# Using Depth Compositing

***

### USING DEPTH COMPOSITING

You can use a Z Depth or [World Position Pass](https://www.videocopilot.net/help/element/help_files_v2/compositing_element_3d/world_position_matte/) 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.

**Z Depth Start**:\
Control the start depth (white) and how it transitions to the End (black).\
\
**Z Depth End**:\
Control the position of the Depth (black)  \
\
**Clamp Output**:\
Limits the maximum depth value to 1 when using 32bpc.\
\
**Preserve Alpha**:\
Makes background transparent&#x20;

**Depth Compositing**\
• Use a Z-pass render to combine 2D stock footage\
• Use most 3D programs like 3D max, C4D & even Element 3D\
