Who worked closely with the metals - tell me how must be formed of a material that would achieve the correct effect of anisotropy . Thank you

Please read this and try second bump map like in my very bad tryout bump image. At least should give a idea to distribute direction of reflections. Hope this helps

I have exactly the same raster map for Bump strips diverging in a circle. But my aim is more difficult if I have animation. .... I need a physically correct material. I'll test the textures. Maybe they will help me from your lesson

I think you have to use the map displays with maximum quality 8000x8000 pixels then it will be possible anisotropy of the physically correct.... tomorrow will hold the test

I think a Normal map would help you further.

anisotropy obtained only a procedural map bitmap should be prepared by another method evidently it must be prepared using Illustrator with a uniform spacing of the rings

the bump map (12000x12000pix) does not allow for anisotropy ,....

i made a quick test-file:
The bump maps have to be very low...

download the radial brush texture here:

Yes thank you makes texture anisotropy but not so pronounced as procedural map of the noise - making piece of video

The texture you need to cook :)
........... But still I like the noise procedural map
