I agree completely BurrMan; rendering Avatar might be a bit beyond Keyshot ;-)

It really is horses for courses. That doesn't surprise me. What surprises me is that there is so little software that is aimed at interested beginners. After all, by the very nature of things, there are far more people who might be somewhat interested in 3D modelling and rendering than people who are very interested in 3D modelling and rendering, just as there are far more people who are casually interested in cooking than there are people who are interested in taking professional cooking qualifications. By analogy the rendering software market at the moment requires you to sign up for a 20-week course when all you want to do is learn how to throw together a chili for the Monday night game. No doubt this will change.
