About
The light engine that a crew hauls by hand. A braced timber carriage on four solid wheels carries a single arm with a leather bowl at the tip and eight pull ropes at the butt, working against a padded crossbeam stop. The throw clip rocks the arm through its full travel and the wheels roll. The pull ropes are a linkage and are modelled slack and still. Dimensions 2.77 × 1.99 × 4.51 m (X × Y × Z). Ground-contact origin under the footprint. Metre units, +Y up, +Z forward. Kingdom limestone, ashlar, timber, oak, iron, cloth, slate and straw, the palette shared with the castle construction and faction building packs. Rigid node-transform clips throw, wheel-roll turn named parts on their own pivots. No skinning, no skeleton, no collision or navigation data.
