Landscape Auto Material

I was wondering if someone figured out a way to deal with ugly tiling in the distance like on my mountains in this screen?

I was expecting a built-in material function like a transition to flat color but it doesn’t seem to exist - any pointers?

EDIT:

If you got questions you can always ask them directly at , I asked mine yesterday and I already got an answer.

The answer is apparently to play with Side_MacroScale in the material instance parameters.
