StorkNest thanks for giving me a starting point on water in Trainz. I assume that I assumed incorrectly
Having done some 3d stuff as a hobbiest, one could make water appear to move by using animation. The animation could consist of something as simple as modifying a 2d flat plane and have its deformation influence the water map.
I was guessing that the same sort of animation would be true with waterfall movement in Trainz. That's why I would have liked to see the source files for a waterfall in trainz, to see the inner workings of how to acheive it.
