# Using Depth Compositing

## Using Depth Compositing

You can use a Z Depth or [World Position Pass](/element2/composing-element-3d/world-position-matte.md) to integrate other layers. What you could do is use a duplicate of your Element layer, set the duplicate to Z Depth from the Output/Show. You can then set that layer as a track matte for another layer to get it to appear behind an object.
