The Multi Matte ID Render Element isolates objects with specific Multi Matte IDs for compositing purposes.


The Multi Matte ID Render Element provides a mask for individual objects and/or materials based on the Multi Matte IDs.

The Multi Matte ID Render Element contains no shading information at all; it only contains blocks of color that correspond to each Multi Matte ID. It uses the Multi Matte ID option available in the materials' properties.
