How do I get my custom rain particles to work?

When I made a custom rain particle for my game, I put the particle into the world but it did not show up. only the particle symbol was there but no rain. How do I fix this?

What your editor escalability settings? Do you use in production mode? Material quality is set to high? You particle bounds are reponsive? Check this options, maybe can be one of this. I’m not a expert in particle system, but i have a similar problems with this and i solve adjusting particle bounds. I hope that this usefull.

Where can I find the material quality, know when I’m in production mode, and where can I find the particle bound? (I just started using Unreal so… I’m not that experienced in anything).
