Explore how to create complex physical animations inside After Effects using Newton (a third-party plugin) and the Connect Layers (a free script). This project-based course covers a few specific and popular types of effects, such as letters suspended from strings and connected, randomized spheres. Artist Eran Stern shows how to connect any type of element together in a complex 3D array of strings and work with different dynamic simulations in order to create Dormant and Collision as well as Staggering and Kinematic animation types.
These lessons are perfect for motion graphics artists who want to create earthy physics simulations and add realistic motion to their projects.
We are in the process of creating letters hanging and stretching on what seems to be rubber ropes. We already set up the initial state of this composition inside Newton, and saved our progress. So let's make sure that the composition is still selected, and let's fire up Newton and finish the animation. So since the Auto Load Saves settings is enabled in my system and we are entering the same composition without changing any one of the layers inside the after effect comes, we can preview the simulation so far and see what we have managed to achieve by connecting these dots as joints to the letters.
Okay, I want to finesse it a little bit and define couple of other steps inside the gravity and the solver here under the global properties. Let's start with raising the magnitude to a higher value. I'm going to go with 13, and this will make the gravity to pull the letters a little bit more towards the bottom of the screen. Which will also create some kind of a weird behavior when the letters are actually colliding with themselves.
You can control this behavior under the solver here with the Collision Tolerance. So by reducing it to a lower value, say, 15, you're actually asking the solver for a less chance that the letters, each one of those letters, will collide with one another. So let's go to the beginning, and create another simulation test. And I think that this springy behavior is much more interesting than the one that we had earlier.
Now, you can still select individual letters and change their behavior over here, but for our purposes, what we got so far is quite nice. Note that you have other options for the joint as well. Which we are not going to cover in this example. But, do play with them because they are very fun and can yield an interesting result. For now, I think that we are done using Newton to solve this, and the only thing which is missing here is the rope simulation itself.
We will create the rope simulation in the next movie, but first we need to export our solution. So, I'm going to enable Motion Blur, make sure that I'm applying my solve to a new composition, and, hit Render. Since this is a simulation, your result and my result may vary. It will look a little bit different each time you will create it. But, we will, more or less, get the same results. Now we have the second composition named rope letters number two.
Let's open it up inside After Effects. For now, I'm not going to enable Motion Blur, I'm just going to ramp preview this composition to get a sense of what we've been able to achieve so far. >> We're faking experiences, so we'll have something to share. So we can feel alive. >> Okay, this looks great, and now we are ready to create the ropes themselves, which we're going to do in the next movie.
