2 Draw the first garbage mask.
3 Switch to Result view.
4 Enable Region of Interest.
Outside is enabled and the Colour is set to 0.0 for the mask.
NOTE Disabling Region of Interest toggles the Colour setting back to what it was before.
5 Adjust offsets and softness as required.
6 To adjust the individual opacity for each mask, select the mask and then adjust the value in the Opacity
field.
7 Draw any other garbage masks as needed.
NOTE Each time you add a garbage mask with ROI enabled, Result view is temporarily cleared of all masks
so that you see the entire matte. This way you have a better view of what you want to reveal and mask.
Refining the Mask
You can adjust the softness gradient of a mask to smoothen its edges. You can smoothen the gradient towards
the inside edge, the outside edge, as well as the area where the inside and outside adjustments have an effect.
You can create a uniform gradient around the edge of the mask, or use an advanced gradient to control the
shape of the gradient at different parts of the mask.
To create a uniform gradient, you define how far you want the gradient to be offset from the edge of the
mask and then set its transparency. To vary the shape of the gradient, you move vertices on inner and outer
softness splines. The gradient will be based on how far each vertex point is offset from the mask.

Advanced gradient provides a versatile method for setting the softness of the mask edge. It applies a gradient
according to the distance of the softness borders from the garbage mask spline. It allows you to customize
the softness gradient at different parts of the mask. The advanced gradient has two softness borders, one
inside and one outside the mask border. It also includes inner and outer softness vertices for each regular
mask vertex.
