# Client files/custom models notes: ### Server > Doesn't work: - Server can't send existing files to the client to overwrite mdl and related files. - Server can't add "new" models outside of vpks, meaning you can't push the mdl files and expect them to work. > Does work: - Server can send models and related files to the client that aren't already used by the default game. ### Client > Doesn't work: - Clients can't overwrite existing mdl and related behaviour by placing them in corresponding folders. > Does work: - Clients can download mdl and related that aren't used by default in the game, and can function if the Server tells them to use them. # Test? - Can we properly merge bones of a standard model to a new model smoothly without breaking anims/hitboxes?
