Swapping VZF heads on the same avatar

[vr_boyko]

Hi there,

I was wondering -- how do you "swap" one .vzf head with another on the same avatar?

For example, I have this neutral.vzf head for an avatar, and if I want his face to change to be happy.vzf -- how do I do so without having the head just superimpose itself onto the old neutral.vzf head?

(I defined a function in my class like this:

def face(self, facename):
self.head = viz.add(facename)
self.agent.face(self.head)
)
