Manual off mesh link for navigation wrapping

I am trying to create a wrap-around navigation mesh (so a square in which one side connects to the other). I have manually created off mesh links, but no matter what I do I can’t seem to get a navmesh agent to use the links to teleport to the other side. Instead it always takes the longer way of walking all the way back across the square.

I’ve confirmed the following things:

  • Auto Traverse Off Mesh Links is set to true on Nav Mesh Agent
  • NavMesh Agent Area Mask set to Everything
  • Off Mesh Links are Bi Directional
  • Off Mesh Links are Activated
  • Off Mesh Links Navigation Area set to Walkable (Also tried Jump)
  • Off Mesh Links are Navigation Static

Am I missing something else important?
Thanks for any help!

Seems that forcing use of a link by creating an un-passable obstacle (block bisecting the walkable area) allowed use of the off mesh links. Also changed the links to not static and the cost override to 0.
