Soviet 6x4 farm dump truck with a towed trailer: spline autopilot, manual driving, lights, turn signals, engine sound and exhaust smoke. URP.A classic Soviet-era 6x4 agricultural dump truck with wooden-side body, tarp and a matching two-axle towed trailer — ready to drive the moment you drop it into a scene.Two ways to drive:- Spline autopilot: draw a route along your own roads with the DrivePath tool (move points in the Scene view, insert / remove, snap to ground; the path is visible through any object), assign it to the truck and it drives by itself — slows down in curves, uses turn signals, loops or stops at the end of a one-way route.- Manual driving: take the wheel and drive with the keyboard. Switch between autopilot and manual at any time (T in the demo, or one call from your code).FEATURES- Drivable truck on WheelColliders: 6x4 (rear 4 wheels driven, front 2 steer), handbrake, reverse- Towed trailer on a physics hitch, front axle steers by itself and follows the truck in turns; trailer brakes and lights follow the truck- Headlights (spot lights), brake and tail lights, left / right turn signals, hazard lights — lamp glass glows- Engine and turbo sound driven by engine RPM, exhaust smoke that reacts to throttle- Your own AI or game logic can drive it too: set throttle / steer / brake from any script- 3 LODs on truck and trailer, simple box colliders- Demo scene: one truck drives the road loop on autopilot while you drive the second one; chase camera (C switches between trucks), on-screen help- Plain C# source, works with the old Input Manager and the new Input System, no dependencies- Unity 2022.3 LTS or newer, Universal Render Pipeline- Truck: 22,588 tris (LOD0) / 11,292 (LOD1) / 4,914 (LOD2, no cab interior)- Trailer: 14,300 tris (LOD0) / 7,146 (LOD1) / 3,571 (LOD2)- Real-world scale: truck ~3.0 x 8.7 x 3.2 m, trailer ~2.7 x 8.6 x 3.2 m- Textures: PBR 2048 x 2048, 2 sets — BaseColor, Normal, MaskMap (Metallic / AO / Smoothness)- Materials: URP Lit (double-sided) — body, chassis, interior, glass, 4 lamp materials- Prefabs: truck + trailer, truck, trailer, drive path- Scripts: TruckController, SplineAutopilot, DrivePath (+ Scene view editor), TrailerHitch, VehicleLights, EngineAudio, ExhaustSmoke- Audio: engine loop, turbo loop (WAV)- Preview images: environment of the cover is not includedAn AI assistant helped with general project work — management, scripting, Unity setup, packaging and the description; the 3D model and textures were made by the author.
