Flying height

hey,i'm trying to make a spell (Hydra) that summons a hydra and a pit and a SFX. All of this works fine but i dont have any clue how to get rid of the tail without alphaing (wich i am not gonna do).

So i figured that if i lowered the Hydra it would only show its head(s), that should work. Now i have tried 2 different things to get the desired result.

1)Made a trigger:E:blablabla (the trigger works cuz the debug message says so)
C:blablablaaaa
A:Change (summoned unit) flying height to -100 (tried lots of values for that one) in 500.

That doesnt work.

2)Got into object editor and changed the movement height data fields, no response.I even tried changing the units movement type to flying.Doesnt work either.

/Thx in advance

I think it's impossible. When doodads die, their splinters fail under the ground but model itself doesn't because of use relative model coodrinates - I think negative height is impossible.

If you go to File -> Preferences, you should be able to click on a box that says "Allow negative values in object editor" - that should allow you to set the flying height to a negative number. You'll need to set the movement type to hover or fly to get the hydra hidden below the ground.

That said, you really should consider either alphaing out the tail or editing the model and removing the tail; it'd work MUCH better.
