Never trust a one-click conversion. Always test:

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.

Replace input.obj with your OBJ file name and output.dff with the desired DFF file name.

A common complaint is that converting to an intermediate format (such as 3DS) destroys smoothing groups, causing visible seams on the model. Import the OBJ directly into 3ds Max and export directly to DFF using Kam's scripts, avoiding any intermediate format that strips smoothing data. The Kam's scripts also include a "Mesh Fix" checkbox that can correct polygon mixing issues after export.

If you have access to , use GIMS Evo for the best results. If you are a beginner or want a free standalone tool, use ZModeler 2 . If you are familiar with Blender, use DragonFF .

Ran the converter again.
