How do I get the grid graph to recognize obtacles?

Is there a trick to getting the grid graph to recognize obstacles? I put a big rock on my scene and the walkable graph goes right thru it. I even put it on a layer call Obstacles and set the graph Obstacle layer mask for the graph to Obstacles and the graph still goes right thru it. The odd part is it recognizes the node my soldier stands on as an obstacle.

Hi

Are you sure the object in question has a non-trigger collider too?

Ok, the trick is the collider. Does the Obstacle layer mask really do anything?

Sure it does. If the collider is not in a layer included in the obstacle layer mask, then it will not be detected as an obstacle.
