This tutorial explains how to use the Curve modifier in Blender to deform objects along a predefined path. It demonstrates the technique using a practical example of animating a bread box lid. The guide covers several specific use cases, including deforming base meshes by modifying curve control points, arranging object clones along a path using the Array modifier, and animating objects organically as they translate along a curve. It also addresses troubleshooting steps for common modifier issues, such as unintended mesh tilting and path direction inversion.
