I’m a Blender user that is using 2 curves to animate a nerve impulse.
The first curve represents the nerve and has a fixed shader material.
The second curve is a animated to appear and disappear incrementally, with an emission shader. It produces an effect like this: password unity
You could replace the particle in blender with a dummy object, animate that around the same way, and in unity, when you import the animation, you place a unity particle system into the hierarchy of the animated dummy and recreate the effect in that.
I don’t think you can import a particle system in it’s entirety into Unity afaik, you have to create the system in unity using their Shuriken particle system.
