Overview

What VariBlur does

Varies blur strength across the image from a selected channel or map, with multiple blur methods, quality, size and limit controls.

Blur Channel chooses the map that varies blur across the frame, while Method selects the character of the blur. Alpha and Luma are useful for masks and depth-like control; None reduces the setup toward a conventional uniform blur.

Blur Size sets the base amount and Blur Limit caps extreme values from the control map. Build and inspect the map as a separate branch when possible—many VariBlur artifacts come from a noisy or hard-edged map rather than from the blur algorithm itself.

When to use it

Blur a background from an alpha map
Create soft transitions across graphics
Build depth-like selective blur
Smooth only chosen luminance regions
Use procedural maps to animate blur
