I reverted back to my original setup with MEPv3 and the water mod loaded on top of it (via JGSME). This is without the Flat Sun fix. The trade off is the distance (8km-10km) of the horizon. Using the water mod alone works well, however, the fog/distance is not very good. That's using the 16km or 20km versions. If I load the flat sun fix on top of all of it...then I get my 20km distance (no fog) and I can see ships in the distant horizon which is much, much better. The sad part is, in doing that (using the flat sun fix last) then it reverts to the MEPv3 ENV colors.
Here's the difference I see:
Using MEPv3 including it's patch and Flat Sun Fix gives you a very good environment i.e. weather, horizon differences. However, the colors (water/sky) do not, in my opinion coincide with actual real life environment as does the SH5 water mod. The water seems to stay too blue even in darker overcast skies.
Using Rik007 SH5 water mod alone gives you fantastic water/sky colors and very realistic ocean movements, but...not so good horizon/fog distance. The sky/sun reflections on the water DO coincide in basically all weather environments and then add the wave/ocean movements...and you have (IMO) a pretty good ocean environment.
The water mod changes the ENV files such as the ENV Colors and Sky Colors including adding new cloud TGA files and a edited scene.dat
If you have the Silent 3ditor and open the EnvColors_Atl.dat in the water mod, all of the parameters are there. This is where I wish I had 2 monitors to do comparisons between the Mep's and the water mods' EnvColor_Atl.dat files.
Believe me...It is not my intention to critique Makman's and Rik007's work. Both mods are very impressive and I do appreciate their hard work and contribution to the SHIII community. This is a clear case of when 2 great works collide and could become a very good mod in itself if they were combined together to make a great Environment package. Meanwhile, I will continue to dabble. Who knows, maybe I'll find the magic bullet. I am not as near as good with these edits as the modders here have shown, but I can at least try. Kudos

to these mod designers, their work is indeed "hard" and sometimes under appreciated.
