With the MultiMatte Render Channel, only three colors are possible: red, green, and blue. In comparison, other matte render elements can include a multitude of colors to represent each material or object in a scene with a different color. With MultiMatte, 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 MultiMatte a popular choice for compositors. The MultiMatte 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 MultiMatte Render Elements can be generated for a single rendering, each with different Material ID or Object ID settings. |
