Smooth Curvature node
The Smooth Curvature node generates an curvature texture from its input.

Inputs
The Smooth Curvature node accepts a single grayscale image as input, interpreted as a heightmap.
Outputs
The Smooth Curvature node outputs the generated curvature map where dark values are crevices, light values are exposed shapes and grey values are neutral.
Parameters
The Smooth Curvature node has the following parameters:
the size of the generated curvature map
the intensity of the curvature calculation
