Unfold — A Procedural Unfolding Spiral Setup.

Any custom curve—whether hand-drawn or generated—can be folded up and seamlessly unfolded into a dynamic spiral. Simply apply the Geometry Nodes setup, shape the thickness using the Curve Radius, and texture it as one continuous spline. The generated UV Map is automatically exposed as an Attribute for easy access in the Shader Editor.

How it works: This setup creates a seamless animation of a straight line rolling up into a coil, controlled entirely by a single slider. It mathematically generates both a straight base curve and a coiled spiral, aligning and seamlessly welding them together into one continuous thread. To make the shape look organic, the thickness and vertical height of the curve are driven by customizable graphs, allowing you to easily taper the ends or add wavy height variations. Finally, this unified thread is wrapped with a 3D profile to give it physical thickness and mathematically prepped for texturing.
