    Hi,
    Is there any way to have a sub emitter the way Shuriken was doing it? For example, when a particle dies, spawn spawn an effect there or an emitter that follows a particle's position?

    thanks!

    Hi @Phantom_X ,

    Yes! You will first need to enable the experimental operators/blocks:

    Then you can add a trigger block in Update, connect it to a GPU event, and inherit any parameters you want in the new "sub emitter" system. Here is an example:

    And of course make sure the sub emitter system has a large enough capacity to accommodate the number of particles you are sending from the parent system, otherwise you won't see all the particles.

    Hope this helps!

    Hey,
    Thanks for the example, definitely helped!

    I also wanted the sub particles to follow the main particle so it would leave some kind of trail.
    Taking your example I changed the trigger event on Die to a Trigger Event Rate (Over Time) to achieve the effect I was looking for.
