Admin2, I don't know if there are may Vue users at turbosquid, I may be wrong, but TSquid is 99% about 3DS Max, and even if there are Max/Vue xStream users there, if they are to buy a Vue scene, it better be something they can't do themselves, by this I mean complete environments with terrains, good materials, advanced ecosystems and atmospheres.
I do NOT mean your scene is poor, but maybe not useful to professionnals.
You should think about www.cornucopia3d.com, a dedicated Vue community where you can buy/sell anything Vue ( provided you don't infringe any copyright of course). There you can find professionnals and hobbyists alike, and the latter may be more interested in your products than pros.
