Niagara particles collision

Hello
I am trying to create something similar to a blood splat in niagara that spawns a mesh or a decal on collision. But I don’t want it to be able to collide with it’s own particles because then it spawns the mesh in the middle of the emitter. Is there any solution to this? I also tried to follow a tutorial on how to spawn decals but seems to be outdated with unreal 5.

Thank you in advance

Niagara collisions do not generate overlap events (or at least they didn’t when I asked few months ago) so spawning decals where they hit could be difficult.

Can you please provide a better example of what you need? It’s a bit vague.

Sorry, I am quite a beginner in Unreal. But what I need is that the first mesh particles like blood spray when someone hits someone, when the particles hit the ground, I want to spawn a new mesh that looks like a pool or a stain of the previous mesh. But I don’t want the first mesh particle to collide and spawn the stain on its own particles nor any moving object. Just the floor.
