I'm still honestly puzzled with this thread. For some reason I read all different things in each post.
I think what the original poster wanted to say was: a full body character, thus, seeing the arms, but also the feet for instance. Not the head or shoulders (it is first person view, no?)
Even if it is possible to put the whole thing there, even if we don't see the feet as VanB quite wisely says, where would we say that there's an animation of the feet moving when walking/running?
Hands is obvious: just put it on the weapon model. The rest, to me is completely impossible where we stand.
I'm pretty sure I know everything. Doubts are something rare in me and I am never wrong, as this signature can prove.
