Masking

When rigging a character, there will be cases where you will want to be able to move some pieces to give the illusion of a rotation or move the pupil within the white of the eye without having the extra bit of the drawing sticking out of the character or eyeball. To do so, you can use masks to cut anything you do not want to be visible.

To mask an object:

1. In the Timeline view, make sure the keyframe is added on the object that will be masking the piece to cut.

2. From the Module Library view, select a Cutter module and drag it to the Network view.
3. Connect the object you want to cut in the Cutter module's right port and connect the Cutter to the Composite module.

4. Pull out a second cable from the masking object and connect it in the Cutter module's left port.

5. Your masking effect is most likely inverted and what you want to cut is probably showing. Click on the Mask module's yellow button to open the Layer Properties window. In the Layer Properties window, enable the Inverted option.

6. Using the Transform tool, you can now move the cut object within the masking zone.
