I've recently been looking into animations within Unity, and came across the idea of splitting my humanoid character's object into two at the waistline. The Idea being that animations used for movement can be applied to the legs, without interfering with general upper body animations/stances (and vice versa). Is this a viable option and would there be any adverse effects from doing this?
Also, is there any real need? I've noticed Unity is quite flexible when it comes to animations, but am unsure whether unity would be able to handle this? My main issue is different weapon types, where I would like the hands in different idle positions, but without having to have 4 or 5 different running forward animations.
