Hi!

Sorry for my level of english, first at all. I'm new here, and with Octane also hehe. I'm Lucia. (Spain). Nice to meet you!

I'd like to ask you for a question that I have. I can't get this Iridescent material. It's georgeus! Do you find this artist as @Catelloo in Instagram.
Do you know how can I get this similar material? The reflection is cause the lights? The material..?

Being new to Octane too, I’m not sure I can be a great help here,
but my guess is this kind of effect could be obtained by tweaking the film width and film index channels.
Sirely some pros around can give proper suggestions.
(I’m also interested in reproducing iridescent materials for my mineral reign library).

Yes correct, for this kind of effect you need to play with Film Width and Film index.
Here is an example by adding a noise texture to the Film Width pin:

Change the Film Index to change the spectral variance.

Thanks Bepe you're always a great help !
I'll try to use this on my Mineral library too ;) ...
I guess mixing it with falloff and other effects allows to obtains the various effects we find in nature...
This opens perspectives ;) ...

Thanks for the encouragements Bepe !
My idea for using the iridescent effect was mainly for minerals materials like Labradorite and quartzite...
But i didn't dare getting much into this kind yet , and stayed with the classic not transparent and whithout much special effects yet...
It's going to be a hard process I guess...
