Initial points shouldn't be automatically created

[Roland09]

The GameObject should only act as a container for Path Creator. It shouldn't have points created automatically at the position where the Path Creator GameObject is placed. The first points (origin points) should be created when the user clicks on the terrain.

Current situation: You create a GameObject, add Path Creator, shift+click on e. g. a terrain and have the path automatically created from the GameObject's transform position, which could be anywhere.
