What is the RemoteTransform3D Node?
It is a special node that pushes its own transform (position, rotation, and scale) to another node in the 3D scene. It allows a node to follow the transformations of a "remote" node instead of its parent node. This is useful for detaching a node from its parent's hierarchy to control its movement independently, such as making a camera follow a player character even if the player object is deleted, or making an object follow a path.
