I'd need more info on the subject, to understand what you actually wanted. Like are you trying to copy it but want a different color or something? If you just want a copy, just change zero derive it, meaning derive it and submit it without changes. People do that all the time and you can not get into trouble for it. Technically any product open for derive, and all its textures are free to copy, if you derive from it, and its legal. Its not ethical, and some devs might get mad, but it is legal as per IMVU's TOS, that no one ever reads lol.
