Hello

Certainly simple when you know it but this is not my case
How could you do it ?

Hi,

if you want create realistic and physically correct, it is not simple. You can use VSHADE add-on.

But if you want only create artistic view, then simply:

Take a look at these threads:

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…

A complex approach - Iridescence in cycles

I was wandering today on how to make a more accurate iridescence effect. I know that using the layer weight and a rainbow ramp can produce some acceptable look, but not quite accurate. The big problem, is that cycles will color all the scattered rays with the same color at the point being rendered and not each ray by their own direction. So i was thinking how to overcome this, and have something more real. And then i remembered that the samples for each pixel don’t hit everytime in the same pr…
