First Vertex

First Vertex

When pasting in shapes or radically changing the existing
mask by adding and deleting points, you may run into
diffi culty lining up the points. Hidden away in the Layer >
Mask (or Mask context) menu, and available only with a single
vertex of the mask selected, is the Set First Vertex command.
If your mask points twist around to the wrong point during
an interpolation, setting the First Vertex to two points that
defi nitely correspond should help straighten things out.
This also can be imperative for effects that rely on mask
shapes, such as the Reshape tool (described in Chapter 7).
