Converting a Wavefront file to a RenderWare DFF format is a common task for modding older games, most notably Grand Theft Auto: San Andreas (GTA SA) and Vice City . Core Tools Required

For exported models, the armature needs to be parented to the model (not the other way around)

Select the zip file, enable the add-on, and save your preferences. Step 3: Import the OBJ into Blender Go to File > Import > Wavefront (.obj) . Locate your file and bring it into the scene.

Since the game engine cannot interpret raw OBJ files, you must convert them into a DFF format that it understands. This process is often called "modeling for GTA." Tools Required for Converting OBJ to DFF

Open the DFF in a hex editor or RWAnalyze to verify the texture string exactly matches the image names inside your TXD file. Scale and rotation were not applied before conversion.

Texture handling: When using DragonFF, textures need to be handled separately. Find the textures in Blender's Material Properties and ensure they have the same name as in your TXD file. The TXD should have the same name as the DFF file. Import textures using TXD Workshop or Magic.TXD.

DFF files, by contrast, are , hierarchically structured and heavily optimized for fast loading and rendering inside the RenderWare graphics engine. They contain not only the visible mesh but also material definitions, frame hierarchies, collision data (in older implementations) and sometimes per‑vertex lighting information. Converting an OBJ to DFF is therefore not just a matter of changing a file extension — you must transform a generic, text‑based model into a proprietary, structured binary asset that the game expects.

Select the correct version of the engine (e.g., GTA SA uses RenderWare 3.6.0.3).

To tie everything together, here is a practical example of converting a custom vehicle model from OBJ to a fully game-ready DFF with textures and collision.
