Navmesh works partially with mesh collision

Hi there,

I’m have some issues with navigation paths…navigation is mainly generated right, but some meshes’ collision are not taken into consideration. It seems that sometimes navigation takes borders of the mesh into consideration but also generates under or “inside” the mesh. It occurs with meshes with some bases but not hitting the ground totally, such as tables, beds, etc

As you can see, the bed and small table in the back have a box collision that takes the whole volume of the mesh, but navigation is still generated under them.
I’ve tried switching between complex/simple collision, and naturally with Navigation settings such as agent Height, Step Height etc but none of these change a thing…
Any ideas ?
