The Core Concept: What is a Null Object? At its simplest, a null object is a layer in your composition that has no visual presence. For example, you can use an expression to make a layer follow the position of a null object exactly, or even to move in the opposite direction, creating a parallax effect.

For instance, imagine a car animation; you could parent the wheels to a null object controlling the chassis, allowing the wheels to rotate independently via their own nulls, while still moving with the car. Practical Applications: Why Use Nulls? The true power of the after effects null object reveals itself in practical, real-world scenarios.
Instead of keyframing multiple layers individually, you attach them to a null object, and that single controller dictates their movement, rotation, or scale. Simplified Rigging: Create control panels for characters or objects, where one null adjusts the entire arm and another controls the leg.

For organizational clarity, it is a best practice to rename your null layer something descriptive, such as 'Control_Master' or 'Driver_Car', depending on its function in the scene. Establishing Your Null Layer Creating a null object is a straightforward process that takes mere seconds.
