Setting Mask Options

You can control how a mask affects the matte. For example:

• Set the opacity, colour, and edge softness of the mask.
• Specify whether the effect is applied to the inside or outside of the mask.
• Adjust the offset of the mask from its axis.
• Turn a mask on or off.

2. Select the mask in the image window:
   • Click anywhere on the garbage mask spline.
   • Click the Geom node in the schematic.
3. Access the Garbage Mask menu.
4. Set the mask options. See About Garbage Mask Options.
