Anisotropic reflections

Hi all

I'm trying to create vinyl material inside octane and haven't succeed yet
In octane is no anisotropy parameter in material section and only one way I found on the Internet - use bump
So I tried and faced an issue, anisotropic reflection appears only when bump is really strong and surface look really scratchy. When I'm reducing bump amount - anisotropic effect starts to disappear

Is there a way to create this kind of reflections and not have so scratched surface and mimic vinyl material?

Cheers

Hi SergKlyosov,
try to edit specular and Roughness,
however texture also affects the final render.

Hi Paride,

Thank you for reply

But on your render example - there is also a really strong bump and really deep carved lines and it doesn't look like vinyl with just a tiny scratches
For example there is a way to achieve it in corona renderer, where you can put angle gradient in the anisotropic angle slot and it gives you proper anisotropic reflection without any bump

Can we do something similar in octane? Or this feature will be introduced in 3.08 with new metal shader?

Hi SergKlysow,
yes, anisitropic will be introduced in 3.08, but with good bump or normal textures you can achieve good results, working with gamma and contrast.

Hi Paride,

Can you please tell me how can I create this angled gradient type for anisotropy rotation map using Octane nodes, but not for multiple circles, I want create only one?

Thank you
