Cryptomatte AOV


The Cryptomatte AOVs work with the Direct Light and Path Tracing kernels to render Cryptomattes for use in compositing. They are rendered one at a time, and they contain the masks for all object layers or materials in a scene (figure 1). The masks also have correct anti-aliasing, and they take into account other features such as motion blur, transparency, and depth-of-field.

An IPR image contains shading and lighting data including some for visibility, in addition to the software render. Window displaying the Object Node Cryptomatte AOV type
