resolutions over 4K!
To pull it off, the scene uses one piece of geometry instanced 500 times, and a single UNLIT Shader creating the illusion of shading an depth based on an input vector simulating the light direction, and falloff based on the distance from each surface to the main camera.
Additionally, the surfaces are reacting in real-time to audio input coming from Audiokinetic Wwise.
The scene is actually a perfectly straight cylinder. The illusion of the perspective collapsing, the tunnel turning, and twisting are all created in the single UNLIT Shader applied to all the geometry.
