Hi,
I am trying to learn how to use NavigationMeshes to make an Isometric 2D world with pre-drawn maps. In such a map, it's possible for some navigable floor to appear "behind" a wall which supports another floor on top of it. This means that we need to have several meshes that are connected in one place but overlap in another, like this (see the top-left edge of the platform on the right):

I would like to be able to achieve that, but also to be able to programmatically bake those meshes for several different sized agents.

I was reading in the Connecting NavigationMeshes doc page that:

Alternatively NavigationMeshs are not merged but still considered asconnected by the NavigationServer when their edges are nearly parallel and within distance to each other. The connection distance is defined by the edge_connection_margin for each navigation map. In many cases NavigationMesh edges cannot properly connect when they partly overlap. Better avoid any navigation mesh overlap at all time for a consistent merge behavior.

This allows me to connect meshes even if they are offset when baked, but then I get some undesirable connections in the overlapping sections (as you casn se in the screenshot). Do you have any suggestions on how to solve this issue?
