Matte-Composite Node

T-COMP2-005-003

The Matte-Composite node is a type of composite that is specifically designed to combine different matte drawings into a single matte, which can then be connected to the matte port of an effect or drawing node.

Contrary to a regular composite, the Matte-Composite node allows deciding whether each drawing connected to it is added, subtracted or intersected with the resulting composited matte, and each drawing connected to it can be composited as is, or inverted.

Connection

Like a regular composite, the Matte-Composite node can be connected to as many input images as needed, and combines them together. Its output port should be connected to the matte port of an effect.

The matte is generated by creating a matte from the first drawing connected to it, then compositing each subsequent drawing on top of it. Like with a Composite node, the order in which connected drawings are composited goes from right to left.

Each node connected to the Matte-Composite's input ports has its own composite mode as well as its own invert setting. In the Node view, you can immediately tell the mode in which the node is applied by looking at the symbol just below each input port:

• A sign means the drawing is added to the composite matte.
• A sign means the drawing is subtracted from the composite matte.
• A sign means the drawing is intersected with the composite matte.

You can also tell whether the node is composited as is if the sign is black on white , or inverted if the sign is white on black .

TIP: In the Node view, you can quickly toggle between composite modes by double-clicking on the symbol. This will cycle between Add , Add Inverted , Subtract and Intersect . If you want to set a connection to another combination of composite mode and invert setting, you must do it in the layer properties of the Matte-Composite node.
