Turbo Charged Custom Vehicle Generator earns its place in the superhive library for tying a fully customizable rig to Blender's own rigid body physics, with keyboard driving, recording and multi-vehicle support in one add-on.
Turbo Charged Custom Vehicle Generator is an animation tool for Blender that generates a completely customizable vehicle rig. You can set wheel and body dimensions, suspension, and performance settings including horsepower, torque, brakes and steering sensitivity, and switch a vehicle between front-wheel, rear-wheel or all-wheel drive.
The generated rig runs on Blender's rigid body physics, with motors that deliver power to the wheels and tire friction against the ground or surface driving the vehicle. Built-in body and wheel hitboxes handle collisions. The rig is recordable and has two modes: Drive mode, where you steer the active vehicle with keyboard shortcuts while an animation plays, and Watch Replay mode for viewing the recorded animation.
The tool is multi-vehicle capable, so you can generate as many vehicles as your computer can handle and switch between them by clicking a vehicle in the list to make it active. It suits scenes ranging from burnouts to monster trucks.
Turbo Charged Custom Vehicle Generator is best for blender artists creating physics-driven vehicle animation, from burnouts to monster truck scenes.
Turbo Charged Custom Vehicle Generator is completely free to download and use.
Turbo Charged Custom Vehicle Generator lists support for Blender versions 4.2, 4.0, 3.2, 3.1, 3.0, 2.93, 2.92 and 2.91, covering a long span from the 2.9 series through 4.2. If you run one of these versions, the add-on should install and generate rigs as described. For versions outside this list, check the developer's page, since compatibility with other Blender builds is not stated.
Turbo Charged Custom Vehicle Generator lets you drive the active vehicle from the keyboard while an animation is playing. Ctrl and Shift plus the up arrow applies gas, the left or right arrow steers, and the down arrow applies the brakes; holding the brakes puts the vehicle into reverse. This happens in Drive mode. The rig also has a Watch Replay mode, used only for watching the animation you recorded.
Turbo Charged Custom Vehicle Generator is multi-vehicle capable, letting you generate as many vehicles as your computer can handle. You switch between them by clicking a vehicle in the list, which makes it the active vehicle. Only the active vehicle is driven with the keyboard while an animation is playing, so you can build scenes with several vehicles and control each one in turn as you record.
Turbo Charged Custom Vehicle Generator is listed as free in this catalog, and its license is described as royalty free. Licensing terms can change over time, so check the developer's page for the current details before you rely on it for a project. The add-on comes from Kernberry's and includes documentation to help you get the rig set up and driving.
