I encounter the same issue on unity in the sample scene, and it works without any problems there. I’m not sure if that has anything to do with it.

Hey 
That’s unexpected. We’ve improved the sample further more. Please pull the latest commit on the navmesh branch. I hope the update fixes your problem 
The only thing you need to do is to have the Navmesh component in your scene. Also the mesh is no longer a part of the scene directly. So, you can delete whatever you have under the object with the Navmesh component.
Here’s a demo: https://engine.needle.tools/samples-uploads/navmesh/
Here is the relevant code for exporting the navmesh as a mesh to be used at runtime: needle-engine-samples/package/Runtime/Navmesh/Scripts/Needle.Navmesh.codegen/Navmesh.cs at a450b474133680339d1140d3830e3fd7000c6807 · needle-tools/needle-engine-samples · GitHub
Ok, ok, perfect. Really, thank you very much for the help. You guys rock!
