    With GPU events, its great to be able to spawn secondary particles that inherit attributes of the source particles (e.g. current position).

    Currently, those triggers can be fired:
    • on death of the source particle
    • over time of the source particle
    • over distance of the source particle
    I'm looking for a way to control that trigger point via script that modifies the vfxattribute with some kind of signal

    Any ideas?

    For context, imagine a main vfxgraph that is simulating a jump rope, the source particles live forever, and their position is animated over time. I want to hit the A button, and make the rope emit secondary GPU particles from the current position of the rope.

    Hi. You can plug an exposed property into the Trigger blocks and set it to 0 when you don't want to emit events
