NavMeshAgent.radius has no impact

Its late so I'm probably missing something, but why when I adjust my obstacle avoidance radius does it have no impact on the nav mesh agent? Doesn't matter if its 1 or 8 (shown below) he still clips the wall hes going around. I appreciate any help.

 

follow up. yep, I was tired. feels like that radius just impacts other agents, not the nav mesh itself. to get a better path I set the radius for the agent type to a higher size and everything works great.

 

This is because the actual navigation mesh determines how close things will get to an edge. To support multiple sizes, multiple navigation meshes would need to be baked.

 

In more recent versions, the 'Radius' has moved to Obstacle Avoidance section, which helps with understanding its purpose.
