How to Create Dynamic 3D Product Animations in After Effects

FMCG brands don't just want a static photo of a snack bag anymore. They want dynamic, explosive product reveals that catch the eye instantly. This teaser shows a high-energy 3D packaging animation built entirely using native tools—arrays, null mechanics, and camera moves.

If you were to manually keyframe the position and rotation of 24 different chip bags across three flavors, the project would become a nightmare to edit. This tutorial shows you how to work smarter, not harder. By leveraging After Effects' 3D workspace, mathematical rotation arrays, and the power of Null Objects, you can create a swirling vortex of product packaging.

The Magic Expression

Even with the mechanical rotation handled by the Null Objects, we want the individual floating elements (like the onions and spices) to have their own organic life. That's where this simple expression comes in:

Applied to the Position property, it generates a unique, random float for every single ingredient, making the scene feel alive without a single manual keyframe.
