Blur Toolkit URP is the new best blur package for Unity.
It Integrates all Blur algorithms you need, including Gaussian, Radial, Mips, and a self invented Fuzzy Blur!
Fuzzy blur randomly offsets each pixel, making a noisy blur. Because this can happen in just 1 iteration, this is blazingly fast while being flexible.
You can blur textures, scene color/opaque texture on 3D objects, full screen effects, and even UI with Unity 2023.2+/Unity 6!
All methods are easily tunable with the included shaders, materials, and scenes.
