addface problem

[dan12345]

Hello
i tried creating a face using the procedure explained in the tutorial
(3dmenow - 3dmax -peoplemaker - vizard)
i managed to create a seemingly normal *.vzf file - in the 3d subwindow
in vizard, it looks just fine
the problem is that after executing the following code

import viz
male = viz.add('resources/characters/NudeMale8/nude08_m_highpoly.cfg')
face = viz.addFace( 'resources/faces/shahar.vzf' )
male.setFace( face, 'Bip01 Head', 'Bip01 Neck' )
viz.go()

then instead of having the original face changed , i just get a giant static
distorted background image of the face.

where did i go wrong?
