Join Angie Taylor for an in-depth discussion in this video Create RubberPin legs, part of RubberHose Animation with After Effects.
- [Narrator] Another way to create animated legs is to use the final mode which is this one, RubberPin mode. It's a slightly different work flow here but it's fairly similar. Now, the first thing we need to do in RubberPin mode, is create a single layer. We can't work on two separate layers. So I'm going to select the right leg and the right boot and I'm going to pre-compose it. I'm going to call it Right Leg. And we'll move all attributes into the new composition and click OK. Now you'll see that that composition is the same size as this Comp. If I want to trim it up, I can go into my Right Leg and then if we double click this tab to open it, we can use the Region of Interest button just to draw an area around the area we want to keep.
And then say, "Crop Comp to Region of Interest". And if I jump back to my Gardener now, I'm back here. Now, I can just drag that down into position and then we can start animating. Now, I'm going to switch off these layers so we're just focusing on this one. And I've already typed Right Leg into the name and I've got Hip Ankles selected and then I need to click on RubberPin but before I do I need to add some Puppet Pins. So, I'm going to add one up here and one roughly where the knee would be and then one at the foot. And then we're going to hit "U" on the keyboard.
And that will just show us the key frames that we need to have selected. We need to select them in the order that they were created. So, I'm going to click on the word Position. Hold down Shift, and then click the other two in that order. And then it's as easy as this. I click on New RubberPin and it creates my RubberPinned leg for me. Now there's an extra layer that appears that we don't have in the other modes, called "Transform". And this allows you to move the leg around. You'll notice that the ankle and the hip are both parented to that. I don't generally use it, I prefer to parent my hip to the body.
So that's what I'm going to do here. I'm just going to parent my hip to the body. Let's just switch all of those layers on so we can see them. When I move the body, the leg will follow. Now you notice it's bending the wrong way so the other thing I'm going to do is go into my Ankle RubberHose 2 controls and type in minus one hundred so that when I move the body, the leg is going to bend in the correct direction. Now you'll notice there's a little bit too much deformation on there. So the other thing that I'm going to do is click on Center and just adjust that center bias, and that allows me to decide where the bend is going to happen in the leg.
So, if I just drag it up a little bit somewhere like that, maybe, and now as I move the ankle, for example, you'll see it bends up at the top there. Now, there are other ways of controlling this and we're going to have a look at them a little bit later. But that's how you can add a RubberPin mode to a leg.
