With the Multi matte Render Channel, only three colors are possible: red, green, and blue. In comparison, other matte render channels can include many colors to represent each material or object in a scene with a different color. With Multi Мatte, a single R, G, or B channel can be used directly as a matte, eliminating the step of selecting the color in the compositing software. This ease of use makes Multi Мatte a popular choice for compositors.
The Multi Мatte Render Channel includes anti-aliasing.
To represent all the objects or materials in a scene with just the available red, green, and blue colors, several Multi Мatte Render Channels can be generated for a single rendering, each with different Material ID or Object ID settings.

Red/Green/BlueChannel Objects– Creates a list of objects/materials collections to be excluded or included in the respective channel. When set to Include, considers the list Red/Green/Blue Object List as an inclusive set. All objects/materials collections not mentioned in the list are not rendered with this render element.
