Radial Blur

Blurs the layer in a rotational/spinning motion around a center point, simulating motion from a spinning or rotating object.

Amount controls how much rotation the blur applies.

Center X and Center Y determine where the center of rotation sits relative to the layer. You can also change this directly by dragging the Effect Point Control crosshair in the Viewport.

Samples sets the amount of repeating steps the blur uses — higher values look cleaner (better quality), lower values render faster but can show visible steps.
