There is an additional tab named 'Target Parameters' where you can adjust the way Entities navigate to the Focal Point when they can't 'see' it due to obstructions. The tab contains a checkbox labelled 'Use Focal Point Navigation'.

If you check this option, Entities will auto-navigate to the Focal Point and, once they can see it, will cross the Focal Segment at the nearest point. If you leave the option unchecked, Entities will head towards the nearest visible point on the Focal Segment whether they can see the Focal Point or not (this method can create more realistic movements but may also slow the software's performance).
