Iron Cannonballs and Shot Stack

Cast-iron round shot for a 6-pounder gun, 9.3 cm across: right beside the guns of a fort or battery (the Alamo in 1836 and the Texas Revolution), on a ship's deck, in an arsenal yard or a museum display.

The stack is a square pyramid of 30 balls (4 x 4, 3 x 3, 2 x 2 and 1) standing on the ground, each ball resting in the hollow of the four below. The iron is rough and dark with fine casting pits and patches of rust.

Two meshes: the stack (CannonballStack, 27,360 triangles, 2048 px maps, 38 x 38 cm and 30 cm tall) and a single ball to scatter or load (IronCannonball, 912 triangles, 1024 px maps). Each is a single LOD with one PBR material (colour and normal maps; the GLB also carries its roughness map), real-world scale with its origin on the floor. Static meshes: FBX for Unreal and Unity and GLB for Godot, three.js and glTF importers, with PNG textures.
