These images and actual real life nakid women are available to 3D developers for miniscule cost. Levious gives unlimited royalty free for $14USD/month. I paid models $10-$25USD per hour and sometimes per shoot. Some were exotic dancers who offered sexual services in addition for only double the rate. I no longer higher model since I am poor now and have no affiliation as an instructor to protect me from false alligations (I used to video tape all sessions for legal reasons).
