The radius of the avoidance agent. This is the "body" of the avoidance agent and not the avoidance maneuver starting radius (which is controlled by [member neighbor_distance]).
Does not affect normal pathfinding. To change an actor's pathfinding radius bake [NavigationMesh] resources with a different [member NavigationMesh.agent_radius] property and use different navigation maps for each actor size.
