hmmm...maybe the language. but which "understanding of water" do you mean?
fact is: we have no real bump controller in the scene dat. its a fake "bump" only for dark/bright areas on the water. not a reflection. normal bump maps are for rendering light reflections, this one in scene.dat works different.
i tested everything the scene.dat lets us change. result is better reflections on the water, with a slightly more rough looking surface as shown in this thread.
PROBLEM and LIMITS
when reaching a real good looking reflecting surface nearby the boat, it looks odd in the distance, cause there is no accessable parameter for changing the render distance of the water surface effects. so the water shimmers and blinks heavily in the distance -> ugly.
---
so, conclusion for a better surface of the water is: getting a new foam texture added, used by water with wave height "0-2 -> normal state" or linked to different wind conditions EVEN UNDER 6, where some foam is beeing created. this texture should contain water surface noise and be defined as "bumpmap" -> giving us better, rough looking reflections -> as bumpmaps seem to work nicely on the u-boat hull. same should then work on the water surface, right? or am i wrong?
