Make conical gradient
Don't tell me abous mesh trick, it has it's limits and surely is not that easy to use.
Just make Conical type gradient from the box.

Please. This. Yes.
I'm trying to make a gear for example. I want it to have a hollow center, and have a metallic sheen. Neither linear nor radial gradient fills will give me the effect I'm looking for. I have to create a circle, fill the stroke with the gradient, increase the stroke size, and outline stroke. But I can't subtract a shape from the circle, so I have to create the gear as a separate object and make it a clipping mask for the underlying circle.
