Editing Masks

Edit a mask the same way you edit any greyscale raster layer. Select a mask layer on the Layer palette, and then use the painting tools or the effects commands to modify the mask. When you edit a mask, you change either the areas or the degree of masking. For example, painting over an object to mask it changes the area, while applying a gradient fill edits the degree of masking.

Remember that a mask layer is a greyscale layer with 256 levels of grey that correspond to levels of masking. When you select a mask layer, the Materials palette displays the greyscale palette. Apply black or white to mask or erase the mask at 100 percent. Apply greys to vary the level of masking.

Edit the layer properties of a mask, such as the name, visibility, or opacity, in the same way you do any type of layer. For more information, see Editing Layer Properties.
