Patreon Tutorial 34 - Part 12 - Using OSL Iridescence (Patreon)

In this tutorial I will be going over the Iridescent OSL shader. This node is a simpler version of the Thin Film Interference node but can be used to achieve a similar effect. It has fewer parameters and is a bit easier to use. It also outputs the iridescent colors based on a single layer thickness and IOR value instead of a multi-layered approach like the Thin Film Interference node. This node is also an excellent shader for getting interesting effects on materials especially pearlescent surfaces and car paints. I think a lot of people will really enjoy this using this shader to make exotic surfaces.
