I'm new to Nodes, trying to archive brushed disc effect with the node editor, ad anisotropic node but it's looking poor can anyone please help me with this. Any suggestion? I also created bump node looked for the procedural texture 'Radial' each time it's crashes lightwave.

i think you can modulate using a grey scale map with enough contrast connected in the specular input(anisotropic spec shader), and maybe add an extra touch with the old trick for reflections , a big riple with a big scale turbulance with low frecuencies and low small scale in the bump channel.Another alternative its improve the enviroment and lighting.

Thank you lightmann, for your tips. I'll try do it right now, but have no idea how to make ripple or turbulence behave in circular fashion. I can make linear brushed material, but wondering how to archive circular scratches.

Set Ripples to 1 Wavesource.

Thank you dee, I never was able to archive this effect even in v 7.0 days with BDRF shader. No with nodes I more confused, I better look for some basic lessons and training videos. Thank you for input.

There's a really good nodal Anisotropy tut here:
