A two metre armoury wall bay with a steel security door in it: a braced leaf on two hinge sets with a lever handle and a lock escutcheon, in a proud steel frame. Dimensions 2.000 x 2.604 x 0.180 m (X x Y x Z). Modular piece: the origin is the centre of the wall foot on the two metre grid line; metre units, +Y up, muzzle and point toward +Z. Named pivots: door-main at (-0.48, 0.004, 0.02). Connectors: e grid at (1, 0.004, 0) facing +X; w grid at (-1, 0.004, 0) facing -X. The door leaf swings on its hinge side. The lever, the lock and the frame are static. The ports are grid edges on the two metre module, not weapon sockets. Rigid node-transform clips open, close drive named nodes on their own pivots. No skinning and no skeleton. Blued gunmetal, bright machined steel, dark anodised alloy, black and dark earth polymer, rubber, walnut, brass, copper, leather, olive paint, optical glass, concrete and emissive red, green and warm white for reticles, lasers, tritium and lamps. Physically based flat colours with no texture maps. Original invented design: no real make, model, manufacturer or marking is represented.
