Problems of Exporting Cars to DFF

When I export a DFF I got an error:

  File "C:\Users\jonat\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\DragonFF-master\gui\dff_ot.py", line 134, in execute

    surface[0] = mat.dff.col_mat_index
AttributeError: 'NoneType' object has no attribute 'dff'

Apparently all options are OK, so I don't know what it could be

There seems to be a material in one of the collision models that was not created with DragonFF installed.

Hmm, thanks for the help, but, now I got this:

Here is the log:
gta_sa.exe_2024-01-19_00-39-41.log

Could the problem be resolved in the same way as indicated in the message on the screen? but with dragonff, or is there another way?

Edit: Doing what was indicated there didn't help much, importing and exporting
