Ok let me explain those reflections. They are not vivid and glassy like in BW1, or lesser marked but always present like you see in BW2. In BW3, close to the shores, they are visible just in some circumstances, like the scroll view used by the player (closer the view is, better rendered and bigger are the reflections for example). Reflections are invisible in case of:
A) Open sea, no shores nearby (if map is Q rotated, you will see just small sunlight reflections on the water surface at direction of the sun. Nothing else)
B) Map rotation used as anticipated in point B
C) Shores located at N and covered by the position. Example, my first post first picture delta of Nile, no reflections at the top. But this thing changes whenever you rotate the view pressing E or Q
D) reflections do not share or influence the wave movement. They are both indipendent the one from the other.
This is how it works for now, i have to study the architecture used by CA in this game. It's just a day i learnt how to edit Rome 2. As i said, it is a work in progress. This is my first mod since Med2. Result is very very good in my opinion
