Warnings are logged when entering Play Mode if Particle System is using "Sub Emitter" and having Particles System as a child

Visual Effects - Legacy


How to reproduce:
1. Open the user attached project
2. Enter Play Mode
3. Observe the Console window

Expected result: No warnings
Actual result: "Sub-emitters may not use stop actions. The Stop action will not be executed." warnings appear

Reproducible with: 2020.3.31f1, 2021.2.16f1, 2022.1.0b12, 2022.2.0b8
Coult not test with: 2019.4.36f1 (Errors after downgrade)

Note: Not reproducible if disabling child object (Particle System)

  1. Resolution Note:

    The problem is not that you've called Stop (which, as you say, you haven't, and didn't even know existed)
    A reminder of the message we are seeing:

    "Sub-emitters may not use stop actions. The Stop action will not be executed."

    The problem is that you have set a Stop Action on a Sub-Emitter. The message is telling you that this is not allowed.
    Clicking on the message highlights the systems at fault. They are called "Crackle" and "Flash". They are sub-emitters of "detonationCrackles" and use the Destroy Stop Action.

    Setting Destroy on the parent system is sufficient (which you already have done) it should destroy itself and all its sub-emitters when it's finished.
    So just set the Stop Action on those Sub-Emitters back to None and you should be good to go!
