Building a Rigid Body Car in Blender: A Step-by-Step Tutorial

Are you ready to dive into the world of 3D modeling and animation in Blender? In this tutorial, we will walk you through the process of creating a rigid body car with a detailed axle system, steering controls, wheels, and suspension setup. By following these instructions, you'll learn how to build a dynamic and interactive car model right in Blender.

Getting Started

Let's kick things off by setting up the main axle, the foundation of our car model.

Start by adding a cube to serve as the main axle.
Navigate to the 'Physics' tab and add a 'Rigid Body' to the cube.
Adjust the settings to make the cube a 'Box' shape and set the weight between 1kg to 2kg for optimal performance.

Building the Axle and Steering System

Now, let's move on to creating the steering connector and arm.

Add another cube and position it at the center of the axle.
Modify the cube to resemble a steering connector by extruding and shaping it accordingly.
Set the origin to geometry and create a duplicate for the other side.

Adding Constraints for Steering and Suspension

To enable steering functionality and implement a suspension system:

Add a hinge-like generic constraint between the main axle and the steering connector.
Duplicate and mirror the constraints for both sides to ensure balanced steering.
Build the front and rear wheel wells using cylinders and Boolean modifiers to create realistic attachments.

Implementing Motors and Drivers

To control the car's movement and steering:

Set up a motor constraint to drive the wheels' rotation based on a throttle controller.
Configure steering controls by adding drivers linked to the steering object's movement.
Adjust surface response and damping settings for better traction and stability.

Testing and Optimization

Test your car model's performance on a simple track to evaluate its behavior and responsiveness. Make necessary adjustments to the suspension, friction, and weight settings to enhance the realism and functionality of the car.
