Force an object to ignore walkable height

Hi, is there a way to force a staircase with mesh to ignore walkable height when the graph is built. I’m trying to avoid the isolated graph parts under objects using height, when I scan the recast graph. Unfortunately this means my second story stairs no longer have any of the recast graph on them. I was wondering if there is a way to force the recast graph to build on them.


This is not possible since the walkable height step is done much later when the system doesn’t even know what the original meshes were. However, if you use the beta version (and use Unity 2020.1 or later) then you can use a collider and position it under the stair. In the beta when using Unity 2020.1 convex colliders are solid, which means that no navmesh will be generated inside them.
