How to upgrade from Newton v1 to Newton v4?

For the release of Newton 4,  Motion Boutique has partnered with aescripts + aeplugins.

There is no upgrade discount for Newton1. If you require assistance please contact support and we will be happy to help.

For site licenses:

How to get an Education license/discount on Newton

To receive the educational discount on Newton 3 please open a support ticket and provide a valid student or faculty id.  The ID must have a photo and expiration date. If the ID does not have an expiration date, please also provide another document that has your name and expiration date along with your photo ID to prove you are an enrolled student or current faculty.  You will also need to create an account on our site (if you don't have one already) for us to apply the discount. Educational licenses are not valid for commercial work. 

Newton is not standard plugin, you’ll find it in the “composition” menu.

When I export the simulation, I sometimes notice a little gap between touching bodies.

Newton doesn’t have pixel perfect collision. A 1-pixel gap is often observed between two touching bodies. You can use the Collision Tolerance setting in the Global properties panel to reduce the gap but may introduce overlap or instability when collision occurs.

Sometimes I notice tunneling effect with fast or complex moving bodies.

Try increasing the “Steps per frame” value. Increasing this parameter often yields better simulation at the expense of extra computation time.

I find it hard to select open shapes in the preview.

You can change the width of open shapes using the keyboard command Alt +/-.

When my scene contains multiple complex shapes, I observe a very slow simulation.

Make sure each shape has the minimum acceptable value for the “Mesh Precision” parameter. Reducing this value as much as possible always improves performance, and rarely reduces quality of the simulation. You can also use the “Convex Hull” setting (in the “Advanced” panel) to simplify your shape. Note that statistics about the scene (such as the number of polygons) are available in the “info” panel.

When I use mask Blending Mode or Inverted option, Newton doesn’t interpret correctly the shape.

Newton does not support Blending Mode nor Inverted mask. Newton only considers vertices defined by the Path property to construct body’s geometry.

OS compatibility

You need at least macOS 10.14 to run Newton 4.
