Hi there, my name is Christina Halstead and this is a tutorial for Toon Boom Harmony Essentials. And what I'm going to show you how to do right now is how to use the Cutter effect on your scene.

So basically, the Cutter effect is like a mask. If you've used masks in other programs, it basically... Whatever the Cutter tool is over, it will hide that part of the character. Or if you invert it, it will show that part of the character.

So I'm going to show you how to add that to your scene. DOG_MASTER layer, which is the group that has all the parts of my character right here.

And there are a couple ways that you can add that effect to a system. [Correction] to the scene. One way is to right-click and go up to Insert > and down to Effects and you can find the Cutter there. Or you can hit this little plus sign right here, just Add Layers, drop to Effects and find Cutter again that way. Or you can go to Insert > Effects and Cutter.

So I've gone and added Cutter to my DOG_MASTER layer. And you can see it down here.

Now nothing has happened to the character, because I don't have a matte. Which is basically the layer that the Cutter pulls from to know where to show or hide the layer that is being [cut].

So what I'm going to go ahead and do now is add a layer, a drawing layer, that has something you can use as a matte. Rename it as: matte. Close and Add.

And, let's see, we're going to use the Ellipse tool. I'm going to... Oh wait, it's already selected. I'm going to use the Auto Fill. So I'll make a white circle, instead of just making a white line. I'm going to drag that over here and let go. Okay.

So as you can see...whoops. That's why it's being affected. It's actually in my DOG_MASTER scene. et's take that out of there. There we go!

All right, so here we have our white circle. And all it's doing is it's actually showing up in the scene, because I haven't attached it to the Cutter. To do that, I use the plus symbol here on my Cutter layer. And that will drop down another little sublayer. And it will basically ask for you to put in the asset that will act as your matte.

In this case, I'm going to take the matte layer and drag it into that. And now, as you can see the white circle disappeared and so has part of our character. So wherever that white circle is is where our character cannot be seen. And I can actually move that around. And if we go to Cutter and look at its Layer Properties, we can see that there's actually no parameters or values that we can change at all.

The only think we can change is whether or not the Cutter is inverted. If we go ahead and do that, that basically means that anything within the circle, the matte layer circle, is what will be shown. And you can actually animate this effect, by animating the layer that is acting as the matte.

So let's say, we wanted to move or change the size of the matte. So let's go ahead and shrink that down. So we can just see the character's face here. I'm going to go ahead and extend our character here. And we're going to add a keyframe with [F6]. And it's already interpolated.

And we're also going to extend the matte, by hitting [F5] to extend the actual art drawing.

So now that we have that, I'm going to go to this point. And I'm going to say what the matte layer will look like, by the time the animation gets to that point in the timeline. There you go. So the circle is now huge. If I were to take the matte off, you'd see that the circle has changed shape, to incorporate the entire Camera view.

So if I go ahead and animate that, it's quick, but you can see that it does change shape, because the drawing layer, which acts as a matte for our cutter, animates, therefore the Cutter animates.

And that is how you use the Cutter effect.
