Weird Boxes shows up whenever Scanned

Whenever I hit “Scan”, there’re 3 suspisous boxes shown up as screenshot.

What are these boxes and what are they for?

If I hit scan repeatedly, those boxes will stay where they are. But if I change s.t like add another obstacle and hit scan, those boxes will move to different places.

Using Unity 2019.4LTS, Astar 4.3.28 (however this did appear in many older version too)

Best regards,


That looks very strange. Are you sure there are no colliders around that could cause these?
Do you recall if they appeared in the non-beta version too?

They are not Colliders since if I change anything in PathFinder and hit Scan, they will move to another places (but still within bound).


  1. I don’t know about non-beta version since my project followed beta quite some time ago.
  2. Those bounds seem not do anything significant (or anything at all) to my notice. At least I haven’t test if they intervene with paths.

I thought these might be something obvious. Apparently not. Will try to test 2. then.


Sorry for the late answer. I have been away for some time.
I have not been able to replicate this. Would it be possible for you to share a small example scene with me that allows me to replicate this issue?
