Now when you move the effector over the cloners, they scale into place. Simply click on Invert in the Falloff tab. Although we want them to appear, not disappear as it moves on. We want the effector to start on the left side of the cloners and move to the center of them. Move the effector to the left a bit and you’ll notice the clones will slowly fade into view. This is easier to do in the Front viewport. You’ll want to center the plain effector onto the cloners. Instead of animating a straight line, it’s more interesting to get more of a “V” shape as they animate on. Change the Shape from Infinite to Capsule. Right now, our clones are affected no matter where they are in our scene. To get a better visual of what we’re doing, we need to change the Falloff shape. We need to scale our clones to essential 0%.
We don’t want to animate Position, we want to animate Scale. By default, the position is set to 100cm in the Y Axis. Click on the effector’s Parameter tab in the attribute manager. Select both Cloners in the object manager, then go to MoGraph → Effector → Plain. For the purpose of this specific wipe, we’ll want to use a Plain Effector. Effectors take existing clones and vary their position, scale, and rotation dependent on the Effector’s location. To animate the scale of each piece, we’ll want to use an Effector. Along with the scale, we’ll want to animate the color of each piece from white to black. Create a Plain Effectorįor the animation, we want each diamond piece to scale from 0% to 100% from left to right. It doesn’t matter if moved left/right or up/down… as long as it’s moved into the gap. Then move it on the Y axis 300cm (half the height of the diamond shape). We want to move it 180cm (half the width of the diamond shape). To move the new Cloner into the exact position, start moving it on the X axis. We need to duplicate the Cloner object and move the other pieces into the gaps. 😛 So that will give us half our grid pieces. For the size of each one, I got to these values by multiplying the width of our diamond (360cm) by the count (minus 1). This is 13 diamonds wide, 5 diamonds high, 1 diamond deep. Just to Clarify, make sure the Cloner’s mode is set to Grid Array. The Cloner settings shown here are what will be used to create our grid. We’ll render the final animation at 1920×1080 pixels. We want the overall shape of the grid itself to be close to a 16×9 ratio, in order to fill an HD screen. This will make the Extrude object a child of the Cloner object.
With the Extrude object selected, go up to MoGraph and while holding Alt (Option on Mac), click on Cloner. We’ll do this by putting our diamond shape into a Cloner object. We don’t need any extrusion depth, so in the object manager, make sure all the Movement values are 0. This will make our spline object a child of the extrude object. With the 4-Side spline still selected, go to Create → Generators, and while holding Alt (Option on Mac) on your keyboard, click on Extrude. Next, we need to extrude the spline so that it has a flat face. This will give us a somewhat symmetrical diamond shape. Enter 360cm for the “a” value, and 600cm for the “b” value. In the Attribute manager, make sure the Type is set to Diamond. Let’s start by creating a 4-Side spline shape. The first thing we need to do is create the diamond shape that makes up the transition itself. So without further ado, let’s get started! Create the Diamond Shape The Studio version includes MoGraph, and you’ll need this to build the diamond grid. It’s somewhat of an advanced tutorial, so you’ll need some descent experience with Cinema 4D. I am going to use Cinema 4D & After Effects to accomplish this. This is useful for transitioning from one photo/video to another. With this tutorial, I’ll show you how to create a simple left to right wipe transition.
