Hi i saw a youtube video where an admin can become anything in the map, lets say the admin becomes a hemp fiber and starts knocking on doors, trolling players... would like to have that and become something on the server and start using lets say hemp fiber as a prop and walk arount like a little tree... this would me nice. anyone know if it was ported to umod from oxide?

There are no public plugins for that to that extent. It would be for Oxide regardless, as uMod builds do not exist yet. Oxide and uMod are not the same thing.
