How to make niagara particles to pile up?

[ha.jung]

Hello,

I’m using unreal 5.2.
I’m trying to make a scene where the particle piles up in the cylinder.
Particle’s life is forever.

No matter how big I make the sprite, it doesn’t pile up, just stays flat.

Is there a way to adjust the size of particle collision?

Thanks
