I have a question now, is the arm included in the watch model? As when I open the smd files in blender, they include the arm/watch. It's strange, because the watch model is actually inside the hand, and not attached to the wrist. Is this an import issue, or just how the bones are connected by TF2 afterwards?

How are they shown to other players then? If they're only v_models?

How can I find the name of the invis watch bone? I would like to play around with making a watch. Also, how do I 'decompile' existing weapons, such as an invis watch, to see how they work?
