MHX2 is not bundled with MakeHuman, but is hosted separately at https://bitbucket.org/Diffeomorphic/mhx2-makehuman-exchange. To download the repository as a zip file, go to https://bitbucket.org/Diffeomorphic/mhx2-makehuman-exchange/downloads.
General method that works for both stable and unstable versions:
- Unzip the .zip file to any place on your computer.
- Move, copy or link the folder 9_export_mhx2 to the MakeHuman plugins directory. On some versions of Linux it may be necessary to change file permissions with the command: sudo chmod a+rx /usr/share/makehuman/plugins/9_export_mhx2
- Move, copy or link the folder import_runtime_mhx2 to the addons destination directory where Blender will look for user-defined add-ons. Depending on the OS, this may be:
- Windows 7: C:\Users\%username%\AppData\Roaming\Blender Foundation\Blender\2.6x\scripts\addons
- Windows XP: C:\Documents and Settings\%username%\Application Data\Blender Foundation\Blender\2.6x\scripts\addons
- Vista: C:\Program Files\Blender Foundation\Blender\%blenderversion%\scripts\addons (this is valid at least for blender 2.69)
- Linux: /home/$user/.blender/$version/scripts/addons
For the stable version, Joel Palmius pointed out that there is a simpler way to copy the importer to the right place.
Start Blender and navigate to the add-ons tab (File > User Preferences > Add-ons). Select Install from File…
Navigate to the .zip file, and press Install from File… . Blender now unzips the repository and copies the files to the right place, for every supported operating system.
Enable the add-on by selecting the checkbox at the upper right, next to the running man.
The MHX2 import is now available under the MHX2 Runtime tab.
