Pretty interesting , then I assume that the creaores in here will have allot of work registring there work :-)  and actually was my first argument that before claiming it a complete creaton of theres it should be done this way , correct me if i am wrong , but if they would do so ,  the the releases could not flood like they do right not , it probably would slow down the publications considerably !!

 then also , well i assume that the creator will have to be able to prove on registring a product that this one is in no case a derrivitive work , is it, then they will have to attatch each written permission to the copyright.

do this also to protect the consumer ( Buyer ) , if not then it would be fraud causing the enduser also to get in troubble by using and publishing renders of derivitive non approved work!! 

well , if the creator really would be as senceare then the prices would rise to the Sky like grafic products that are licenced , there we recognize the licence on the pricing as they are considerably higher and not to compair with poser products.

especially considering that if a Creator has a pricig of 10$ the effective gain would be probably 7$ or 5$ the store gets the rest.
