Eyeon:Manual/Fusion 6/3D/Matte Objects

Matte Objects

Matte Objects are used for masking out parts of the scene using objects. Effectively, everything that falls behind a matte object doesn´t get rendered. However, matte objects can contribute information into the z-channel and the object-id channel, leaving all other channels at their default values. Matte objects are not boolean objects; they do not change or create any geometry. The effect of a matte object is global to the scene. To change the properties for downstream tools, use the Override tool.

Is Matte

When activated, objects whose pixels fall behind the matte object's pixels in Z do not get rendered.

Opaque Alpha

Sets the alpha value of the matte object to 1. This checkbox is only visible when the IsMatte option is enabled.

Infinite Z

Sets the value in the z channel to infinite. This checkbox is only visible when the IsMatte option is enabled.

Matte objects in the view cannot be selected in the display view unless the "Show Matte Objects" view option is ticked. However, it is always possible to select the matte object by selecting its tool in the flow.
