Eight metre gatehouse for the city wall: two limestone blocks either side of an arched passage, a lifting iron portcullis in its runners, a pair of banded oak gate leaves and a crenellated fighting top over a brass city crest. Dimensions 9.00 x 7.94 x 4.00 m (X x Y x Z). Pivot on the 4 m grid origin at ground level, the passage running along Z; metre units, +Y up, +Z front. Named pivots: portcullis at (0, 0.74, 1.02); gate-l at (-1.58, 0.44, -0.9); gate-r at (1.58, 0.44, -0.9). Connectors: e wall at (4, 0, 0) facing +X; w wall at (-4, 0, 0) facing -X. The portcullis and the gate leaves are separate systems, so each carries its own clip pair. The winch gear above the passage is modelled solid and does not turn. Rigid node-transform clips portcullis-open, portcullis-close, gate-open, gate-close drive named nodes on their own pivots. No skinning and no skeleton. Hand painted palette of deep warm limestone, dark terracotta roofs, ochre render, near black walnut framing, russet oak, brass and city crimson and blue, with emissive flame and arcane crystal for the lit pieces. Procedural 1024 px base colour maps, no normal or metal roughness maps. Free 3D model for Unity, Godot, Unreal, three.js and Blender. No collision or navigation data.
