set the bounds inside cascade (reboot ue4 after you did)
I created a particle emitter to make rain and it works fine if I place it on scene. But if the player goes near they dissapear.
I want this particle emitter following the player, and sure i place it on the blueprint and link it to the camera, but it only works if i place the emiitter at some distance, if i place it above the camera as intended they dissapear.
Thnak you very much. I am still a noob and pluralsight tuts have take me so far. I fixed the bounds but didnt realize that you could customize them after restart.
so it got solved? 
yes sorry i didnt notice my email earlier. i was fighting with a masked material but I won.
I am fairly new to all this. I can’t seem to solve this issue.
I’m having the same problem - get within 1 metre of the particle system and it disappears.
I’ve tried setting the bounds to be tiny (-0.01 to 0.01) and ridiculous (-20,000 to 20,000) and in every case, the system is visible until the player gets within 1 metre of it, at which point it vanishes.
What am I missing?
You are missing the fact that you are not properly reading and paying attention

I rebooted unreal every time I made a change, still no difference. I found another way around the problem by using something else instead of a particle system, but I’d still like to see if I can figure this out - I’m sure it will come up again.
hmm only thing i can think of then is accidentally inverted min/max bounds, or accidentally created a particle LOD with nothing in it.
