Логово дракона с грудой золота: черновая сцена в Blender

Build a moody 3D dragon lair environment in Blender, scripted with Python so it can be rerun. The set is a large underground hall of weathered stone brick walls, square columns, stairs and rough cave rock overhead. Scatter props across the floor: skeleton bones, broken slabs, clay urns and iron braziers with live flames. In one corner heap a huge hoard of thousands of individual gold coins with a chalice, a sword and other treasure on top. Light the scene almost entirely with warm amber firelight and small glows, leaving deep shadows in the corners and a hint of a bright opening in the distance. Use physically based materials, soft depth of field and a slight film grain. Provide several camera angles: a wide hall view, a stair view looking down into the hall, and a close macro shot of the coins. Deliver the .py script plus rendered stills. Done means the hall reads clearly as a dragon's treasure room and the coin pile catches highlights.
