How would I make the players torso arms and head follow the cursor?

I’m trying to make it so when the player looks up, the torso, arms, and head look up as well.

I found this by CleverSource. but it is r15 only and my game is in r6.

Additionally, how would I make this server-sided?

For context, I’m trying to make it so tools follow the player’s view (like in fps games).

If you mean arms in front of the camera, you have to user a view model, if you mean the player’s actual character, then you can move the arms and head, but you cant do torso. you can update in a local script then user remote events to fire to the server to update it for everyone else.
