Heavy Truck KitTruck Controller : Model & Manual Gearbox PhysicsDrive a heavy truck the way it should feel. A complete, ready-to-use truck package: a realistic 3D truck model together with a full driving system that has a manual gearbox, clutch, brakes, audio system, and a working dashboard. Drop the prefab into your scene, press Play and drive.What’s includedRealistic truck model with separate wheels, steering wheel, dashboard needles, wipers and lights.Truck Controller script for WheelCollider-based physics, tuned for a heavy vehicle.Ready-to-use prefab with everything attached and assigned.Demo scene to test the truck immediately.Full documentation and a controls reference image.Key featuresRealistic driving physicsFront-wheel steering with smooth steering inputRear-wheel drive with 2 or 4 driven rear wheels (extra rear wheel pair is optional)Torque shared across all rear wheels, with an engine RPM limiterBrake system with a nose-dive effect (suspension changes while braking)Adjustable centre of mass for stabilityManual gearbox with clutch5 forward gears and reverse, with a customizable ratio and maximum speed for each gearClutch input, gear selection and neutralReverse / Drive / Neutral selector with UI buttons that change colourEngine start sequence (press E)Realistic audio systemEngine start, idle and driving loops that cross-fade smoothlyEngine pitch that follows the RPMBrake , horn with fade-out, reverse beeper and indicator tick Lights, dashboard and detailsLeft and right turn signals with blinking emissionBlinking parking lightWorking wipersSpeedometer and RPM needles with smoothing, plus speed and gear displayPause menu and controls menu hooks for your UIControlsKeyboard: W / A / D, Space for brake, Shift for clutch, Shift + 1-5 for gearsSteering wheel and pedal support through the Input Manager (throttle, steering, brake, clutch axes and wheel buttons)Camera pivot rotationEasy to customizeClean, commented code in the HunterCraft_Creations namespaceTechnical detailsUnity version: Unity 6 or newerInput: Unity Input Manager (old input system or Both)Requires: TextMeshPro, Unity UIRender pipeline: URPScripts: truck_, Switches, indicatorsWheel colliders: 4 minimum, 6 supportedFormat: FBX (specify based on your export)Polygon count: [e.g., ~200,000 tris — fill in actual count]Texture resolution: 4KUV mapped: Yes, non-overlappingRigged parts: Steering wheel, wheels (front/rear), doors, mirrors, suspension jointsI used AI tools for code reviews, documentation, and generating marketing images.
