Hi,
Can anyone help me out with creating "fish scales" effects?
Something like this:

Just set up a regular metallic shader, with anisotropy and use something like the attached map in the anisotropic rottation slot.
Lai veicas!

Cool! Can you suggest where to find such maps? I got through all google, but couldn't find. Maybe I am using wrong keywords.

Make one in photoshop!
Takes like 5 minutes:
Start with square canvas, turn on grid and draw an angle gradient from center outwards. Then using round selection tool copy a circle.
Now you have a basic building block, just tile these circles however you want them and that's it.
When loading the map in vray, use gamma 1.0 instead of 2.2 for the texture.Comment

Thanks again. Will try it.Comment

Ok, I made map, but I am doing something wrong, because I can't get result I need - it renders just as simple metal without pattern.
Could you please sen me screenshot of your parameters?Comment

Sorry, got some renders going on at the moment.
Key points to make it work:
-Lower reflection glossiness, something like 0.65~0.85
-Set the anisotropy amount to 0.5~0.9 (or try the same numbers but with negative values if it looks weird)Comment

This is the best result, what I get:
It's still isn't what I need.Comment

Yea, that doesn't look exactly right for some reason.
What's up with the lighting in that scene? It looks just flat white light from all directions. This kind of setup really is not a good way to evaluate metallic shaders, you need some contrast- black/dark environment with brighter/smaller lights. Even if you need to show the final product on white, you should use some sort of reflection override or an invisible hdri to get a decent result.
Can you show me how it looks with better lighting?Comment

I am using HDRI studio light. I changed render view a little bit. Now it shines a bit more, but still - result is weird.

It looks like the anisotropy is incorrect - the shine should come from center outward, while yours seems even and at an angle.
Can you give it a try with the map I posted earlier?

If it still looks wrong, maybe try changing the anisotropy axis (x y z)
Your goal is to get the reflections that look like hundreds of tiled pot lids

Yes, that was the problem. I made linear map, instead of radial. That's why it looks weird. Now it looks as I need:
Thank you very much!
