Ruins Generator turns time loose on your scenes. Select any building you modeled and press Ruinify: its top breaks away in a ragged line, holes are punched through the walls, the windows lose their glass, rubble piles up where the stone fell, and moss, grime, ivy and grass creep over what is left. It is non-destructive, so a Decay slider and a seed change the ruin live, and Remove gives your original building back.

Or build a ruin from scratch. 31 ready-made ruins modeled on real places cover the whole history of building: Greek and Roman temples, a tholos, a forum colonnade, a triumphal arch, an amphitheatre, a hillside theatre, an aqueduct and villa foundations; an Egyptian hypostyle hall, a ziggurat, Maya pyramids, a Khmer temple gripped by tree roots and a brick stupa; a Gothic abbey, a Romanesque church, a castle keep, an Irish round tower and an abandoned croft; a bombed brick block, a collapsed concrete frame with rebar and an old factory; a henge, stone circles, stone rows, a dolmen and two fantasy shrines.

Every ruin is built block by block in real meters. Walls break along their courses, columns fall drum by drum and lie in rows the way earthquakes leave them, beams only survive where both columns still stand, and the rubble settles in physically plausible mounds at the foot of the walls.

Ruinify any building
Select a building, press Ruinify and drag Decay: the top breaks, holes open, rubble piles up and ivy climbs, live and non-destructive.

31 real ruins
Greek and Roman temples, pyramids, a Khmer root temple, abbeys, castles, bombed blocks, concrete frames, henges and fantasy shrines.

Decay from whole to stump
One slider takes a castle keep from a few missing stones to a broken shell, with the fallen blocks piling up below.

Nature takes it back
Moss, ivy, vines and grass creep over a Romanesque church as the Nature sliders go up, and back again.
