Learn about additional layer options that will be useful for rotoscoping.
- [Instructor] We're ready to move on to rotoscoping in mocha. But, before we do that, I want to discuss some additional options in the Layer Controls panel. Right now, I have project 4-1 open and this has the doctor looking at the tablet. And I have a single shape here. Now, you can rename a layer any time you want to, by double-clicking the layer name, backspacing, and typing a new one. And then hitting Enter. mocha automatically names the layers, as you draw them, based on how many you've already drawn in the scene or the project and it'll just go 1-2-3-4-5 and so on.
Next option to the left is the color of the mat. So, if I show the mat, it's white by default, but I can change that coloring. There's also transparency option right here, under the toolbar. It's .5 by default, but I can make that larger, up to one, or lower, down to zero. Go ahead and hide that for now. Next option over is the color of the outline itself, color of the spline. This is red by default, but you can change that color. And this is useful when you have quite a few shapes in your scene or quite a few splines, which is often the case with rotoscoping.
Next option over is the lock. If you've tracked your shape and you've animated the shape and you're happy with it, you can lock it in such a way that you can't adjust it, until you unlock it. So, it's great for preventing accidental changes. Next button over is the process gear and, if this is on, mocha constantly updates the data. In other words, it tracks, it looks at the key frames, and so on. This is off, then no processing occurs. Next option over is the eye. You can turn off the visibility for a layer temporarily.
Of course, you can have as many layers as you want. And each layer has its own set of options, in terms of color and name and so on. Now, if you have a quite a few of these layers, it gets confusing. So, one thing you do is add a group. To create a group, right mouse button click over a layer and choose New Group. This is a folder. You can double-click on that to rename it. And, in order to add layers to the group, simply drag them into the group folder.
To pull them out, drag them back out. If you'd like to get rid of an old group, you can select it, right mouse button click over it, and choose Delete Selected. You can do the same with a layer. Select it and Delete Selected. You can also copy a layer. So, a copy's exactly like the original. Select the layer, right mouse button click, and Duplicate. The copy's identical, but then you're free to alter the copy or even alter the original. We'll delete that for now.
All right, so that's a few extra options you have with layers and these will be useful, once we start rotoscoping.
