Irridescent Glass Shader

[Unknown3dartist]

Hello there, I would like to achieve the result below in Blender.
I tried already, I achieved some purely glass or irridescent but I just would like subtle touches/ reflections of irridescence.

So if you have any tips I’d be glad, may thanks !

Real irridescence material is complex. For this you can use VSHADE addon.

GPU Compatible Thin-Film Interference v2.1: Glass Within Glass + Absorption

Update Pending: See post 72 for update v2.2 Hey everyone! Welcome to the colorful update of v2.1 of the thin-film interference node group which was originally adapted from @prutser’s OSL code. Here is pruster’s original thread. This new update generalizes Snell’s law for lossy incident media (such that R+T is always 1 when the films are not lossy), adds absorption, and allows the dielectric inputs and outputs to be calculated with RGB values like everything else. Only the “Interference”/“Thi…

Micro/angle dependent Roughness & Iridescence

How about a different approach. In this case - I created 3 colour ramps (R, G and B) based on this graph from the link below [image] [image] http://markkness.net/colorpy/ColorPy.html I then added them together using the layer weight node key the observed thickness as a function of viewing angle. I wonder if it might be possible to recreate the graph using a simple math function for each RGB component, rather than using colour ramps. The three RGB components appear to be based on a sine w…
