Name of a effect

I’m looking for a effect, which I have used before in Garry’s Mod. But I, for the live of me, can’t find it anymore!

I do know that effect is being used in gm_finaldestination from the workshop. I want to know the name of that effect.

Is there a way to find out, in Hammer or another program, which effects are being used on that map?

If it is a .pcf effect, you can find it’s name by using a console variable that shows all active effects on the map.
