About
A dog-leg stair core: two 1.5 m flights hanging off the near edge of a full-width half landing, so the climb turns through 180 degrees and returns to the same wall one storey up. Dimensions 4.05 x 4.02 x 3.42 m (X x Y x Z). Origin at the centre of the stair core on the lower deck datum. The up flight is on the -X side and the return flight on the +X side; the landing is at the +Z end. Metres, +Y up, +Z front, ground contact at y=0. Both ports face -Z at the open end of the core: the base on the lower deck, the top on the upper deck 3.00 m above. Connectors: base (deck-edge), top (deck-edge). Neutral greybox palette for prototyping before art exists. Static geometry; no skinned rig, collision or navigation data.
