This add-on allows users to render and composite a cavity pass to simulate bevels and light effects on geometry edges. Accessed through the N-panel, it provides basic controls for adjusting the spread distance and includes a low-contrast preview mode to check settings before rendering.

Once configured, the add-on computes the processed cavity pass and automatically inserts the resulting image into the compositor node tree. Users can optionally create a dedicated cavity pass group node during this process, allowing for precise control over edge brightness and colors directly within the compositor.
