What is a DFF file?

A DFF file contains a three-dimensional model saved in the RenderWare binary stream format. It is used in 3D games that utilize the RenderWare 3 graphics engine, such as the Grand Theft Auto 3 (GTA3) series. DFF files typically store models for humans and vehicles, such as cars, buses, and boats.

More Information

You will most likely only encounter DFF files if you are a GTA3 gamer looking to modify the appearance of players and vehicles in the game.

DFF files are organized into multiple sections that describe the geometry and materials that compose the model. Sections in the DFF file include texture, reflection material, model skins, the behavior of breakable objects, and specular lighting material.

NOTE: While DFF files store models for GTA3 games, textures are saved in .TXD archives and animations are stored in .ANM animation files.

How to open a DFF file

You can open DFF files with Zanoza ZModeler (Windows) to alter RenderWare models. You can also open DFF files with Blender, but you must also have the DragonFF plugin installed.
