Cryptomatte is a method developed by Psyop for efficiently encoding accurate mattes. It typically uses three to five automatically generated render channels stored in a multichannel OpenEXR file which removes the hassle of creating dozens or hundreds of Multimattes. Compared to the Multimatte Render Elements, Cryptomatte offers the following: - Does not require a setup with object IDs, etc.
- Only requires a fixed number of additional render elements, typically four.

The Cryptomatte render element can be used for post-production using 3rd-party software plugins, such as the Cryptomatte plugin for Nuke or Fusion and Exr-IO for Adobe Photoshop. |
