# Tutorial : Balloons with Newton2

## The final product:

Music: “Against My Will” by The Fisherman

You can download the AEP with Newton2’s settings (CS6 and above) here.

In this example, I wanted to illustrate the Gravity Scale feature in Newton2, and how we can use it to simulate flying balloons that interact with their environment.
Gravity Scale allows you to set a custom gravity per body.
I’ve used Connect Layers to represent the ropes attached to the balloons.

There’s no “Flying in the air” option in Newton, but you can somehow make objects fly if you use a negative Gravity Scale value!

You need to tweak some parameters to make it look correct: for instance, balloons have lower density and higher bounciness coefficient. I’ve also increased the Linear Damping value to fake air resistance.

To add a sense of depth in the animation, I’ve used the Collision Group feature: the pink and green balloons collide with each other, but ignore the orange balloon. The little squares that simulate the ropes can only collide with the walls.

I’ve animated the hand graphics using AE’s Motion Sketch. I wanted the ropes to start from a unique point, but animated freely when the hand releases them. I’ve simply parented the start point of 2 ropes to the animated one. Then in Newton, I’ve chosen the Kinematic body type for all start points. At the end of keyframes animation, when bodies become dynamic, ropes move independently!

Creating the ropes was made easy by the use of the Rope feature of Connect Layers. You just need to select the reference objects, and hit Rope.

One common mistake is to forget to place the anchor point of your objects to the desire place, where the rope must pass through. You usually think about this after creating the keyframes in Newton. To solve this, create a null object, place it appropriately, and parent it to the reference object. Then choose the null instead of the reference object for creating the rope.

# ASCII Generator

Music “Daft Punk – Get Lucky (Dualtrax Chiptune Cover)” by dualtrax

This After Effects script allows you to transform the content of the selected text layers into ASCII art. Credits must go to Patrick Gillepsie who wrote the hard part with his implementation of the FIGfont spec in JavaScript.

You may want to take a look at all fonts provided by the script: ASCII Fonts Grid

## usage

Select at least one text layer
Choose an ASCII font
Click on Generate

Compatibility: CS5, CS6, and CC (and perhaps with older versions but not tested).

## Quick Start Guide

You can grab a copy of ASCII GENERATOR on aescripts

# Create Gear

While browsing one of the Adobe Community forums to get info on Illustrator scripting, I came across this post and immediately thought it would be cool to port his script to After Effects. Gears are great shapes that can be used in various situations, but they are even better when you can animate them…

Note: There is an AE shape preset called Gear, but it uses 3 Polystars, 1 Ellipse and 3 Merge Path to create the gear (which makes adjustments more difficult).

# 3D Options Script

This After Effects script displays a palette that allows you to quickly modify the Geometry and Material options of the selected layers. If you want the panel to be dockable, place it into ScriptUI Panels folder.

[content_box title=”USAGE” color= blue toggle_status=”open”]
Select some 3D layers.
Execute the script and modify parameters.

# Cloth Simulation Test

Cloth simulation test done with AE scripting and expressions.

• particles (little circles) are setup on a grid
• particles are connected with springs
• force is applied
• finally layers are created at center of each cell, with expression-driven orientation and corner pin to fit the cell

# Text Bounds Expresssion

This After Effects expression allows you to determine the bounding box of a text layer. Continue reading

Reuben on Twitter was “Gutted to find out that Newton won’t allow me to make a Newton’s Cradle!”

Of course you can make a Newton’s Cradle Reuben with Newton, here’s a sample scene!

# Collage

This After Effects allows you to create photobook-style arrangements of selected layers. Continue reading

# Newton : A really great tutorial

Thanks to , here’s a great tutorial (Crash Dummy Character Rigging) using Newton.

There’s a lot of tips and tricks, so you better check it out!

# Linking layers to Trapcode Particular easily

In this tutorial, you will see how to create many lights at once that will work as emitters in Particular (and other plugins like Plexus…) using our CreateParticularLights script.

UPDATE:

22/05/2014: v1.2 Hide and shy source layers added.
20/05/2014: v1.1 Script has been to support shape layers.
02/10/2013: Script has been updated!
