Particle can be seen on Editor viewports but not in GAME

Hi, the particle system works fine and is visible on view port but in game can’t be seen.
I have Two sided material apply.

Can you show the particle ingame and the cascade setup of it?
Did you turn on realtime?
Are they gpu particles? if so did you send the bounding box?

ok I will.
I let you know.

Problem solved, I have created a blueprint and then it work.
