I’ve noticed that whenver the particle system actor (as in, the root of the particle system) is not within the camera view, GPU particles dissappear instantly. This is a huge problem for me, as I’m using them to generate bubbles underwater from a waterfall.
As soon as I look down the stream, the bubbles dissappear, even if they are within my view. Is there anyway to stop this behaviour?
You need to increase the bounds of the particle system.
Thanks! That worked, and also encouraged me to learn about Occlusion Culling
How do you do that? I’m having the same issue, but cannot find a way to increase the bounds. I also cannot find anything about this on the web.
When in Cascade, click on the background (black area) to get the properties for the emitter, and you can set the bounds there.
Thanks, but this seems to not work on 4.16+. Any other solution to this? im going nuts trying to figure this out.
“Set fixed bounds” fixed it for me on 4.18.3.
It’s in the upper row of symbols within the particle editor, the 8th symbol from the left (bounds). Simply click on the arrow next to the symbol, it’s the only option then.

This worked for me. Thanks!
