# Navigation System

- Agents navigate using pathfinding. "generates a Navigation Mesh from the collision geometry in the Level and divides the mesh into tiles. These tiles are then divided into polygons to form a graph"; each polygon has a cost; agents choose lowest overall cost path.
- Modifiers change polygon costs; Nav Links connect non-contiguous areas.
- Generation modes: Static, Dynamic, Dynamic Modifiers Only.
- Avoidance: Reciprocal Velocity Obstacles (RVO) and Detour Crowd Manager.
- World Partitioned Navigation Mesh; automatic Navigation Link generation.
