Particle amount is different in-game

Hi guys, Im totally new to UE4.
when I try to spawn some particle in the level, it works fine in the viewport mode
but when I hit Play, the amount of particles decrease a lot.

hope someone can answer this, thanks a lot!

this is what it shows in the viewport as I desire

this what in-game

either your engine settings are lower on play, or you have LOD’s set up for your particle effect.

its the LOD issue. :slight_smile:
