With time, I wish MSFS 2020 could calculate the fetch over open water. It is rather unrealistic to see big waves on a lee shore. The waves are proportional to the distance over the water the wind can blow. This is important if you fly a seaplane because you will always try to land on a lee shore, where there are few waves.
How to do it ? I have made a vessel simulator using Unity. It provides a routine that calculates the distance to an object. This is done for the “shooting” games. I made the sea and the land as two different objects and, with that routine, I could, for example, simulate an echo sounder and even, a radar, on the distance to the “ground” object.
The same could be done for MSFS 2020. I know, there is only one seaplane as it is today, but more will come certainly with time. How can we suggest that idea to the developper of the simulator ?
