pipe shoring frame, inspection gantry, fenced excavation site, compact tracked
excavator, maintenance truck, Metropolitan Police patrol sedan, Tokyo Fire
Department pump appliance.

Reference photographs are not included in the game. Shapes, proportions and
road placement are creative game adaptations, not an exact engineering model,
road-safety guide, or claim of official affiliation.

Models use portable PBR materials and original geometry. Japanese lettering is
locally typeset into embedded PNG atlases. Meshes are batched by material role;
three wheeled vehicles preserve four independent rolling-wheel nodes each.
Game coordinates are metres, up +Y, front +Z. Models are grounded and fitted
uniformly to collision footprints without independent axis stretching.
Construction source, original scene GLB/Blender file, Eevee previews, processed
asset reports and tests are retained in work/tokyo-roadworks/ and work/tokyo-roadworks-premium/.

## Sculpted forms and portable surface detail

Revision 6 replaces primitive vehicle bodies with continuous lofted shells, shaped wheel openings, conforming glazing, hollow multi-spoke wheels, layered optics and functional pump controls. Construction details include cast cover traction, shoring clamps, pleated safety fabric, hydraulic hoses and a formed bucket. Eight-ray contact occlusion and albedo are baked to vertex colours; no extra runtime postprocessing is needed. Original rolling wheel pivots and collision sizes remain. High-detail editable source is retained separately; game geometry is simplified and batched without an external geometry decoder.
