WFT File – What is .wft file and how to open it?
WFT File Extension
GTA 4 Car Model File – file format by Rockstar Games
WFT is a 3D file format used by Rockstar Games for storing car models in their Grand Theft Auto 4 video game. It stores mesh data, textures, and animation information for vehicle models.
Definition of a WFT File
A WFT file, also known as a GTA 4 Car Model File, is a 3D model file format used in the video game Grand Theft Auto IV. It contains the geometric data, texture coordinates, and other information necessary to render a vehicle model in the game. WFT files are typically bundled together with a corresponding .WTD file, which contains additional metadata and animation data for the vehicle.
Structure and Usage of WFT Files
WFT files are typically organized into a hierarchical structure, with individual parts of the vehicle such as the body, wheels, and doors being represented as separate objects within the file. The geometry for each object is stored in a polygonal mesh format, with vertices, edges, and faces defining the shape. Texture coordinates are assigned to each vertex, allowing the game engine to apply textures to the model. Additionally, WFT files may contain information about the vehicle’s suspension, steering, and other physical properties, which are used by the game engine to simulate the vehicle’s behavior.
Opening WFT Files on Windows and Mac
To open a WFT file on a Windows PC, you will need to download and install a third-party program such as Grand Theft Auto IV Modding Tools or OpenIV. These programs allow you to access and modify the game’s files, including WFT models.
On a Mac, you can use a program called Fragmentarium to open WFT files. This program allows you to view and edit the models within the WFT file, as well as make changes to the textures and animations.
Other Methods of Opening WFT Files
In addition to using dedicated programs, there are a few other methods you can use to open WFT files:
- Web Viewer: Some websites provide online viewers that allow you to view WFT files in your browser without downloading any software. However, these viewers may not offer as many features as dedicated programs.
- File Converter: You can use a file converter to transform WFT files into a different format, such as OBJ or FBX. Once converted, you can open the file in a variety of 3D modeling programs.
- Hex Editor: A hex editor allows you to view and modify the raw binary data within a WFT file. This can be useful for making advanced edits or extracting specific information from the file.
File Structure and Contents
WFT files are a proprietary format used in Rockstar Games’ Grand Theft Auto IV (GTA IV) to store vehicle models. They contain 3D mesh data, material definitions, and other related information required to render cars in the game. The file format is comprised of various sections that include header, node hierarchy, vertex buffers, index buffers, and material textures. The header section stores metadata about the file, such as the file version, model name, and number of nodes in the hierarchy. The node hierarchy defines the skeletal structure of the vehicle, including bones, joints, and the relationships between them. Vertex buffers and index buffers contain the geometry and topology of the mesh, respectively. The material textures section references external texture files used to apply visual details to the model.
Import and Export
WFT files are not meant to be directly edited or manipulated by users. However, there are various tools and applications available that allow for importing and exporting WFT files into different formats, such as 3DS Max, Blender, and ZBrush. These tools provide a bridge between the proprietary WFT format and more widely used 3D modeling software. By importing a WFT file into a 3D modeling application, users can make modifications to the model, such as adjusting the geometry, changing the materials, or adding new details. Once the changes are made, the model can be exported back into the WFT format, ready to be used in GTA IV.
