A shopfront or lock up bay: a concrete wall with a 3.2 m by 3 m opening, guide channels each side and a slatted shutter with a yellow bottom rail hung from the box over the head. Dimensions 4.02 × 3.52 × 0.59 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Overcast realism: weathered concrete and faded brick, olive drab, gunmetal and machined steel, with hazard orange and safety yellow accents and emissive loot glows in the grey, green, blue, purple and gold rarity ladder. Rigid node-transform clips open, close turn named parts on their own pivots. No skinning, no skeleton, no collision or navigation data. A rigid node cannot roll a curtain into its drum, so the shutter leaf tilts up on the head hinge in one piece and the box, guides and wall stay fixed.
