There are a number of rigging add-ons available for Blender that allow you to construct a car rig. These are fine, but if you’ve ever wondered how to make one on your own, take a look at Christoph Werner’s new tutorial.
Basic rig setup to control a car in Blender Without using Addons
Christoph demonstrates how to rig a car model in Blender, allowing you to drive a vehicle down a custom-defined path. You’ll be able to specify the vehicle’s driving direction and speed, and it will respond. The wheels rotate by using the correct revolution, even if it means going backward.
The rig’s car driver also operates realistically, moving the steering wheel in the direction it is currently pointing.
