special effect help

how do i make a special effect on a unit(about 8 of them). i want just the effect, not the unit, so when i try to do the trigger creat special effect in region or sumthin, in made the special effect for like 1 or 2 seconds. so then i tryed making a unit and having it inbisable, but that didnt work, the special effect became invisable with it, so then i tryed making the unit's scaling value to 0.1, but now the special effect is the size of the unit. i want the special effect to last the whole game. so how do i do this?

What special effect are you tring to use? Some effects like MassTeleport only last for a few seconds.

o sry i guess it will help to know wut effect it is, its Abilities\Spells\Demon\ReviveDemon\ReviveDemon.mdx

the demon revive

Because that effect only last for a few seconds and doesn't repeat you will have to make a trigger that destroys the last one you created and creates a new one at that point again, every so many seconds (peroidic event). If you don't destroy the last one you created it could produce a slight lighting error.

You have to refresh the animation, time how long the sfx lasts, then create a period event that destroys the sfx and recreates it instantly, it might look strange because the beginning frame and the last frame arent meant to overlap.

ok ill try to do that.
