    I use the control track to play particlesystems. But it can not control the particle system with sub-emitters.
    BTW, the control track also change the particle speed, not exact the same speed when I play the particle system normally.

    Did you happen to find a solution to this? I'm running into the same issue on 2018.1 - specifically, the ParticleControlPlayable is unable to correctly control particle systems that have Sub Emitters. They partially work, because some of the sub-emitter particles show up, but one of them, plus all of its own sub emitters, don't appear at all.

    I suspect there's nothing wrong with the ParticleControlPlayable itself, but that it's a problem with ParticleSystems not evaluating 100% correctly when the time on them is set directly (a long-standing issue that got much better since the introduction of Timeline, but is still not all the way there).

    Current workaround is to turn on the "Control Particles" in the control playable only while editing/previewing, and turning it off once it's ready so that it plays correctly in-game.

    Timeline not working with any kind of sub-emitor particle system at all

    I would but who will vote for that? Will it be fixed without votes? It looks like no popular issue.

    Yes, we fix bugs with no vote. The voting just helps to prioritise things.

    This thread has been driving me crazy. I invested some time to make a fresh scene with this issue for the bug report and just submitted it today. Fingers crossed that there will be a fix for this soon!!

    Important note on this workaround: Play on Awake should be on, or it won't do :p
    Any official updates on this issue?

    There is a PR pending containing a variety of fixes for Timeline/Particles that should address this. At this point it will likely appear in 2019.2.

    This is still a problem in 2019.2.21f1. We had to write our own particle player in timeline which is a bit unfortunate.
