Holdout

Holdout Shader.

The Holdout shader node is used to create a «hole» in the image with zero alpha transparency, which is useful for compositing (see Alpha Channel).

Note that the holdout shader can only create alpha when Properties ‣ Render ‣ Film ‣ Transparent is enabled. If it is disabled, the holdout shader will be black.
