I created a particle system. When the box size is too large, moving the angle of view in the editing interface will make my particle system invisible, but it is completely invisible when the game is running. How should I solve it

Hey there @Dusnowbychen! I need a bit more information to help you out!

What type of particle system are you using? Cascade or Niagara?

May we see an example of it occurring?

May we see the setup for the particle?

Feel free to take a look at this thread to see if some of these fixes helped in the mean time, and let me know!

> Hello thank you so much in advance, I have a problem with the particles, the particles are formed by GPU types, normal and Mesh. The particles disappear at some camera angles, but in editor mode they work great. I’m trying to simulate the rain, and through the event of the particles, I instantiate the splash effect mesh. But I’m experiencing the problem with the third-person character room. There are / there are settings that I should set. Sorry for my bad English. Thanks again.
