(Solved)Is there a manual way to connect navmesh or tell Unity where should bake?

There's a tent, but due to the mesh collider, the navmesh inside the tent is cut from out side, so there's no way in there. Could it be correct? Thanks!

 

Instead of using colliders on the tent, construct walls around it with either a series of colliders (such as boxes) or a series of static navmeshobstacles.

 

Thanks, I found that's because of the navmesh agent height in the baking option is higher than the tent door
