Radial brushed metal pattern?

[Kinetic99]

Hello and thanks for your time,

I've tried using bump or normal maps of radial lines emanating from the center and out but I get too many artifacts and moiré patterns.

Would you know if a way to create a brushed metal look so that it starts from a center and radiates outward.?
The goal is to get this look but not deal with shimmering and moire.

yep! That's what anisotropic reflection is for. spiral gradiant ramp in the rotation slot does the job.

Just for accuracy's sake, I wrote a tutorial on the subject back in 2002...
