Spline + Particles + Overlap

Hello!

Is it possible to create a spline blueprint that uses particles instead of meshes?

Furthermore, is it possible to set it up so that when the player overlaps a section of it, that section disappears?

Any idea on how I could get started on this? I’m trying to do a navigation system that’s a part of my game’s world and I’m exploring options on how to make it possible without placing each particle in a blueprint on the map. I want to try and make it dynamic with the ability to guide the player. Something similar to Fable!
