.ynd

YND files (YND = Path Nodes) in GTA V define navigation paths for vehicles and pedestrians. They contain nodes and connections that control how traffic and NPCs move through the map.

Main functions

• Path nodes: navigation points that define waypoints
• Traffic routing: paths for vehicles
• Pedestrian paths: paths for NPCs
• AI navigation: used by AI to move around the map

Characteristics

• Binary format: not directly readable as text
• Location: typically in x64e.rpf\levels\gta5\paths.rpf or similar directories
• Editing: requires specific tools (OpenIV, CodeWalker, or dedicated YND editors)

Tools for editing

• CodeWalker: map editor with path node support
