If you have dozens of models (e.g., a map conversion project), you need automation.
Recommended Script (for Blender + DragonFF via Python):
import bpy import osinput_dir = "C:/objs/" output_dir = "C:/dffs/" convert obj to dff exclusive
for file in os.listdir(input_dir): if file.endswith(".obj"): bpy.ops.import_scene.obj(filepath=os.path.join(input_dir, file)) bpy.ops.object.select_all(action='SELECT') bpy.ops.export_scene.dff(filepath=os.path.join(output_dir, file.replace(".obj", ".dff")), export_normals=True, export_materials=True, export_vertex_colors=True) bpy.ops.object.select_all(action='SELECT') bpy.ops.object.delete(use_global=False)
Caution: Batch conversion only works reliably if all OBJs share identical material structures and triangulation.
Converting OBJ to DFF exclusively requires strict adherence to triangulation, dummy hierarchy, and normals. Use 3DS Max with Kam’s scripts for legacy stability, or Blender with RW.IO for modern flexibility. Always validate with a DFF viewer before in-game testing. Follow these rules, and your OBJ will become a fully functional RenderWare DFF. If you have dozens of models (e
Result: A clean DFF file with intact normals, multiple materials, and full dummy hierarchy.

For users without access to 3ds Max, the tool DragonFF (available for Blender) provides a robust alternative. Caution: Batch conversion only works reliably if all
