Refining the build with the Step Effector
Video: Refining the build with the Step EffectorNo, I personally get kind of stoked whenever I get to work with effectors. Because I really feel like they take working with Cloner objects up to the next level. Now, if we scrub through our animation here. You can see we have sort of an interesting thing happening. We have these Cloner objects fading out throughout the scene and then our little camera move that sort of flies through the worm hole if you will. And then a soft sort of flower panel resolve. Well, at the start when this fans out, I'd like these objects to all scale as well as rotate a little bit.

In this installment of Mograph Techniques, Ian Robinson shows you how to model and animate a stylized 3D flower that grows and blooms over time, using the combined power of CINEMA 4D and Adobe After Effects. You'll start by creating a single flower petal with traditional polygonal modeling techniques. Then you'll load the petal into a cloner object, and nest that cloner inside another, resulting in a complete flower with multiple levels of control for animation. The second phase is animating the cloners and refining the animation with the Step Effector. In the third and final phase, you'll bring the project into After Effects to add animated color effects, transitions, text, and shadows.

Refining the build with the Step Effector
No, I personally get kind of stoked whenever I get to work with effectors. Because I really feel like they take working with Cloner objects up to the next level. Now, if we scrub through our animation here. You can see we have sort of an interesting thing happening. We have these Cloner objects fading out throughout the scene and then our little camera move that sort of flies through the worm hole if you will. And then a soft sort of flower panel resolve. Well, at the start when this fans out, I'd like these objects to all scale as well as rotate a little bit.
And I'll do that using a step effector. And I'd like that effect to step through all of these different Cloner objects as it's being applied. So let's select our petals cloner object and then go up under Mograph, under Effector and apply the Step Effector. Now, I've already gone through all the different options, so I know exactly what I would like to set up. So, let's go to the Parameters section. And, under Parameters, enable Position as well as Rotation. Let's change our Y values for the postion to a value of minus 118.
Now, for the scale, I want things to scale up from a small value. So let's go and change our scale to a setting of minus one. Now it's going to go ahead and find out and scale tiny. Now to add a little bit of rotation, let's change our h rotation value to a value of negative 24. Now it looks like these objects are fanning out as they begin to create our tunnel shape. If we scrub through the animation, you can see it sort of looks like Franken-animation.
And that's because we want to control exactly when the step effector is being applied. Now, I kind of like how this starts, and I don't want the effector to start disappearing until about frame 12. So, let's move to frame 12 and go to the Effector section, and add a keyframe for our strength. This is where I want the strength to start fading away. So, let's scrub down our timeline here and move to about frame 65. Right here I want the effector to be at a value of zero. So let's change our strength setting down to zero, and add a second key for it.
Now if I scrub through, it looks kind of cool, but the start doesn't look quite right. Well, we can choose how we want these parameters applied. If we go to the parameter sections and adjust the transform space. Let's change the transform space from the no transform system to the actual object transform system. Now this is looking much more collected in its animation. Now when it fans out, I've got something that looks a little more organic in how it's been created. Now we'll continue to smooth this out inside of After Effects when we turn these little things into kind of a blobby effect.
But we'll get there soon enough. If you want, you can go ahead and preview this animation. Now, there's one last thing I'd like to show you with effectors. If we go to the Effector channel, under the Spline section, we have a nice eased curve that's showing how the strength is being changed throughout its application, but I can kind of adjust how this is flowing through the object. So for example, if I open up my spline options here and then just Ctrl+ click on my spline, I can move my spline here and click and drag to change the shape.
So now, instead of it just going from a small value to a large value, it's sort of going from small to medium back to small to large again. So, we can really kind of tweak how this works. Again just Ctrl+ click on the line and you can really get some finite control. With how this is being applied. Now, of course, let's just undo that, so we can get back to that nice uniform, sort of swirl that we created a little bit realer. But, as you can see, you can get all kinds of extra control when you go to apply effectors to your different cloner objects.
