What is a YMT file?

YMT files mostly belong to OpenIV.

YMT files are specialized game data files used by Rockstar Games in GTA V to store model configurations and other in-game settings. They contain internal definitions for models and related data that the game relies on. Some YMT files use an XML structure to organize their data, which allows experienced users to view or modify settings when needed.

Usage details:

  • Primarily serve as model and game data files for GTA V.
  • Contain configuration details used by the game engine.
  • May be either in a proprietary binary format or partly text-based XML.
  • Are best managed using specialized tools such as YMT Editor OpenIV or OpenIV.
  • Require careful editing since improper changes can affect game performance.
