The tutorial about how to create a new base.mesh for MakeHuman, http://www.dedalo-3d.com/index.php?filename=SXCOL/makehuman/articles/make_a_makesphere.html, says:
in the gui.py file, that is in your text window. change IniName = “makehuman.ini” to your new ini name (for instance IniName = “makesphere.ini”)
Save your blend file
But don’t have a IniName = “makehuman.ini” in the Gui.py text window. :-?
