Summary: This video will take you through the workflow of remapping a Z-depth render pass from absolute values to normalized values in order to make use of it in a compositing situation. Using a normalised Z-depth render pass is a requirement for all the various workflows of adding depth of field blurring using physical defocus and any other 3D post effects. We'll discuss the Z-depth information in detail as well as demonstrate the Depth Normalizer for the main purpose of remapping Z-depth data. This is very useful to know when handling Z-depth data from external CGI render passes.
