Fadeing in and out nice and slowly

[warpo]

I'd like to use the effect in my current map that Blizzard used at the begining of the Undead campaign when Arthas slowly faded into the cinemat scene. And I'm not looking for the quick dissapearing like shadowmeld. I know how to get that green glow that was around him but they got the character to kind of slowly fade in, kind of like they did with Tichondrius when he was talking to Mannoroth in the Orc campaign of ROC. Any clues?

Wild guess: Etheral? Make a dummy unit and cast etheral on whoever is disappearin, makes em fade a bit.

I think this will work:

Trigger 1
     Events
          Whatever the event is that turns on the fading, preferably unit-related (With more information about what causes the fading, I could be more specific)
     Conditions
     Actions
          Add (Triggering unit) to FadingUnitGroup*
          Turn on Trigger 2
          Wait 2.00 seconds
          Turn off Trigger 2
          Remove (Triggering unit) fading FadingUnitGroup

Trigger 2
     Events
          Every 0.02 seconds
     Conditions
     Actions
          Pick every unit in FadingUnitGroup* and do (Actions)
               Loop - Actions
               Animation - "Change Unit Vertex Coloring" - set transparency equal to (Transparency of (Picked unit) - 1)

JASS might be better for Trigger 2, since it's supposed to run faster and this happens every fiftieth of a second, but I'm not well versed enough to do that yet.
