Exporting to .ac format using the io_scene_ac3d addon files

Postby skipper0802 » Mon Aug 06, 2018 7:56 pm

Greetings All,

I'm trying to modify a Blender file object (aircraft instrument) then export to an .ac file for use in Flightgear. Error script follows below. I've enabled the ac3d folder contents in separate attempts for the directory folders as such:

    /program files/blender foundation/blender/2.79/scripts/addons
      /program files/blender foundation/blender/2.79/scripts/addons_contrib

      I also tried enabling the addon within the Supported Level: Testing area

        Hardware: EliteBook 8770W laptop, Windows 10 Home, 10.0.17134, x64. Intel i7-3520M, 8GB ram, AMD Firepro M4000 1GB ram. 1920x1080x60 Hertz.
          Blender software: v2.79
            io_scene_ac3d folder contents: _ init _.py, AC3D.py, export_ac3d.py, import_ac3d.py

          When I try to export my Blender file to an .ac file format, I receive the following red-lined errors:

            Traceback (most recent call last):

              File "C:\Program Files\Blender Foundation\Blender\2.79\scripts\addons\io_scene_ac3d\__init__.py", line 266, in execute export_ac3d.ExportAC3D(self, context, **keywords)

                            AttributeError: 'NoneType' object has no attribute 'image'

                              location: <unknown location>:-1

                              I'm not familiar enough with the Python/C++ language to determine the cause of the error. Can anyone provide me some hints on how to fix/correct the export feature? Is this export error within Blender settings/config or is the error within the .py import-export files? (The content of this post is also listed on the Blender Stack Exchange for more exposure.)

                              Thanks in advance, Eric

                              This is the error.

                              Probably, you didn't assign a texture to an object or the plugin is looking for texture images in another directory. Check this thread: viewtopic.php?f=4&t=28551

                              Thanks ludomotico...checking it out...


                              Post-edit: the cause of the problem was the path (location) error. the new instrument is now rendering in the cockpit of my PC-21 :mrgreen:

                              Thanks very much!
