change the center point for anisotropic material

[acaelus]

Im working on some artwork for a watch I am going to have made and i need some advice on how to make the sub-dial anisotropic material centered on the sub dial and not the whole object.

Thanks in advance!

You can add an empty at the centre of the subdial and then use it as the tangent coordinate
