In this blog, we will explore the fascinating world of mechanical rigging in Blender and create a realistic animation of a single-piston crank engine mechanism. Blender is a powerful open-source 3D modeling and animation software, and rigging enables us to add movement and interactivity to our 3D models. We will walk through the step-by-step process of creating a functional crank engine animation and understand the key concepts involved in rigging.
