This allows for a seamless transition between manual keyframing and physical simulation, giving the user total control over the start and end of a movement. Workflow and Integration

Objects that follow their original After Effects keyframes but can still push other dynamic objects.

At its heart, Newton 3 creates a dedicated simulation environment outside the standard After Effects timeline. When you launch the plugin, it opens a separate interface where layers are treated as "bodies." You can assign different physical properties to these bodies, such as:

The software calculates the interactions based on mass, friction, bounciness (restitution), and velocity. Version 3.0.69 specifically maintains the stability and performance optimizations required for modern AE versions. Key Features of the 3.0 Series

Users can animate physical properties over time. For example, you can increase gravity or change an object's friction mid-simulation.

Newton 3.0.69 remains an industry standard because it solves the "unnatural" look of manual keyframing. By applying the laws of physics to 2D shapes, it provides a level of organic movement—such as a pile of boxes collapsing or a wrecking ball swinging—that would be nearly impossible to replicate by hand. It is an essential tool for motion designers looking to add weight, impact, and realism to their work.

Objects that remain fixed in space (like a floor or wall). Dynamic: Objects subject to gravity and collisions.

Newton 3 introduced several transformative features that moved it beyond a simple collision tool:
