![]() ![]() An AC3D object is a collection of surfaces.ĪC3D can load and save a wide variety of 3D file formats but primarily uses its own. An AC3D surface can be a polygon, polygon-outline or line. Unlike some other 3D software, AC3D refers to 'surfaces' rather than 'polygons'. In 2005, a Mac OS X version of AC3D was released.ĪC3D's modeling is polygon/subdivision-surface based. ![]() They decided to keep the name AC3D for the software. In 2002, Inivis Limited purchased the full intellectual property rights to AC3D and continues to develop and market the software. A Microsoft Windows port followed when the X11 interface was dropped in favor of the portable Tcl/Tk scripting library. At that time, the user interface was implemented using X11/ Motif.Ī Linux port was released onto the internet in 1994 (the GL graphics were replaced with OpenGL). Once the add-on is installed, AC3D models can be imported in the same manner as any other model foramat into Blender by using the File > Import > AC3D (.ac) dialog.Initially developed on the Amiga, the code was then ported to Silicon Graphics workstations which used the GL graphics library. Note If you do not see the option for AC3D (.ac) under File > Import, your add-on is either not installed, not enabled, or not working correctly. See Working with FlightGear models in Blender for the main article about this subject. 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/.
