Curve Mask

Method

This node generates a mask by using a shape created using user created points.

With the scene paused and this node selected, you can create new points by left clicking in the viewport. Left click dragging moves the selected point around and right clicking a point will delete it.
Using ctrl left click dragging changes the curve of the line into and out of that point.
