Attaching a particle emitter instead of a texture material

So I’m trying to make a particle emitter movie down a mesh and make the material follow, I’m really looking for the easiest way. In the picture you’ll see the cubes have a blue colour that moves up/down the material. I was hoping someone could tell me how I can make the green particle effect replace that blue line? Sorry if it’s badly explained I’m quite new to UE4.

Any help appreciated, thanks

Hmm hello Kyt,
I dont think there is an easy solution for this.
What I would do is make a thin high poly skeletal mesh that moves along the erosive/blue line.
This is because you can attach particles to the surface/vertices of a skeletal mesh with the “skel vert/surf location” module inside cascade.

IF you make the skeletal mesh line move along with the blue erosive line, it should look very decent.

I hope this guides you a little towards the right goal.
