Sharp-edged blending of landscape textures

[ThousandsAreSailing]

Hello! I was just wondering if it's possible to smoothen out these angular transitions between different landscape textures, an ini-tweak perhaps?

I know that the ground mesh is made out of triangles and I have noticed this texture bug before, but never this bad. :yucky:

It's most visible where bright and dark textures meet and occurs in loaded cells without SSELODGen enabled.
