Adding a Matte Drawing to an Effect

Some effects can use, or even require the use of a matte layer. The matte layer is a drawing that determines the area that the effect affects.

For example, a Cutter effect needs to be connected to a matte layer, because it uses the drawing in the matte layer to determine which part of the drawing to cut out. However, a Colour-Scale effect can be used without a matte layer, in which case it will affect the colour of all of the drawing it is connected to, but if it is connected to a matte layer, it will only affect the colours of the part of the drawing that is covered by the matte drawing.

TIP Drawing layers can also be connected to a matte layer. When a drawing layer has a matte layer, the part of the drawing covered by the matte layer is cut out from that drawing, which is the same as if the drawing was connected to a Cutter effect—see About Masking and Cutting Parts of Elements in your Scenes.
