How do I activate my VFX?

[Wezo (Wézo)]

Hi, I migrated a Niagara System into my map and I’m still a noob in UEFN and I would like to know how to I use a button or an alteration zone to activate/desactivate the VFX? Bcs all I see is activate automatically but I do want it to start when I interact with a button or go into an alteration zone.

Hi Wezo,

Mmmmm Banana and Goose smoothie - yum.

Try adding your VFX to a ‘VFX Spawner’ device. (Set as “Custom Visual Effect”)

You could then connect it to the Mutator Volume with the built-in hooks/functions.

I tried, but it wasn’t shown in the game.

I figured out how to place them.

1. Double-click on them in the content tab

2. Click on the red and click “solve problem” to make it usable

The unsolved problem is that I don’t know how to trigger a button or anything else to make the VFX (N.S.) show/disappear.

In fact it is a playroom but this banana-duck is very weird.

It is stocked in a blender and do a Quack sound and a music when someone press the button.

I try to add a space explosion VFX to make it even weirder but funnier.

Hi again,

I just did a quick test and was able to trigger a ‘Custom’ VFX with a button:

I changed ‘Enabled on Phase’ to None to make sure that it did not start playing when the level loaded. Then I hooked up the VFX Spawners ‘Enable’ function to a button.

OHHHHHH I just understood why! It’s because I had to

1. Double-click on them in the content tab
2. Click on the red and click “solve problem” to make it usable

and THEN use it with the VFX spawner.

THX @Astrotronic!!! It’s going to be WAYYYYYYY easier for me to use N.S.!!
