Overview
What RadialBlur does
Creates rotational motion blur around a configurable center with realistic/stylized modes, symmetry direction and quality controls.
Center Position is the visual anchor of RadialBlur: the same blur strength can read as spin, zoom or off-axis motion depending on where that center sits. Blur Type and Symmetry then determine whether the motion feels natural, graphic, clockwise or counter-clockwise.
Use channel adjustments and quality controls only after the motion itself is right. At strong settings, Border Type becomes important because radial sampling easily reaches outside the frame and can reveal black edges or unexpected wraparound.
Mental model
Picture the image rotating around a pivot during exposure. Pixels smear along arcs centered on the chosen position rather than along straight lines.
Common uses
Create spinning motion
Add radial speed energy
Build vortex-like transitions
Blur rotating graphics
Create stylized circular streaks
