Depth Matte (Pro only)

The Depth Matte effect reads the z-depth information in a 3D channel image file and can slice the image anywhere along that z axis. Use this effect to create a matte for everything in front of or behind the value you specify. For example, remove a background in a 3D scene, or insert objects into a 3D scene. Simply create two layers with the 3D channel image file; then, in one layer, position everything behind a certain point. In the other layer, position everything in front of that same point, so that the two layers together make up the original image; then insert a layer between them with the object that you want to composite into the scene.
