There is a constant horizon color transition dark layer at all hours. You can just make it out in the dark. Here are screen captures of early morning and mid day.
Fixed for the next patch
Does this also effect the "dark" water color seen when looking at close proximity seas? These areas of very dark waters lose whatever reflective properties that are so very nice in AH2 and pond water. This causes an "un natural" loss in depth perception / or distance from water when flying at low altitudes. Basically, it reminds me of the difficulties in flying AH2 with terrain detail off.
In a main arena environment, this may not go over so well, if it is seen as a step backwards. I don't mean this to be harsh criticism, especially since I have seen how much effort that you are putting into that particular area, with much improvement noticed. Also, I am aware that you stated in the previous patch that you were not satisfied with the water (I assumed you mean lighting/ post-lighting).
Perhaps the inability to set underwater terrain texture is providing the challenge, I don't know
Anyhow, sun and moon lit reflections, the rolling surf and the ability to see torpedoes running underwater blew me away!
I just hope this is not the price to be paid.
