Stuck on obstacles

I am playing around with a project based of the tutorial. I added in my first obstacle. I added it to the exclusive obstacle layer, and set the collision mask to that layer.

Everything seemed to bake ok. But my agents are getting hung up on the obstacle. Is there a way I can increase the buffer size around an obstacle by 1 node width. If you see from the image below the area around the obstacle is just not large enough for the agents.


Sorry for the late answer.
You can use the Collision testing->Diameter setting. You can also use the erosion radius setting, but that is slightly slower, however it will also work on e.g bridges where there is no obstacle, just an absence of walkable nodes.
