Hi,

I want my particles to be active in eg. 4-12 seconds of the animatic. I added my particles track to matinee. But somehow they cannot turn off. They are emitting all the time, no matter what keys i make

Hey MegaJuzwa -

First I want to make sure that your particle system in the level is not set to “Auto-Activate,” check in your system’s detail panel and ensure that the check box next to “Auto-Activate” is empty.

Next make sure that your matinee actor in your level is told to play when you are running the level. This can be done one of two ways. The first, and this assumes you want the matinee to start as soon as your level does and continue looping indefinitely. For this method, go into the details panel for your matinee actor and check the click box next to “Play Level on Load” and, assuming you want it to loop check the click box next to “Looping.” This should now play you matinee actor in the level and trigger you particles as you planned out.

The second way assumes you do not want the matinee to begin at level load, but want to trigger it through a trigger or scripted event. For this we are going to use the level blueprint to trigger a Play node attached to your matinee actor from an event, or trigger.

Let me know if you are still having a problem

Hi,

Thank you, auto-activate helped and it works :slight_smile:

But about the second way. I also tried to activate particles in level blueprint by trigger volume - OnActorBeginOverlap.

And it works as long as the trigger actor is a player. What if I want to change an activating actor? eg my flying ship, that goes through trigger volume?

That is a setting on the Trigger itself as to what counts as a hit or not.
