Dimensions 1.47 x 2.07 x 1.47 m (X x Y x Z). Metre units, +Y up, +Z front; the model rests on y=0 with its origin on the footprint. Connector ports: down (stair) at (0.00, 0.00, 0.00); up (stair) at (0.00, 1.20, 0.00). Pivot on the newel axis at the floor. Ports down at the base and up at 1.2 m, so segments stack inside the base and mid stages of this lighthouse. Static geometry: no rig, animation, collision or navigation data. Free 3D model for survival game and open world prototypes, in the muted green, grey, rust and driftwood island palette with orange fire and yellow hazard accents.
