Im still a tad fuzzy on the "tag" concept. Where would the bone thats a tag go? Theres a bone for the hand, so why not tag that bone? Then the object will move with the hand, and I and any other animator dont have to worry about an extra bone
OK, a tag is kind of like a bone, but instead of being attached to the same mesh or object as the rest of the skeleton it tells the game engine "When I want to attach a weapon to the palm of this models hand, this is where it is and how it will be positioned in the hand." With the palm of a hand, yes, you could probably get away without an extra bone to show where the weapon goes and how it fits in the hand, if you make the tag for the weapon a child of the hand bone which is the parent. Yes, you could just slap the tag right on the palm, but you wouldn't be able to do special animations such as having a character twirl a gun in his hand (showing off after shooting something).
An extra bone on top of the neck, for the head, is definitely necessary unless you don't want the character to be able to turn his/her head in any animation.
So if you include a "head bone" on top of the neck and animate it as if the model had a head, instead of putting a real head mesh up there you replace it with a tag that tells the game "this is where a head mesh will be, it just isn't included with this file."
It's kind of like having an armature controlling multiple mesh objects in the same scene, except one is replaced with a tag so that the other object included elsewhere with the game files goes there. The tag itself isn't really an object and isn't rendered.
I admit that's a clumsy explanation, parts of which you might already know, but I hope it helps.
Aside from FileFront, no. The SVN I used for my game stopped working.
If the file with the skeleton - just the skeleton - isn't too big in size you could attach it right to a post in any thread here, the max attachment size is currently 1024 KB, and you could also compress it in a .zip file to make it fit.
Alternatively you could email the whole thing, my email address linked to my forum profile takes attachments up to 20 MB or so if I remember correctly. I could then put it on my website server with the other files I've linked to, or pass it around other ways.
