This model looks so realistic, because it attracts the force of gravity.
The street, the footpath, the kerb are embedded in the base board. In my routes all tracks, roads, fences and other spline objects are visibly "flying" above the ground, as they were made of ribbon. I just can't dig them in to the ground level, without manipulating each spline separately. It looks like TRAINZ cannot blend splines with the base board to give it a natural look.
How much time does it take to achieve such great effect?
