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.
