And this is how XPresso works, it works by connecting nodes together, so in After Effects you would write lines of code or text separated by full stops. All we're going to do, is first of all, create a couple of nodes. Now, it brings up the XPresso Editor, which may seem a little bit scary, but don't worry too much about it. And the first thing that we need to do is go into our tags, Cinema 4D tags and add an XPresso tag, and that allows us to start using XPresso to write scripts.
So the weight value is part of the random factor object so that's what we're going to add the expression to. So what we're going to do is take that weight value and add an expression to it.
I don't want to have to key frame it individually. So what I want to do is I want to get something controlling this so that it's animating over time. So were getting some addition animation by stripping that weight value. But if I go into Fall Off and adjust the weight, it also adjusts the color. So you'll see that when I adjust the strength, okay, it adjusts the strength of the, the position, scale and rotation nicely. And in here, what I've done is in the parameters I've had it apply the animation to both the color, position, scale and also rotation, I think. And in here we have a random factor object which is applying this kind of random animation. We're in chapter 7:01, if you want to follow along. It's quite a different interface and a different way of applying it, but the same logic really applies. I'm going to show you how you can create a similar expression in Cinema 4D. Anyone who's used After Effects will have undoubtedly used the wiggle expression in After Effects, which is useful in so many ways.
