Extend lifespan and stream time - PortableAnswers - 22-05-2026
Hello, from what I've experimented with, it's a trade off between lifespan and the stream time. For instance, if my lifespan is 5 seconds then I can only have a stream for a few seconds until it stops and I must wait while the spawned fluid despawns. Am I understanding this correctly and is there a way to keep the stream going regardless of the life span? Thank you!

Hi!
There’s no tradeoff, you can keep emitting particles regardless of your particle lifespan. Just make sure you have enough particles to emit, like in any particle system (Unity’s Shuriken and VFX graph work the same way).
In Obi the amount of particles is controlled by setting the blueprint’s *capacity*:

Needless to say, the more particles you’re simulating the costlier the simulation becomes.
Kind regards,
