i want to make a fog effect, kinda like the map hacks , like the grey fog is there(were youve been) but you can still see people moving and stuff, i want it like smoke, like the dark swarm but gray
So you want there to be fog of war present, but you want to see under it? I don't think that's possible. Sorry.
no mean like a gray dark swarm somthing to make a smoke from explosions like after a uek hits have smoke there or when you go into battle theres smoke...
There are no effects like that. =(
Just go the regular route and use the traditional blueish fog. Gray fog isn't possible unless you inted on making a modded SCMLoader map; as Kenoli said.
Blueish fog = pylon overlay sprites + moving observers.
Use some dark terrain, close to the color you want and make observers. Basically the blue, but you are using terrain for the effect instead.
map revealer + obs rapidly moving on top (obs fuz up vision)
If you cant do it, imporivse
