Create a massive abandoned ruined factory dungeon for Minecraft Java Edition 1.20.1, exported as a WorldEdit .schem structure. Make it a full dungeon, not just a building. The structure should be huge, dark, industrial, broken, and highly detailed inside and outside. Theme: A forgotten factory complex that has been abandoned for decades. It should look dangerous, rusted, collapsed, and haunted by old machinery. The outside should have cracked walls, broken windows, collapsed roof sections, smokestacks, pipes, vents, warning signs, rusted metal supports, overgrown vines, rubble piles, exposed wires, broken loading docks, damaged fences, and ruined factory towers.
