This node creates a mask from the convexity of a terrain.
For example, the image below shows the input terrain on the left and the convexity mask on the right.
We can then normalize the mask values to between 0.4 and 1, and apply the mask to the terrain.
To add a Mask from convexity node, right-click in the Graph editor and select Create Node > Mask Generation > Mask from convexity.
Double click on the node to open its parameters:
To edit a Mask from convexity node:
Convexity and curvature are two closely related terms. This node differs from the Mask from curvature node in the sense that it gives information on a much larger scale (the convexity or the curvature calculated on a very large number of vertices), while the Mask from curvature node provides the convexity or curvature at each of the vertices individually.

|Level||Softens a hard mask.|
