I've provided a set of additional wall and tyre-wall sections, for creating custom tracks on the large tarmac or grass areas.
The model includes track, pit, road, and grass sections, plus walls, grandstands, timing towers, foot / road bridges, lighting, pit buildings, marshall towers, working startlights and a skydome.
All 18 textures and are included and are game-ready (256x256 or 512x512 pixels). There are no opacity maps.
There are 2 max versions, 1 including vertex lighting assigned using radiosity and 1 without lighting, all other versions have default lighting.
