Overview

With the Multi Matte Render Element, 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 Multi Matte, 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 Matte a popular choice for compositors.

The Multi Matte Render Element includes anti-aliasing.

To represent all the objects or materials in a scene with just the available red, green, and blue colors, several Multi Matte Render Elements can be generated for a single rendering, each with different Object ID settings.

Properties

 

 

 

Consider for Anti-Aliasing – When enabled, anti-aliasing will be used where possible.

Red object ID – Sets the ID used for the red channel.

Green object ID – Sets the ID used for the green channel.

Blue object ID – Sets the ID used for the blue channel.

Use material ID – When disabled, Multi Matte considers the Red object ID, Green object ID, and Blue object ID values to be the Object ID and renders the R, G, and B channels accordingly. When enabled, these values are considered to be the Material ID.

Affect Matte Objects – Determines whether to include matte objects when generating the render element. A matte object is an object that has been assigned a Wrapper Material with the Matte surface option enabled.
