Paint Mode
Connecting a mask to the effect mask input displays the Paint mode menu. The Paint mode is
used to determine how the incoming mask for the effect mask input and the mask created in the
node are combined.
Merge: Merge is the default for all masks. The new mask is merged with the input mask.
Add: The mask’s values add to the input mask’s values.
Subtract: In the intersecting areas, the new mask values subtract from the
input mask’s values.
Minimum: Comparing the input mask’s values and the new mask, this displays the
lowest (minimum) value.
Maximum: Comparing the input mask’s values and the new mask, this displays the
highest (maximum) value.
Average: This calculates the average (half the sum) of the new mask
and the input mask.
Multiply: This multiplies the values of the input mask by the new mask’s values.
Replace: The new mask completely replaces the input mask wherever they intersect.
Areas that are zero (completely black) in the new mask do not affect the input mask.
Invert: Areas of the input mask that are covered by the new mask are inverted: white
becomes black and vice versa. Gray areas in the new mask are partially inverted.
Copy: This mode completely discards the input mask and uses the
new mask for all values.
Ignore: This mode completely discards the new mask and uses the
input mask for all values.
Invert
Selecting this checkbox inverts the entire mask. Unlike the Invert Paint mode, this checkbox
affects all pixels, regardless of whether the new mask covers them.
Solid
When the Solid checkbox is enabled, the mask is filled to be transparent (white) unless inverted.
When disabled, the spline is drawn as just an outline whose thickness is determined by the
Border Width slider.
Point 1, Point 2, Point 3
These controls show the position coordinates of the three corners of the triangle. Each point
can be published, connected to other controls, animated with a path, or attached to trackers.
These tasks are performed by right-clicking the Position control or directly on the point in
the viewer.
Common Controls
Image and Settings Tabs
The Image and Settings tabs in the Inspector are also duplicated in other mask nodes. These
common controls are described in detail at the end of this chapter in “The Common
Controls” section.
