I agree with Jochen and Otakar about the short pieces and the water. The first was a choice to be able to show different types of features of TG3. I too would have liked a longer video with smoother transitions and longer shots, but hey, rendering costs money! A lot. And that was also the problem with the water. We had to take severe measures to get at least a little running water, and due to render time per frame, we even had to skip transparency. It's all a matter of time and money, unfortunately.
