Doodad models wont show effect?

[Stryke]

If I cast Entangling Roots on my Barrens Tree, which is a building using the Barrens Tree model, it won't show the effect? How do I fix this? However if I change it into an Abomination it works..

I think it has to do with the program not knowing where to attach the effect. I don't think doodads have attachment points.

Is there any way to show the effect???

Erh... I guess you could create a special effect at the point of the unit via a trigger...

Ok, how would I destroy the Special Effect after 5 seconds?
Using waits will bug it i think since it's in a Pick Every Unit loop
my code:

Breath of Fire
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Katon Goukakyuu no Jutsu 
    Actions
        Set TempPoint = (Target point of ability being cast)
        Set TempUnitGroup = (Units within 200.00 of TempPoint matching ((((Matching unit) is A structure) Equal to True) and (((Owner of (Matching unit)) is in LeafNinja) Equal to True)))
        Unit Group - Pick every unit in TempUnitGroup and do (Actions)
            Loop - Actions
                Set TemporaryPoint = (Position of (Picked unit))
                Special Effect - Create a special effect at TemporaryPoint using Environment\LargeBuildingFire\LargeBuildingFire2.mdl
                Unit - Create 1 Dummy Unit for Player 12 (Brown) at TempPoint facing Default building facing degrees
                Unit - Order (Last created unit) to Night Elf Keeper Of The Grove - Entangling Roots (Picked unit)
                Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
                Custom script:   call RemoveLocation(udg_TemporaryPoint)
        Custom script:   call RemoveLocation(udg_TempPoint)
        Custom script:   call DestroyGroup(udg_TempUnitGroup)
