Fog Effects?

I need to create fog that is seen like normal fog in real life from a 1st person view
I want the fog to fill the sky, not be just on the ground.

please help me.

Pretty sure there's no mechanic for doing what you want to do. Maybe with tricksy cameras you can fake it.

you can set the fog in map properties,but that will be permanent.

Maybe with a custom fade filter you could do it, however the fog wouldn't move around. Try with a white fade filter at 35-40% maybe?

In the object editor, the might be a way to edit the fog itself. If there is, try chsnging the flying height, orsomething along those lines.
