Which property determines how closely a NavMeshAgent can approach obstacles?

The Radius property of a NavMeshAgent is crucial as it defines the size of the agent. This size determines how closely the agent can approach obstacles while navigating along the NavMesh. Essentially, the radius is used to create a boundary around the agent, helping it avoid colliding with obstacles and ensuring it can navigate through tight spaces without getting stuck.

An appropriate radius allows the NavMeshAgent to maneuver around objects effectively, maintaining a safe distance from them based on its radius while still being able to navigate around them without difficulty. If the radius is too large, the agent may overly avoid obstacles and, conversely, if it is too small, the agent could collide with them. Thus, the Radius property is the key determinant of the agent's interaction with obstacles during navigation.
