1 I usually have a figure loaded to start with but that figure is really there just to "take" the face room face and texture.

2 I have found that it is better to only adjust the front view to get that looking right, because when you try adjusting the side view it badly distorts the texture for the front view.

3 You do only move the dots but most of the lines have handles that you can move to make the curve more or less, so that it fits better.

4 The best way to apply the face is to click on apply shape only and then click on apply texture only, in poser 5 apply to figure makes the head morphs stop working but even in poser 6 it is probably the best way to do it as I said earlier (Not using apply to figure).   Once you do that you might have to set the face morph and the eyes morphs to 1.
