Absolutely, this video reveal all the secrets of anisotropy, thank you for this link.

Polygon Division goes in depth about the subject too.

@Dr-Sassi

Thank you for your advices. It helped me to find a way to nicely represent this anodized metal and brush it acurately.
Here is the result I got.

I'd like to reproduce this type of metal.
We can see the anysotropy specular effect is tinted in blue on the circular brushed blue material.

Dear Dr Sassi,

There is something I don't understand with the new standard material on Redshift. I have a metal material, I want to tint it in let's say green. Ok, I put the green color under color, then the full metalness to make it nicely shiny. Here is my problem: in various anodized metals, the color of the specular could be different to white, like let's say a blue spec, or any other color. With that setup, I struggle to change it the way I want.

The only solution to colour the spec would be to remove the metalness and increase the IOR value to get close to metal, but then the diffuse color and the specular color are overlapping, that sounds kind of wrong to me..

I'm pretty sure I missed something, but I couldn't find any information so far about this specific question.

Thank you, I hope it makes sense..

Thank you for this very valuable help. Deforming the geo instead of using a texture image is something I didn't even think..
It does a pretty good job and the light deformation appears to be more conform to the reality.

Here is the result I get. Much better.

Once in context

Hi Dr Sassi!

I'd like to reproduce this effect:

I'm quite close with this:

I'm not so sure about the spiral effect in the anisotropy, maybe there is a better way to do it. Thank you for your guidance.

Cheers,

@Dr-Sassi
That's great!

I worked on it a bit and I can say now I exactly get what I was expected.
It's very close to my reference and I can make various type of metal chips based on that idea.
I'll do the other type of metal chips, the ones on the left of the video now.
I'll come back if I have some questions.

Thank you again for your help, this is exactly the type of messy metal chips I was looking for!

Dear Dr. Sassi,

Thank you for taking time to build this example. It's interesting and that could be an option.
I found an other way, probably closer to the reference.
I get only one problem, the head of my string is not looking good (it looks like it contains the the rest of the helix that didn't travel yet on the path), I was wondering if you know a way to fix that?

metal_chip_WIP.c4d

Hi there,

For a client I'll have to reproduce that (sec. 11 on the video).

What will be the best approach to achieve those long metal chips coming out of the metal bare?

Thank you for your inputs.

Cheers,
Arnaud
