A rifle built in the camp out of what came to hand: a steel pipe barrel clamped into a folded plate receiver on a rough pine plank stock, bound with wire and tape at three points, with a hand bent bolt handle, a taped box magazine in a plate well and iron sights filed from strip. Dimensions 0.12 × 0.30 × 1.24 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Damp conifer forest realism: wet concrete and corroded corrugated steel, weathered pine, dark bark and soil, deep needle green, olive canvas, gunmetal and machined steel, with five emissive colours (amber fire, white floodlight, green status, blue screen, red warning) that also form the loot rarity ladder. Rigid node-transform clips magazine-open, magazine-close, bolt-open, bolt-close turn named nodes on their own pivots. No skinning, no skeleton, no skin weighting, no collision or navigation data. The wire bindings, the tape and the trigger are static geometry; only the magazine and the bolt move.
