2D layers in AE become rigid bodies in Newton.
Supports masks, text and shape layers.
Handles collision, friction, bounciness, gravity and more.
6 types of body (static, dynamic, kinematic, AEmatic, dormant and dead).
4 types of joints (distance, pivot, piston and spring) that allow you to connect bodies with specific constraints.
Provides clean, efficient and easy to use interface.
Fast preview, fast export to keyframes.
Comprehensive user's guide with illustrative animations for almost every property.
What's new in version 2.1
・Settings are not tight to a composition anymore! We added a Load Settings dialog that allows you to choose between layerID (AE internal identifier, comp specific), layer index or layer name, when importing settings file. In previous versions only layerID was used.
・Randomizer: Allows you to randomize the value of mostly any settings in Newton.
・Copy/Paste body settings
・Copy/Paste joint settings
・Loads of bug fixes
