Particle Culling?

Hmm I’ll have to take a look into that. Before I start though will this be a hard snap on/off or a somewhat softer fade in/out like I wanted. I’ve yet to really dig deep/mess around with LODs, my apologies for my noobishness lol. I wanted to use this culling to help with my rain setup that I want to try out.

Around the level I would place my Rain emitter in a grid like fashion, then using the distance culling, it would only render the rain in your immediate area. But as you moved closer to the other emitters they would be raining as well.

TL : DR
I wanted to make it so only the Rain Particle systems in the players general area were rendered so the performance isn’t completely flat lined by having every Rain system going off at once. So does this still sound feasible if I go by LOD to accomplish this?
