When sketching characters with a background in Storyboard Pro, you might find that the outlines of characters clash too much with the outlines of backgrounds and that filling your character's outlines with white or another solid colour would make the panels more legible. However, since storyboarding is often a hasty process, you may not have time to fill each drawing you make manually.
The Generate Auto-Matte dialog box allows you to quickly create a colour matte to fill the inside of sketch outlines, hiding anything that is behind each object you sketch. The Generate Auto-Matte dialog will automatically determine where it must fill, even if the outlines have holes or are not closed outside of the camera frame. It will then fill the artwork by creating a layer underneath it and storing a solid colour matte in this layer.
- Select one or multiple layers on which the matte should be generated. The menu is grayed-out if there are no selected layers or none of the selected layers are non-empty vector layers. You may select multiple layers in one panel, or select multiple layers in multiple panels.
- Select Layer > Generate Auto-Matte.
- Select the required settings
—see Generate Auto-Matte Dialog Box.
- Click OK.
The new layer with generated matte is created and placed below the selected layer.
If a matte layer already exists, a dialog box will give you the following options:
- Replace the existing matte layer.
- Keep Both matte layers.
If this happens for multiple layers, selecting the Apply to All check box enables you to apply your decision to all layers without being prompted again during matte generation.
- Select Edit > Preferences (Windows) or Stage > Preferences (Mac OS X).
- Select the Shortcuts tab.
- In the Name list, select Layer > Generate Auto-Matte.
- Define the shortcut.
- Click OK.
