use a makeHuman nightly build…
Use the Blender build from Blender.org
export the .mhx from MakeHuman with “rigify” checked.
Open Blender go to the preferences and enable “import export mhx” makehuman
Also enable Rigify…
Import the mhx model, import the model that has 25
when you import the mhx in the operator panel check “enforce version” (leave it on graphicall")
If the model imports correctly you should see a hoop/ring around his torso, and a hoop/ring with arrows around his waiste.
Ok… box select all of this then it will turn blue, and set “with automatic weights”
but you are right, you eill get all kinds of errors if you try to use a MakeHuman with a current graphicall build
(use blender build on blender.org Windows 64bit version works. if you follow the steps i gave.)
