Gridstart builds ready-to-drive go-karts and small off-road vehicles inside Blender. Pick one of 47 designs in ten families, from a CIK sprint kart with a tuned pipe to a VW Manx dune buggy, a V8 sand rail with paddle tyres, a four-seat UTV, a farm quad with racks or a wooden soapbox racer, then change anything: every part is a picture, a slider or a switch, and the vehicle rebuilds in a moment.

Each vehicle is built like the real thing. Bent tube chassis and roll cages with welded joints, kingpins and spindles, disc brakes and calipers, coil-over shocks, chains and sprockets, seat shells and racing buckets with harnesses, pedals, a steering column and a real steering wheel or handlebar. Engines include air- and water-cooled two-strokes, a KZ shifter with radiator, a rental four-stroke, an electric motor with batteries, a CVT single, an air-cooled VW flat four and a small-block V8 with zoomie headers.

It is rigged and ready to animate. Steering turns the front wheels with real Ackermann geometry and turns the steering wheel or handlebar with them. Drive rolls all four wheels, and one button makes the wheels roll whenever you move or keyframe the vehicle. Empties mark the driver's seat, hands and feet so a character drops right in.

Liveries come with racing stripes, two-tone, side bands, fades and camo, race numbers on yellow, white, black or livery plates, vinyl sponsor stickers that wrap over the kart bodywork, and six conditions from showroom to race day, trail dust, muddy, worn and barn find. All materials are photoreal PBR with real Poly Haven textures: satin moulded kart plastics, fibreglass seat shells, tube-and-fin radiator cores, see-through window nets and TIG weld beads on every frame joint. They work in Cycles, EEVEE and game engines.

47 karts and buggies
Sprint and shifter karts, rental karts, dune buggies, sand rails, UTVs, quads and soapbox carts. Pick one and change anything.

One click, a new ride
Surprise Me builds a new vehicle with its own proportions, livery, number and wear every time.

Steers and rolls
Ackermann steering turns the wheels and the steering wheel together, and the wheels roll as the vehicle moves.

Showroom to barn find
Six conditions with real dirt, mud, dust, chipped paint and rust, all live in the material.
