Modified: converted for the venue tree system (spec-gloss materials to metal-rough, leaf cards clipped to their image); the leaf atlases resampled from 2048 to 1024 cells and tone-matched to the game's earlier colours, the barks resampled (the birch bark turned and given a normal map derived from its colour); reduced LODs and octahedral impostors re-baked, textures re-encoded as WebP and KTX2.
  • “Coniferous Forest Assets Pack” by Dari, licensed under CC BY 4.0.
    The forest packs' fir, pine, noble fir, coniferous shrub and sapling, dead conifers and log, and boulders (now built from the identical models in the uncompressed Various Forest Assets Pack, above).

Parking lots: asphalt, concrete, stone, light poles and signs

The scanned mesh itself is not shipped..

    Used as the parking-lot template (the owner's choice): its stall, aisle and island proportions, curb and island layout, grass strips, paint (single stall lines, pale-yellow accessible symbols and hatched access aisles, aisle arrows), paving tones and lamp spacing were measured and are rebuilt procedurally (parking-kit.ts) and expanded to any lot size on the owner's asphalt / concrete materials and light poles; its reserved-parking sign face (generic, with the International Symbol of Access) is cropped from its texture, turned upright and re-encoded as a small WebP on a real-size sign. None of its meshes ships, nor its buildings, logos, window images, lamps or cars.

Press boxes: interiors, lights and glass

  • “Office building” by Nikitos & 3130, licensed under CC BY 4.0.
    Only the interior is used, for every stadium's press box: its office chairs, bookshelf, wardrobe, desk set and linear LED ceiling fixtures, its concrete floor tiles and its Roman-blind fabric, arranged into press-box booths and baked with the fixtures' light into a small texture of booth interiors (WebP) seen through the windows; one chair simplified to 180 / 100 triangles for the near view; the glass look follows its clear grey glass.
