Changing the buff graphic...

Okay, I've played with this for a while and I can't quite get it. I've succesful changed the 'aura icon' or the little icon at the bottom of the screen, and the text for it, but I can't seem to get the buff graphic to change. The spell I'm using is inner fire, and I want to change it to the manashield (blue ballish looking graphic around the player) instead of the little yellow crown above the head.

What I've done is this:
// Inner Fire
[Ainf]
Art=Abilities\Spells\Human\ManaShield\ManaShieldCaster.mdl
Unart=Abilities\Spells\Human\ManaShield\ManaShieldCaster.mdl
[...]
Targetart=Abilities\Spells\Human\ManaShield\ManaShieldCaster.mdl
Targetattachcount=1
Targetattach=Torso

Okay, well.. I've only really figured out that editing 'buffart' changes the little aura icon, but the other 3 are still kinda a mystery to me. So any clarification on what the above 3 art fields are for, and what I need to edit to get the manashield buff graphic rather than the crown (I currently get no buff graphic at all) would be appreciated.

I guess what I'm asking is if anyone can expalin, or direct me to a FAQ that explains what each of the art positions do, and how to edit them correctly so they work.

Edit: Nevermind that, i'm stupid :D

Since I haven't played around with SFX attach points, i'm not sure...but I don't think Torso's a position. Try one of these: overhead, head, chest, origin, hand, foot, weapon (for heroes), sprite(for buildings), medium (for buildings), large (for buildings). Then you can have a point modifier:
left, right, mount (for mounted units), rear (for quadrupeds), first (for buildings), second (for buildings), third (for buildings), fourth (for buildings), fifth (for buildings), sixth (for buildings), rallypoint (for buildings)

For example, chest left would do it to the left of his chest, or so i've come to believe.

Okay, thanks, but what exactly are the Art and Unart values for inner fire?

Oh yea, sorry. The Art is actually the ICON for the ability, the unart would be turning autocast off. The targetart is for the actual inner fire graphics.
