Hi systemshock. Put this at the end of your mood file,,,,,\SetSwitchIntensity [switch= visemes f0= 1.600000] You should find that she mouths the words a little better. Play with the settings to see what you think is better. Change f0 between 1.600000 & 2.000000 no higher or mouth goes haywire.
A couple of years ago i had a go at changing a male model to female which didn't work real good. Finally i think it is very close to what i was aiming for. The reason being that the facial features are a lot better in the male than the female figures.
The first pic is a before & after pic.
The second pic is a comparison of the now 2 female figures. Same skin & hair on both, only difference is the one on left is original female & one on right is altered male.
