i tested it with both GWX and NYGM and in both cases there is a problem with the sun, it is very small and moving too fast on the sky , i hope we can fix this because i really liked the look of the water and the variance in colors . I also tried some older version, V84 and its the same thing .
I also have this SH5 water mod :

That one doesnt have any sun issues for me .
