At one point I had everything working, I could import mhx models and I could use the mocap tool. Then one day Blender would not recognize mhx imports or any of the MakeHuman scripts bundled with MakeHuman that I previously installed.
I'm using a MakeHuman nightly build from 1/10/2011 and Blender version 2.56a Beta under Windows XP sp3. More recent versions of MakeHuman nightly build have the same problem.
I uninstalled and reinstalled Blender and followed the MakeHuman document describing how to install the MakeHuman scripts into Blender. None of the scripts would show up on the Users Preferences, Add-Ons panel. I tried to manually install them by using the "Install Add-On..." button on the Add-Ons panel but was told the file already existed. But still nothing shows up in the Add-Ons list. In the Blender "File, Import" there is no option to import mhx models. I know this sounds confusing, I'm very confused.
To make things even more confusing when I uninstalled Blender and did a clean reinstall, Blender could still remember other import scripts that I had previously added that were not in the basic install. If I unselect or select other scripts then completely uninstalled and reinstalled Blender those selections show up in the newly installed Blender. To my knowledge Blender is not suppose to use the Windows registry and I checked to make use all Blender files were deleted. So there must be an undocumented file that I missed somewhere. The Blender console window has no error messages.
This is probably not a MakeHuman problem at all but it has me completely stumped, so if anyone can help or point me in the right direction I would greatly appreciate it.
