Severals floors navmesh doesn't works.

Hello,
I’m currently works on a VR experience to visit a plant, imported in datasmith without collision.
I have put some cubes to make the floors naviqvation, that works very well.
When i i put the navmesh boundary on each floor, it works perfectly, but when i want to include all my floors, only the upper floor get the navigation.
Is there a way to resolve it ?
I’ve tryed to set up the agent height, but still the same error.

Thank you very much for your responses.

It’s about the agent height :blush: Try lowering it from the recast nav mesh.
