Custom head on HD Complete Character

[Frank Verberne]

While doing some testing on the HD Complete Character provided with Vizard 4, I noticed that the head and neck are different from the Complete Characters body. The main difference is the neck: it seems that for HD CC's, the head and neck are one object, and that the neck for the HD CC's is much wider than that of CC's. Is it possible to use custom heads (as the one provided with Vizard, but also FaceGen heads) with HD CC's without having to model the specific neck model as well? I've also seen on the pictures of all the HD CC's that the necks seen to differ over different HD CC's. If this is the case, would one solution for one HD CC not work for others?

import viz
viz.go()

male = viz.addAvatar('vcc_male2.cfg',pos=[.3,.3,2],euler=[180,0,0])
face = viz.add('biohead_talk.vzf')
face2 = viz.add('biohead_talk.vzf')
male.setFace(face,'Bip01 Head','Bip01 Neck')

female = viz.addAvatar('vcc_female.cfg', pos=[-.3,.3,2],euler=[180,0,0])
female.setFace(face2,'Bip01 Head','Bip01 Neck')
