I am hoping fot the day to come that Xfrog would deevlope something like "Solid Growth" (I have already indicated that to them) and a rendering engine of their own. From my understanding, Xfrog is still improving to provide what user hopes to have for the windo version. The SGI version has lots more stuff that the recently develope Win version do not. Well, time will tell but what I really like is that Vue, and the rest of 3d program like Poser, Xfrog, etc...all can work in support of each other. This is really wonderful! Bill
