Animation - Lock Unit's head to face Unit (How to make it work?)

[Pharaoh_]

Hello, I have a model, whose head doesn't respond to the "Animation - Lock Unit's head to face Unit". What is it required for the model to have, in order to make it work? Can I easily make it?

are you sure it has bones in the head? otherwise, i'd say attachment point, try to look into that

Ok, first off, I checked the *.mdl file, and it has:
Bone "ValveBiped.Bip01_Head1". So, I guess it does have a head bone reference.
It had no head attachment, so I added one through Notepad. I added the attachment as follows:

}
Attachment "Head Ref" {
ObjectId 23,
Parent 1,
}

Well, the Parent 1 is the parent object I found on the head bone, mentioned above and the ObjectId is 23, because the previous attachment points were placed in ascending order, starting with 20, so I guess this would go 23.
Now, what's the issue:
The attachment point is not fully created; if I use a special effect on "head" attachment point, it creates it on the origin of the model, as if the bones don't follow an organised structure.
What else the problem could be?
I even tried in the Object Editor filling the fields:
(1) "Art - Required Animation names - Attachments" & (2) "Art - Required Attachments Link Points" & (3) "Art - Required Bone names", with the values (1) head, (3) head1 (the final part of the head bone I mentioned before) and still, I get nothing.

youre trying to say that the attachment point wont go in the head and goes to orgin instead?

Yes, even if it follows the parent object :/
Well, it still seems confusing. If I triggered Animation - Lock Unit's head to face Unit, it should make the origin face the unit
When I try to open the model in Magos' Model Editor, to add a proper attachment point from there, it won't let me, it brings an error...

This has nothing to do with attachments.
There are some internal bone names that are used by the Warcraft engine in-game, examples of these are bone_head and bone_turret. _{(bone_head is used in that body-part facing issue and bone_turret always face the unit being attacked, such as cannon tower)}

The problem there is named ValveBiped.Bip01_Head1. Change this bone's name to bone_head and you'll be fine.
