The Depth Matte effect reads the depth information in a 3D image and slices the image anywhere along the z axis. For example, you can remove a background in a 3D scene, or you can insert objects into a 3D scene.

To insert a layer into a 3D scene, apply the Depth Matte effect to the layer containing the 3D scene, set the Depth property to the depth at which you want to insert the new layer, duplicate the 3D scene layer, select Invert for the 3D scene layer on top, and place the new layer between the two 3D scene layers in the layer stacking order in the Timeline panel.

This effect works with 8-bpc, 16-bpc, and 32-bpc color.
