A standalone, lightweight modeler specifically designed for GTA modding. It can import OBJ files natively and export directly to DFF. ZModeler is the easiest path for beginners.
For users who prefer open-source software, DragonFF is a plugin for Blender.
Before diving into the tools, it is important to understand the limitation of the OBJ format: convert obj to dff
The Catch: When you convert an OBJ to DFF, you are creating a static DFF. If you are importing a player character or a vehicle that requires moving parts (doors, wheels, steering), simply converting an OBJ won't work—you will need to rig it in Blender/Max first using a skeleton. For static objects (buildings, props), this conversion is straightforward.
Blender is the gold standard for DFF modding because the community has developed powerful add-ons. Export:
A diagnostic tool. Use this to inspect an existing DFF to see its hierarchy, atom structure, and bone assignments. Never convert without referencing a working original.
