Texturing an avatar head

[VAmanda]

Hi,

I'm trying to change the texture on an avatar's head, and when I do so it's just showing up black, even when I use the original texture. My code is basically as follows:

face = male.face('myface.vzf')
texture = viz.add('mytexture.jpg')
face.texture(texture)

Event when mytexture is the original texture on myface, it still shows up as black after this code. Do I need to change something about the texture or the head? Thanks.
