So I believe I someone mentioned it in the past but I'm unsure what it would be called. I just started to learn some simple blender stuff with models. My question is how best to attach things to the hands or head? I know I could just add a second model within unity and do some toggle stuff but if I recall a while back someone was talking about how they had extra parts within them shrunk down to almost no size that expanded(and moved?) when they did something.
