Depth-Based Compositing in Composite
In this series of lessons we'll learn how to combine depth maps to create correct layering between two renders. Software required: Composite 2011 and up.
What you'll learn
In this series of lessons we'll 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 in to Composite 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. Software required: Composite 2011 and up.
