Particles outline

Hi!

I’m trying to create an outline around the particles in my particle system, I’m a bit stuck where to begin.

The tutorials I’ve found are mostly around outlining 3d meshes, or individual sprites, rather than a batch of particles.

Heres the affect I’m trying to achieve:

Ideally, I’d also like to use shader graph to achieve this rather than writing the shader by hand.

Anyone know where to start with this?

You have two choices and a crappy third.

  1. Build a metaball shader with post effects.
  2. Create an unlit shader with a simple outline.
  3. create a plane between the camera and the particles to do a localized post process.
