You can report bugs with the addon here, but please include problematic. The default settings are: Forward -Z and Up Y. Orientation: The default settings in the plugin correspond to the FlightGear coordinate system (-X forward and Z up, also see: Howto:3D_Aircraft_Models).Notice that since AC3D only support 1 texture per object, if multiple textures are attached to an object in Blender the last of the textures that has any data, if any, will be the one that get exported, but it will still warn about the missing data in the others, so take care. Pull down the top bar to see if there was any, they will be orange lines. The exporter will not fail if it tries to save a texture without data, instead it will issue warnings.The importer will not fail if it does not locate a texture, instead it will issue warnings.If you want to export/import a color for those, import/export options gives you capability to choose to use Blenders mirror color for that. Be aware that Blender only has greyscale for emission and ambient colors.

In such cases blender addon scripts are placed in: $HOME/.config/blender/X.YY/scripts/addons/ (where X.YY is blender version, for example 2.82). In recent Ubuntu versions blender is distributed as a snap image. For for example Ubuntu 14.04LTS/Blender 2.79b it is: /usr/share/blender/scripts/addons/. If you wonder where to put the scripts you could open blender's user preferences ( Ctrl+ Alt+ U, or File > User Preferences) tick for example Import/Export and extent the information concerning an existing script.Hand editing the materials section of the exported AC3D file might fix this. The final model might display color mismatches (Texture color vs Material color) when viewed in Flightgear.An example plane that will look very different if this is not done is the FGAddon aircraft ASK-13, notice the wingtips. To see textured surfaces as they will be shown in FlightGear, go into the material texture and set the blend type to Multiply instead of the default Mix (the importer will also do this automatically).Alternatively set textured solid in solid view. Inside Blender when you want to see the textures, be sure to set the shader to GLSL (or for 2.7+ just set view mode to materials).Before you export make sure to exit Edit Mode or some of your last changes won't be exported.


It has been forked from its original to provide support for Blender 2.8. The prominent add-on for using AC3D files in Blender is called Blender-AC3D. Importing and exporting AC3D files Note Modern versions of Blender (2.5+) require an add-on to work with AC3D (.
