Moreover, the heart of this entire tutorial involves using the rigging of erogenesis' dress mannequin, which he created specifically so users of PE can home-brew their own converted garments. It requires a user to purchase his product. He allowed me to create a freebie for people who own the mannequin to use for Pauline. In this case, all I'm doing is showing people how to change the joint zones and apply the morphs brush. If people want to repurpose other rigging that they have bought for other personal projects, that's fair use.
