Effects the size of the border around obstacles. Many path planners (including CAINav) treat agents as a point on the navigation mesh. So the navigation mesh needs to be eroded by the agent's radius so the planner won't plan a path that comes too close to obstructions, or passes through areas that are too thin for the agent to fit.

Start with a value of ceil(maxAgentRadius / XZCellSize). A value of zero is not recommended.

Value: Waklable Radius
