Getting Navigation Mesh to go through doors? (Maybe not what you're thinking)

I can't set the nav mesh bake setting small enough to pick up the jump between outside and inside. I know if they were separate meshes I could do an Off Mesh Link thing, but I'm not sure what I can do if they're the same mesh (outside / inside). Is there any way I can force the nav mesh to connect?

 

Shameless bump? :3

 

I've come across the same issue. Do you have a separate collision mesh for your environment? If you do, what you can try is hiding all the art assets in your environment and try baking the nav mesh on your collision. Once you got your nav mesh, show all the environment assets.
