Pepergogo:

Hi
I'm using M.A.K.E C E N T S soulboxes in my map and I want to add an fx to you can find the box, but I want the fx disappear when the box is fill. Here's the name of the fx: "fx_vulture_aid_powerup_glow_blue".
I tried to do it but the fx is still there all time. I know I have to put also something in my zone file but I don't really know what and how :(
Does anyone know how to do it? Any help is really appreciated

Yeah, I have a door in the reward
But the fx I'm using only to show where the soulboxes are in the map
