Verti-Curve is an add-on that uses Bézier curves to help align and smooth vertex paths during retopology. Users can select a continuous string of vertices to generate an approximating Bézier curve or circle. Once the curve is generated and manually adjusted to the desired flow, the tool can snap the original mesh vertices back to the nearest points on the curve. This workflow allows for smoother surface topology adjustments without the need to manually translate individual vertices.
