    Hi,
    I wonder if there is a way to make the particles not disappear immediately when the bounds disappear from our field of view? So that the ones already generated don't disappear so suddenly.

    Regards

    Probably no (or rather not in the way you want), this is the whole point of bounds to work this way. They are not used to fade particles, but determine if effect is visible at all. In short the intended use is to cull the vfx completely when all particles are not visible, not just 30% of effect.

    Hi,

    The first thing you should try is to make sure that the Bounds are correct, and even maybe to make them bigger for safety.

    But if you really want your VFX to be updated, you could check the culling flags in the Visual Effect Asset:

    This will update your particles even when they are not visible (with some performance cost, of course). Use it only for rare cases :)
