Distortion effect on Particles?

I wish to make a effect similar to this :

The sword slash effect which creates a distortion trail between 10s to 15s of the video.

Back in UDK - it was a simple Distortion shader with animated normal maps.

Any leads?

You just need to add a Particle System with that kind of material attached to them.

Check the Asset Store > Textures & Materials > Shaders.

Or you can use Strumpy Shader Editor to make one - Strumpy Shader Editor | Visual Scripting | Unity Asset Store
