Recreating a zig-zag lines migraine aura

Hi,

I am working on a small demo to demonstrate the visions of a migraine with an aura and I am curious how I can start to recreate zig-zag lines experienced as part of a migraine aura phenomenon. I added the image from wikipedia as an example:

How can I implement such an effect that is constantly visible on the screen? Another consideration would be that this effect gets bigger/smaller and moves.

Thank you in advance!

Hello,

My first thought is to use a Niagara particle effect system with a ‘Ribbon’ emitter.

I think the big question would be whether to use a ‘zig zag’ texture/material or to try and add ‘noise’ to the ribbon points to make it spiky. (or maybe a little bit of both)

I’d say level up your knowledge on creating ribbon emitters and go from there! Let us know how it goes!

Thank you. I will try that out! :slight_smile:
