Why A* 3D not working?

I have created a hexagonal tilemap in 3D as shown below, but I’m not able to create a good grid with A*. It detects all the area as non walkable. Any ideas please?


I note that your grid’s base is slightly above y=0. Are you sure the graph doesn’t start above all your hexagons? Also. Make sure your hexagons are not in the obstacles layer.

Thanks! I unchecked the “height testing” option and it worked, although I don’t know if it’s the best way to do it…
