Overlapping Walkable on top of Obstacle won't work.. about navmeshplus HOT 4 CLOSED

Obstacle doesn't respect layers. See https://docs.unity3d.com/ScriptReference/AI.NavMeshObstacle.html
If you talking abstract "obstacle", so you need to change default navmesh to nonwalkable

oh right sorry, by saying obstacle I meant for "Non Walkable" override on Wall sprite, but what I am trying to achieve is to place a "Walkable" on top of "Non Walkable", so I was expecting a connection between the outer wall and inside navmesh. I also tried setting the default to Nonwalkable and overriding ground and overlapping image to Walkable, but navmesh isn't bridging.

Non-walkable overrides any region, you should mark only walkable space instead

Non-walkable overrides any region

oh, that makes sense, so basically, it is not possible without carving pixels out of the wall's image sprite, maybe I should consider that at run time, thanks for the help.
