Procedural Tank Tracks

In this Blender tutorial, I'll guide you through creating automatic tank tracks using geometry nodes. We'll start by making a customizable collection of cylinders, then use convex hull and decimate to form the track shape.

Next, we'll convert this shape to a curve and instantiate the track along it. Using vector math, we'll ensure the track aligns and moves correctly.

Finally, we'll add depth and gears, making sure everything functions smoothly. This advanced technique saves time and offers flexibility for different track shapes. Perfect for 3D animators looking to enhance their skills!
