THE PROBLEM
Ultra Dynamic Sky is an amazing solution for beautiful sky and weather system, but natively it doesn’t work properly with the water system.
Check the video below and see how sunset times with cloudy sky give a very weird water reflection that is not realistic at all:
SOLUTION
I had to change the Lighting Channel from 0 to 1 in UDS and change all items in the scene to be on the same channel 1, except for the Water body Ocean that stays in channel 0.
To do that simply search for Light Chan in the Details panel.
