Patreon Tutorial #34 - Part 11 - Using OSL - ThinFilmInterference (Patreon)

Hey guys, in this tutorial I will be going over the Thin Film Interference node. This node is a bit more complex than the iridescent OSL node but functions in a similar fashion. This node allows you to make iridescent colors using several complex parameters that control the thin film thickness and IOR values for 3 different layers. A top layer, a mid layer and the base layer. This can be used to great effect for some interesting material shading. The node has a lot to offer and can be a bit intimidating but it is one of my favorite OSL nodes.
