Hi,
When you attach a head to an avatar Vizard will internally override its rotations and translations in order to keep it attached to the avatar. If you want to rotate the head, simply rotate the head bone of the avatar and it will transfer over to the head model. Sample code:
Code:
headbone = male.getbone('skel_Head')
#Lock the head bone so that we can manually control it
headbone.lock()
#Rotate the head bone
headbone.rotate(0,1,0,90)
I'm not sure if this is usefull to what you are doing but there is an avatar action that will rotate the head to a certain orientation.
