How can I make a ring-shaped ribbon?

I want to create a showave-esque/circle effect using Niagara’s ribbon renderer. Is it possible to do this in a somewhat simple way?
Shockwave

If I understand correctly what you want to do, probably easiest way is to:

  1. Draw a circle
  2. Make it grow with time
  3. If you want it to have a bit distorted shape then you add distortion texture to it.

other way

  1. Make a disc mesh
  2. Make a texture with horizontal line
  3. Make disc grow
  4. Distort with texture

Also you can use shader to pass groving radius value and compare it with UV coords and cut unwanted area with step func

I’m trying to achieve a circle effect using ribbons, not textures or meshes

You can spawn particles in a circular arrangement and set ribbon renderer.

Whenever I do this, It just creates an entanglement of ribbons

you have to set Ribbonlinkorder in an ascending order (ie UniqueID or ExecIndex).
