Help making a nebula particle system

Hey so I’ve been experimenting trying to make a good nebula particle system for my game but I’ve been struggling to get the effect I would like. This is my attempt so far using particle system with a nebula cloud sprite, it moves around a little bit too:


But I want the particle system to be more wispy-like; instead of trying to describe it this is an example for what I would like (sorry if it is a little fast):


I’m not sure if this effect requires some shader graph stuff either.
Can someone please help me out, thank you.

Hi ! You can use a flipbook with a looping animated wispy smoke baked in for your particles.
Unity provides some free for use looping flipbooks that you can find here: Free VFX image sequences and flipbooks
Hope this helps
