Stony Cliffs Are Cool — Guide

How the swap is decided

Only dirt that is already part of a steep, exposed face is eligible, and only where stone is already present nearby. That condition is what keeps ordinary countryside untouched - a rolling meadow has no exposed vertical faces, so nothing there qualifies.

The grass layer on top is preserved, so from above the land still looks green. The change is visible from the side, on the cut.

Scope

Every overworld biome is covered, so the effect is driven by how steep the ground is rather than which biome you are standing in. Ridges, plateau edges, valley walls and lake rims pick it up; flat terrain naturally shows little because it has few steep faces.

Nothing is added to the world - no blocks, items, mobs, structures or recipes - and no terrain height or shape is altered.

Existing worlds

The rule is applied at generation time. Land already generated keeps its original appearance, so installing this into a world in progress will not alter the ground around anything you have built.

New territory generates with stone faces from the moment it is installed, and the world remains perfectly playable if it is later removed.

What to expect visually

This is a subtle, world-wide change rather than a set-piece. Individual screenshots show less of it than travelling does; the clearest way to see it is to compare the same slope with and without it, where the dirt wall becomes a banded rock face.

Terraced hill country shows it best, since those slopes are made almost entirely of short vertical cuts.
