Yes.

Just use the extractor to convert the DFF files into obj. That extractor is in the 1st post I think. You can find it in the Xentax web too.

Select a file with the extractor and click the obj type you want (there are 3 because not all dff can be converted as the same method).

I didn't tried all files but only some weapons, some heads and 3 or 4 dogis can be extracted correctly.

can you tell me how you make the models? which programs i need

you did a really good job with those models.
