About Newton 4

Newton 4 is a native After Effects plugin from Motion Boutique that brings 2D physics into a composition. It transforms 2D layers into physical objects with realistic motion, letting you build interactive physics setups directly inside After Effects.

The plugin includes several body types, such as Triggermatic, Hidden, Waterlike, and Grenade, plus a Teleportation mechanism and a Weld joint for connecting objects. It supports null layers, provides a Loop Type option in the Keyframes panel, a Samples Browser dialog, and middle‑mouse‑button panning in the preview. Recent releases refined Comp Walls settings, the Randomizer, body selection in the preview, and the UI with SVG icons.

Newton 4 runs with After Effects 2020 through 2026. Version 4.0.77 fixed a high‑DPI monitor bug on Windows. The catalog lists it as free, while the developer describes it as a one‑time purchase with an optional trial that exports up to 25 frames.
