I am trying to make a gear material where there are highlights that are like lines facing outward from the gear's center. This image shows what I am trying to accomplish. How can such an effect be done?
Thanks in advance!

Here I'm converting Generated Coordinates to something like Object Coordinates so this should work on any size of gear.
A Gradient Texture set to Radial gives us this output.
If we feed this into a Noise Texture we get this.
We can mix in a bit of the regular coordinate space to give some irregularity.
And here I've used this output to drive the base color between two shades of brown, the roughness, and a Bump Node. I've also used a bit of regular ol' anisotropy.
And since these are generated coordinates based on a bounding box around your mesh, you can easily use this on any size of gear.
