Pardon me for pointing this out, but there's nothing in the images to suggest that the Doctor is accepting that the "official" standard in Poser 3, 4 and 5 is 8 feet (96 inches) per unit, or any acknowlegement that his own system is at odds with the official standard, or for that matter that that the 8.6 foot system was based on an error that was acknowleged and (partially) corrected to the 8 foot system in SR1. You are free to adopt whatever standard you wish but Dr Geep is clearly and implying that the official scales have changed and this is a deliberate falshood. IMO this is purely about saving face and refusing to admit that he was initially incorrect in his assertion that the 100 inch scale was "official". His purpose in this tutorial is to confuse his readers, and as such he is doing a disservice to the Poser community. Bill
