A battered utility quad 1.9 m long: a tube frame with a rusted engine cowl, a rubber seat, a barred rear cargo rack with a strapped bundle on it, front and rear mudguards, raked handlebars with rubber grips, a lit headlight and a small instrument pod. All four knobbly wheels turn on their own axles. Dimensions 1.10 × 1.25 × 1.93 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 wheel-roll turn named nodes on their own pivots. No skinning, no skeleton, no skin weighting, no collision or navigation data. The steering, the suspension and the brake levers are static: only the wheels turn.
