I thought making meshes to block and “Can Affect Navigation” was enough, but Building paths keeps adding green navigation to them, is there a checkbox for meshes not to be walkable so the Building paths process ignores them?
The first solution that comes to mind is using a Nav Modifier Volume. It’s a box that can be sized to your liking and you can set the Area Class to NavArea_Null to exclude nav mesh from it. Check out the NavArea types, hover over each of them and read the tooltip, there’s some interesting choices.
There are alternatives as well, but from what you mentioned, I’m assuming you need to do it in several places. Would this be suitable or would you like to control it specifically with the mesh itself?
