I use Debian Squeeze 6.01 64bit. I’ve spent good hours to install MBDyn add-on which comes with two python script files. Blender 2.58a won’t install it at all. I tried to use [Install add-on]. I copied the script files at ~/.blender/scripts/addons or blender’s default add-on directory.
Just for curiosity I installed Blender 2.49 version. I can see MBDyn menu now when I choose the script window. But, it’s way too slow compared to 2.58a one.
Is there big change from 2.49 to 2.5x the way Blender handles python scripts?
