What do you mean with "FADE IN and FADE OUT do not work as expected"??
Here is what it does, quoted from skullar:
FADE IN and FADE OUT
Although you will find the fade SEXPs easy to understand, there is a minor thing you have to pay attention to :
You can only fade in after you faded out. So, if you, for example, want to fade in from black at beginning of mission, you have to fade out before. This fade out has to be instantenious, for example :
( - ) Fade in at mission start
- when
- has time elapsed
0
- fade out
0
- fade in
3000
This creates a nice fade-in effect from black.
"There is no FADE IN and FADE OUT in the current version of FRED2 included in the DVD"
Fade in and out is in all fred builds.
