The Shapes node is a new addition in Conduit 2. Not surprisingly, it’s used to create and edit mask shapes.
A single Shapes node can contain any number of shapes, and a shape can contain any number of control points.
The Shapes node provides editing controls which can be viewed on top of any other node's output.
This tutorial offers a quick overview of how to create shapes; edit shape points; work with smooth curves; view shape editing controls in another context; and export shapes to a text file.
