I have a particle system that uses a character mesh, I want to call it when the character enters a trigger, but I don’t understand how. This only happened if I use onBenginOverlap with the capsule component, but then it reacts to all triggers, and I only need a specific one. Can anyone understand how to implement this? Thanks.

You just need some conditions. For instance, you can add an Actor Tag to the trigger and check it:

Or you can let the trigger handle it. Just create a custom event in the character blueprint that will activate the particle system, and create an overlap event in the level BP:

Since I’m a beginner, I did it as in the screenshots and it worked, although I did not understand why. Thanks

The Cast node is checking if the object that overlaps the trigger is the character or not, and if it is, it tells the character to execute a function.
