Is it a new map design? New biome? Map of structure generation? The world is changing... This was on the Facebook and Instagram page...
Well... its probably a new part of the map... I don't think they'd make such a big deal out of a block or structure (unless it was a major structure).
Edit: Taking a closer look, its appears to be either clouds or snow covered in cracks...
Thats a texture of a stone laying down in the meadow fields in valinor for sure!
New Chalk texture?
Texture seems good...
What do you think?
