Complete GTA 5 Modding Reference 2026 — All Files Explained

Complete GTA 5 Modding Reference 2026

GTA 5 uses dozens of proprietary file formats, each serving a specific purpose in the game engine. This comprehensive reference for 2026 catalogs every important file type, explains its function, and points you to the right tools for editing — your one-stop guide to understanding the entire modding ecosystem.

3D Model and Visual Files

YDR (Drawable) files contain static 3D models with materials and shader assignments — used for buildings, props, and non-destructible objects. YFT (Fragment) files hold destructible models with physics breakpoints — used for vehicles, fences, and anything that shatters. YDD (Drawable Dictionary) files bundle multiple YDR models into a single package for efficient loading. YTD (Texture Dictionary) files store collections of textures referenced by models, organized by name matching conventions.

World and Map Files

YMAP files define object placement in the game world — position, rotation, LOD distances, and flags for every static prop and building. YTYP files contain archetype definitions describing object properties like physics type, texture dictionary, and bounding box before they're placed in YMAPs. YBN (Bound) files provide collision geometry for physical interactions. YENV files control environment settings including weather transitions and lighting configurations for specific areas.

Configuration and Data Files

META files (XML format) configure game behavior: vehicles.meta defines vehicle properties, weapons.meta controls weapon stats, peds.meta registers character models, and handling.meta sets driving physics. DAT files contain specialized data: gameconfig.dat sets engine limits, popcycle.dat controls NPC spawning patterns, and visualsettings.dat configures rendering parameters. These text-based files are the most commonly edited in modding since they require no specialized tools beyond a text editor.

Audio and Animation Files

AWC (Audio Wave Container) files store sound effects and music tracks in compressed format. REL files define audio relationships — linking sounds to events, objects, and environments. YCD (Clip Dictionary) files contain animation clips organized into dictionaries for character and object animations. Understanding these formats enables complete customization of how GTA 5 looks, sounds, and behaves — making the difference between a simple texture swap and a total conversion mod.
