Quick Question Regarding Creating (TF2) Weapon Replacements.

[DY357LX]

Lets say you want to create a model to replace the Scouts' baseball bat (both a view model and world model), would you need to model the weapon and the hand that holds it, or just the weapon itself? (i.e will TF2 default to a default hand model or will appear as if the weapon is floating without a user-made hand model?)

Thank you.
