About
Everything needed to build a club karting circuit and run it. The fleet is a hire kart with a floor tray, bucket seat, raked steering column, live rear axle with sprocket and brake disc, a side mounted engine, nerf bars and four exposed wheels, in three house liveries, plus a race chassis with number panels, a junior chassis at 0.82 scale, a trolley, a kart sitting on its trolley and a spares rack of seats and steering wheels. The circuit tiles on real connector ports: 8 m tarmac straights, a ninety degree corner, a start grid tile, pit lane concrete, plain paddock apron and gravel run off all share the same ground module, so a plot lays as one continuous surface. Lining it are 4 m red and white apex kerbs, tyre wall sections and a corner, advertising boards, spectator fencing and grandstand bays, with a start gantry, timing loops, apex and bollard cones, sign sets and a marshal post with flags. The pit side is a terrace of 5 m garage bays with lifting roller shutters, race control over the lane, a scoring screen, a lap counter, a briefing board, kart storage racks, a fuel and charging point, tool trolleys, tyre stacks and an air line reel, and the entrance has the reception counter, podium, trophies, helmet and suit racks, a vending machine, benches and bins. Clips are rigid node transforms only: kart and trolley wheels roll, garage shutters lift, the air drum spins, the start lights and the scoring screen tilt, the bin lid opens and the vending door swings. Steering columns, drive chains, air and charge hoses, tyre wall ropes and the flags are modelled solid and stated as static, because each needs a joint or a deformation per element that a rigid node cannot give. Liveries, numbers, boards and signage are invented and copy no real series, circuit or manufacturer. Original AI-generated CC0 geometry, prepared for human review. No physics, gameplay, colliders, navigation or embedded lights.

AnimatedRental Kart (Go Kart Track and Pit Lane)
Club hire kart with a blue bodywork set: flat floor tray on two chassis rails, a bucket seat, a raked steering column, a live rear axle with sprocket and brake disc, a side mounted engine, nerf bars and four exposed wheels on their own pivots.
AnimatedRental Kart Red Livery (Go Kart Track and Pit Lane)
The club hire kart repainted into the second house colour: red pods, nose and bumper hoops on the same chassis, seat, axle and wheels. Geometry is identical to the blue kart, so a hire fleet mixes the two without a second model.
AnimatedRental Kart Yellow Livery (Go Kart Track and Pit Lane)
The club hire kart in the third house colour: yellow pods, nose and bumper hoops over the same chassis, seat, axle and wheels. Geometry is identical to the blue kart and the wheel nodes carry the same names, so the roll clip is unchanged.
AnimatedRacing Kart with Number Panel (Go Kart Track and Pit Lane)
Race chassis in red with a yellow number panel on the nose and a number plate on each pod, yellow wheel hubs, a bucket seat, a live rear axle with sprocket and brake disc and a side mounted engine. Four wheels on their own pivots.
AnimatedJunior Kart (Go Kart Track and Pit Lane)
Cadet chassis at 0.82 of the adult kart: shorter wheelbase, narrower track and a smaller seat, in yellow with a blue nose flash. Same floor tray, steering column, live rear axle and four pivoted wheels, sized for a junior class grid.
AnimatedKart Trolley (Go Kart Track and Pit Lane)
Empty steel kart trolley: a two rail deck 0.5 m off the floor on four legs, an end brace each end, a lower shelf rail and a red topped push handle, running on four castors that each turn on their own pivot.
AnimatedKart on Trolley Stand (Go Kart Track and Pit Lane)
A hire kart sitting on its trolley, wheels clear of the floor, the way a paddock stores and moves one. Trolley castors and kart wheels are all pivoted nodes, so the roll clip turns every wheel on the assembly at once.
Spare Seat and Steering Wheel Rack (Go Kart Track and Pit Lane)
Paddock spares rack 1.6 m wide: two bucket seats hooked over the top rail in red and blue and two steering wheels on pegs below, on a welded steel A frame with a low kick rail. Static geometry, for dressing a garage or a workshop wall.
Track Surface Tile Straight (Go Kart Track and Pit Lane)
Straight 8 m tarmac circuit tile on a 0.12 m slab, with a white edge line down each side of the 8 m racing corridor. Four ground ports, one per edge, so straights, corners and pit tiles lay as one continuous surface.
Track Surface Tile Curve (Go Kart Track and Pit Lane)
Ninety degree corner tile on the same 8 m module: the corridor enters the west edge and leaves the south edge, the outer edge is lined in white and the apex arc is dotted round the inside. Four ground ports, one per edge.
Grid Box Marking Tile (Go Kart Track and Pit Lane)
Start grid tile: the same 8 m tarmac module with a white start line across it and six staggered grid boxes painted in two rows, the spacing a kart grid uses. Four ground ports, so it drops into a straight in place of a plain tile.
Run Off Gravel Tile (Go Kart Track and Pit Lane)
Gravel trap tile on the 8 m ground module: a raked pea gravel bed with a scatter of larger stones, for the run off behind a tyre wall. Four ground ports, so it lays flush against tarmac, pit concrete and its own neighbours.
Kerb Section Red and White (Go Kart Track and Pit Lane)
Four metre apex kerb, 0.5 m wide, rising from 50 mm at the track edge to 85 mm at its back lip, in white concrete with four red bands laid proud of the slope. Start and end kerb ports, so a run follows a corner in 4 m steps.
Tyre Wall Barrier Section (Go Kart Track and Pit Lane)
Four metre tyre wall: three courses of six bolted tyres 0.66 m high with red and blue marker tyres banded through them, a steel end post each end and a yellow strap board along the track face. Start and end barrier ports.
Tyre Wall Barrier Corner (Go Kart Track and Pit Lane)
The tyre wall turned through ninety degrees: two 2 m arms of three courses meeting at a knuckle tyre, with the yellow strap board carried round both faces and a steel post at each open end. Barrier ports on both arms.
Barrier Board with Advertising (Go Kart Track and Pit Lane)
Four metre advertising hoarding for the outside of a barrier: a blue board 0.9 m high on two steel posts with back stays, blocked out in yellow and red, and a dark capping rail. Panels are invented blocks of colour and carry no wording or logo.
AnimatedStart Finish Gantry (Go Kart Track and Pit Lane)
Start and finish gantry spanning a 10 m corridor on two 4.5 m steel legs with concrete pad footings: a braced box beam, a red and yellow banner panel and a five lamp start light panel hung below it that tilts on its own pivot.
Timing Loop Strip (Go Kart Track and Pit Lane)
Transponder timing loop laid across an 8 m corridor: a bonded charcoal strip with a yellow marker tape each side and a small roadside reader box on the verge. Sits on the tarmac, so it drops on a straight wherever a split is taken.
Apex Marker Cone (Go Kart Track and Pit Lane)
Small red apex cone 0.37 m tall on a square weighted base with a white reflective band, the marker a clerk drops on an apex or a braking point. Static geometry; the cone is one solid, so it never tips.
Bollard Cone (Go Kart Track and Pit Lane)
Tall 0.84 m bollard cone on a heavy square base with two white bands, for a pit entry, a lane split or a closed gate. Same family as the apex cone, scaled up and double banded so it reads from a distance.
Track Sign Set (Go Kart Track and Pit Lane)
Pair of circuit signs on concrete footings: a 2.1 m post with a yellow chevron board and a red warning plate, and a 1.6 m post with a blue direction arrow. Symbols are plain shapes and name no series, circuit or maker.
Flag Post and Marshal Post (Go Kart Track and Pit Lane)
Marshal post: a raised 2.4 m concrete stand with a yellow double rail on three sides, an extinguisher on the deck, and a 3.1 m flag post beside it carrying a yellow and a red flag panel. The flags are modelled as rigid panels and do not move.
Pit Lane Tile (Go Kart Track and Pit Lane)
Pit lane surface on the 8 m ground module: a concrete slab with a red boundary line on the track side, a yellow fast lane line down it and one working bay boxed out in white against the garage side. Four ground ports.
Paddock Apron Tile (Go Kart Track and Pit Lane)
Plain poured concrete apron on the same 8 m ground module, its slab scored into four bays by expansion joints. The unmarked companion to the pit lane tile, for paddock, garage forecourt and parking ground. Four ground ports.
AnimatedPit Garage Bay Module (Go Kart Track and Pit Lane)
One 5 m pit garage bay, 6 m deep and 3.1 m to the roof: half thickness party walls, a back wall with a steel bench, a strip light, a blue header with a bay number plate and a ribbed roller shutter that lifts in its guides.
Kart Storage Rack (Go Kart Track and Pit Lane)
Two tier steel storage rack 1.5 m wide holding two hire chassis, one red and one blue, on runner shelves with edge lips and a red top rail. The stored chassis are simplified to tray, seat, nose and wheels and do not move.
Fuel and Charging Station (Go Kart Track and Pit Lane)
Bunded refuelling and charging point on a kerbed concrete plinth: a red fuel cabinet with a nozzle on its hose, a blue charge post with two leads and a canopy plate, and a fire point. Hoses and leads are modelled solid and do not move.
Tool Trolley (Go Kart Track and Pit Lane)
Red four drawer tool trolley on four castors with a steel worktop, a push handle and a few tools left on the lid. Drawers and castors are modelled solid on this one and do not open or turn; the pit garage bay is what carries a moving part.
Tyre Stack (Go Kart Track and Pit Lane)
Stack of five kart tyres 1.1 m high with a red and a blue marker tyre banded through it, a yellow cap disc on top and a strap rod down the side. Fits the tyre wall family, so a paddock stack and a barrier read as the same rubber.
AnimatedAir Line Reel (Go Kart Track and Pit Lane)
Free standing air line reel on a 2.1 m post: a red drum on a bracket that spins on its own pivot, a blue hose run down to the gun and a compressor box at the foot. The hose itself is one rigid solid, so it does not pay out with the drum.
Race Control Tower (Go Kart Track and Pit Lane)
Two storey race control: a 3.6 m concrete base with a door and a louvre band, an external stair with a yellow rail, and a glazed control box above it overhanging the pit lane, with a roof rail, a mast and a results board on its front.
AnimatedScoring Screen on a Stand (Go Kart Track and Pit Lane)
Live timing screen 3.7 m tall on a concrete footing and two braced posts: a charcoal case with a blue panel and five yellow result rows, hung on a head rail so the whole screen tilts to the crowd on its own pivot.
Driver Briefing Board (Go Kart Track and Pit Lane)
Free standing briefing board on an A frame: a white 1.9 m panel under a red header, with a track map blocked out on the left, four ruled lines on the right and a pen tray along the bottom. Markings are plain shapes and carry no wording.
Grandstand Section (Go Kart Track and Pit Lane)
Six metre grandstand bay: four raked rows of red and blue seat pans on cast concrete steps, yellow side and back rails and steel end frames. Start and end stand ports, so bays run along a straight or round the outside of a corner.
Spectator Fence Section (Go Kart Track and Pit Lane)
Four metre spectator mesh fence 1.85 m high: a welded panel between two steel posts with yellow top and kick rails. Start and end fence ports, so a run closes a viewing line without a gap at the joins.
Helmet and Race Suit Rack (Go Kart Track and Pit Lane)
Hire kit rack 1.9 m wide: two race suits on hangers under a helmet shelf holding two helmets, with a boot shelf below and a welded steel frame. Suits and helmets are modelled solid and none of it moves.
Race Suit on a Hanger (Go Kart Track and Pit Lane)
A single red race suit on a hanger on a weighted floor stand 1.9 m tall, with a black chest band, a yellow flash and a wire hook over the rail. One rigid piece: the suit is solid geometry and does not drape or move.
Racing Helmet (Go Kart Track and Pit Lane)
Single full face karting helmet 0.33 m across, red shell with a dark visor band, a chin bar and a small rear spoiler, resting on its own padded ring so it sits level on a shelf, a bench or a tyre stack.
Kart Club Reception Counter (Go Kart Track and Pit Lane)
Reception desk for a karting club: a 3.4 m blue counter with a return, a pale worktop, a yellow rail along the public face, a till and card reader, and a results board on posts behind it. Static geometry, nothing opens.
AnimatedVending Machine (Go Kart Track and Pit Lane)
Red drinks and snack vending machine 1.92 m tall with a yellow header, a glazed door showing three shelves of stock, a dispensing flap and a handle. The door swings on its own hinge; the stock is modelled into the door and travels with it.
Visitor Bench (Go Kart Track and Pit Lane)
Slatted blue bench 1.7 m long on two steel end frames, with three seat slats and a raked three slat back. Ground origin at the centre of the footprint, so it sits straight on a paddock apron or a viewing area.
AnimatedLitter Bin (Go Kart Track and Pit Lane)
Public litter bin 1.05 m tall: a tapered charcoal body with a yellow band, a foot plate and a blue domed lid hinged along its back edge on its own pivot.
Podium with Three Steps (Go Kart Track and Pit Lane)
Three step prize podium on a low deck: a 1.05 m centre block in yellow between a 0.76 m and a 0.52 m step, each with a dark tread cap and a blue number plate on its face. Plates are blank blocks and carry no wording.
Trophy Set (Go Kart Track and Pit Lane)
Set of three trophies on a presentation tray: a gold, a silver and a bronze cup on stepped plinths, the tallest 0.65 m, each with two handles. Blank castings with no engraving, ready to stand on a podium or a reception counter.
Lap Counter Board (Go Kart Track and Pit Lane)
Manual lap counter on a 2.3 m post with a concrete footing: a dark board carrying three white number cards under a yellow header, with a red ledge below for the spare cards. Cards are blank plates; nothing flips.
Club Circuit Corner and Pit Lane (Go Kart Track and Pit Lane)
A club karting circuit on a 56 x 48 m plot laid as one continuous surface: a tarmac straight with the start gantry over it, six grid boxes marked out underneath and karts lined up on them, turning right through a corner tile with a red and white kerb round the apex. The...
