Selling the character is just fine and legal. When selling it you arn't including the actual geometry only a cr2 file or a pcf file which only records the changes made. the actual obj file isn't included. As far as the morphs go Trav created them...he put his time and effort into making them. if someone takes them and alters his work..no mater how you look at it it's his work being sold in someone elses product. If he turned around and said use them freely for whatever you want commercial or non then that's fine but he didn't. He clearly stated on his site that they were for use in noncommercial work (characters not art) only. If someone wanted to use them for commercial purposes all they had to do was ask. Plain and simple.
