Stay well clear of the Shamms Mortier's so called Poser Handbook. It is the worst book I have ever had the misfortune to pay out for. I no longer have it since I binned it after a flick through. The Images used are something you would expect from poser 1 not 5. The learning is non existent. BTW worldbuilder 3.X is free on the front of Digit this month.
