Hiya,
I assumed it was the merging, I am not a modder but am messing and wetting my toes paddling into stuff so to speak
If there are a limited number of "bands" or Linear lines allowed to create the sky top to bottom so to speak, I very much doubt a smoother better blended sky could be got
But if there are no limited or a least layers that can be released then well in the future we may have a very smooth blended sky area and even moreso a finer blended under water view
May try and look into it
Have Fun
Ciao
