Skill Level Intermediate
- Welcome to Motion Graphics Weekly, where you up your mograph knowledge one week at a time. I'm EJ Hassenfratz, let's get our learn on. Dynamics is the real world physics engine inside of Cinema 4D. And it's extremely powerful, but the one shortcoming is the apparent lack of ability to combine the power of dynamics with the functionality of mograph effectors. In this week's video I'm going to show you how you can actually easily combine these two powerful features inside of Cinema 4D.
So here's a simplified version of that scene. I had a ghost body that's triggering the dynamics on this little dandelion. Basically what I want to do is scale down these little pieces as they float away. So they get smaller and smaller and smaller until they fade to zero scale, okay. So what I'm going to do is first bake out the dynamics. So I'm going to click on the dynamics tag and just click on bake all. And you'll now see we have this baking simulation pop up and it just completed and you'll see that we now have this baked.
And we can them scrub through this animation and see exactly what's going on. And there's our dynamics. So typically if you were going to scale some clones down you would go ahead and grab mograph effector. Grab a plane effector and let's just make sure this one's applied, yup. And let's rename this plane effector to scale down. Okay so plane scale down. Always good to rename your effectors so you know what they're doing. And what we're going to do is uncheck the position.
And we're actually going to have this scale down these objects, okay. So you're going to see that all they're doing is scaling down the objects that aren't effected by dynamics. So let me just bring this down to negative one and let's change this fall to a sphere. And we'll just position this sphere. We'll scale this up. And let's actually go into our fall off and click invert.
So what that's going to allow us to do is as these little pieces fall outside of this yellow boundaries, you'll scale down from 100% scale all the way down to zero percent scale by the time it reaches this red part of this spherical bounding box. So let's go ahead, and again you can see that this isn't actually doing anything to our dynamic triggered objects. So what we're going to do is a little work flow hack and that is to actually duplicate this dynamic object or dynamic cloner object.
So I'm going to hit command, click and drag. And this will be the duplicate. And I'm just going to delete the dynamic tag on that as well as all the effectors aside from this plane scale down. Then what I'm going to do is hide this older version, the version that actually has the dynamic supply to it. And then for these duplicated cloners to follow the same position as the dynamic version we're going to use what's called an inheritance effector.
Okay, and the inheritance effector is going to allow our clones to inherit the position, scale and rotation of all the clones on this dynamic trigger version. So let's go and place this inheritance effector first in the effector stack. And go check out our dynamic options. So in the effector we have an object that we need to define. So which object do you want to inherit? And that's going to be our dandelion seed head again with the dynamics applied to it.
And then we're going to check on this morph motion object. And this is very important because it's going to then recognize all the morphing motion from that cloner object. You can already see that this is actually the duplicate version. So these dandelion little stems, these little floaties are now following the position of the dynamic trigger points. But the nice thing is this is not effected by dynamics, so we should be able to have this scaled down.
So as you'll see, true enough, these little pieces, these little floaties, are scaling down offscreen and being effected by that plane effector scaled down. Now this is massive. And the inheritance effector is probably one of the lessor known effectors, but as you can see it's a game changer when it comes to being able to combine the dynamics world with the world of mograph effectors unlocking so many possibilities for complex animation.
Don't want to wait until next week to learn something new? Now problem. Here are other ways to feed your creative brain to keep you busy in the meantime.

Q: Why can't I earn a Certificate of Completion for this course?
A: We publish a new tutorial or tutorials for this course on a regular basis. We are unable to offer a Certificate of Completion because it is an ever-evolving course that is not designed to be completed. Check back often for new movies.
