Export error

[SimplyCEO]

I got this error while exporting my model:

Python: Traceback (most recent call last):
  File "/home/kanux/.config/blender/3.1/scripts/addons/gta/gui.py", line 140, in execute
    dff_exporter.export_dff(

    data = Sections.write_chunk(Clump,
TypeError: Sections.write_chunk() takes 2 positional arguments but 3 were given

So I decided to test it with a original model, that also gave me the same error. I deleted the entire generic hierarchy just to be sure and gave the same error again.

OS: Arch Linux Python: 3.10.4 Blender: 3.1.2

It doesn't seem to be the latest version. Get the latest master branch (or new_export branch) version and try again.

[SimplyCEO]

The version of DragonFF installed is v0.1.1 and all the packages in my system are up-to-date.

One thing that I noticed is that indeed this function is receiving 1 more argument.

def write_chunk(data, type):

Seen in dff.py, line 206.

data = Sections.write_chunk(Clump, pack("<I", len(self.atomic_list)), types["Clump"])

Is the only call in the file that gives 3 arguments to write_chunk function.

v0.1.1 is 3 years old. The releases aren't being updated since there's no need for them. I realise that the readme mentions the releases, but you should ideally use the master branch (it doesn't contain unstable code).

Direct link: https://github.com/Parik27/DragonFF/archive/refs/heads/master.zip https://github.com/Parik27/DragonFF/archive/refs/heads/new-export.zip (if you experience issues with normals/shading exports)

[SimplyCEO]

Both give the same error, even removing manually the camera and light.

[Parik27]

Can you share the full stack trace when using the version from either of the links and possibly the blend file you're using to export.

The solution would be to change write_chunk to just write. Seems to have been an oversight while writing that code and this section of the code wasn't tested before because of the rare RW version.

I already tried it, but got the following:

    _data = pack(packer, *data)
struct.error: pack expected 3 items for packing (got 4)

location: <unknown location>:-1

I tried to follow this pack function, but couldn't find.

[SimplyCEO]

Tried to catch the error and it gave me the following: packer - <3I data - b'\x18\x00\x00\x00' Apparently data gets 3 NULLs instead of 2

[SimplyCEO]

I manually sent the *data packet as 24, 0, 0 instead of 24, 0, 0, 0 and it exported. But in order to import back, it gave me a animation error. Viewing in DFF Viewer seems to show eveything well. While importing it to the gta3.img file crashes the game.

This issue is fixed in the typing branch
