Depth-Based Compositing in NUKE

Learn how to combine depth maps to create correct layering between two renders

This allows us to split out scenes into multiple render layers while keeping the correct pixels on top

We'll begin by taking a look at what is depth-based compositing, or layering, and why we would want to use it

Then we'll learn about some of the downsides of using this technique

We'll then dive into NUKE and create a matte for our foreground layer using its depth map and the background depth map

We'll then learn how to work with depth maps, including combining maps from different scene scales, using depth-based layering to fix interpenetration issues, and making depth maps human readable and error-free
