The Curvature node creates a mask where convex areas (such as sharp edges, protrusions, etc.) are selected. It is a very useful layer in texture creation, often as highlights applied on top of an existing texture map.
|Min||The minimum range of the curvature.|
|Max||The maximum range of the curvature.|
|Falloff||The soft falloff at the maximum edge.|
|Horizontal : Favor horizontal curvature.|
|Vertical : Favor vertical curvature.|
|Average : Blend both horizontal and vertical curvatures evenly.|
|Invert||Invert the map.|
