> **Note:** Masks created from Mask By Curvature are most visible when selecting the Flat Color material.

## Mask By Curvature

Masks areas with the greatest curvature, targeting the highest peaks and deepest surface valleys.

> **Note:** Mask By Curvature operates in a single-use mode, meaning each tap creates a new mask based on the settings rather than layering masks with repeated usage.

## Strength

Defines the strength of the mask when the Mask By Curvature button is pressed.

## Blur

Defines the amount of blur applied to the masked polygons when the Mask By Curvature button is pressed.
