Navigation area under a building?

Unity Engine

I have this issue where my AI agent thinks he can go under this building.
I’m finding a random spot that the AI can walk towards. Then I use NavMesh.SamplePosition to find the closest spot on the nav mesh.

So idk whats the best way to handle this. Add a collider under the building so it gets rid of the nav mesh? Or figure out why he think she can go under the building.

i wouldn’t think i could set a path to that position since his Agent height is higher than that area Or also he would have to go through that wall that has no navmesh on it.

I tried setting autoTraverseOffMeshLink to false.
I do have autoRepath on. I do notice that he stops at the building. He doesn’t try to keep running into the wall. But i also have something on my controller that stops the controller from trying to run into a wall too by using a ray cast.

So I guess i don’t know if he is just making a new path cause that point inside the building becomes in valid or what. Guess i need to test a little more and rule some things out.

TargetPosition is the same as ActualNavmeshPosition.
so its not being repath.

Vector3 ActualNavmeshPosition = m_NavMeshAgent.destination = TargetPosition;

Apparently the entire building is all hollow out with no floor. Thats why the agent has enough height to fit inside it.
I don’t understand how the Agent can plot a path to get inside it. It would have to go past unwalkable areas.
