Matte Object
When this attribute is on, the attached objects act as a matte holdout. Matte objects are not shaded and behave as if they were completely opaque, hiding any objects behind them, but appear in the image as transparent black pixels. This attribute is off by default.

| Value | Description |
|---|---|
| Invisible______ | The object is not visible to ray traced rays. |
| Opaque | The object is visible to ray traced rays; it is considered fully opaque and white. |
| Primitive Color | The object is visible to ray traced rays; these rays will be affected by the object’s "Color" and "Opacity" attributes in a Geometry Attribute Node (see General). |
| Shader Color | The most expensive mode: the renderer will evaluate the surface using the attached shader to determine the color and opacity. This is the default option. |
