Particle emitters clear emitted particles when occuleded

I believe this is intentional:

Particle simulation resets when an emitter goes out of view

Hi @Daw588, Thanks for bumping this thread and for your detailed report. Apologies for the delay in getting an official response here. We can confirm that the behavior you’re seeing – where ParticleEmitter simulations might reset when the emitter goes off-screen – is indeed a current limitation of the Roblox engine. As some users in the thread correctly pointed out, this behavior stems from performance optimizations designed to reduce the engine load by not simulating effects that aren’t curre…
