Straighten Hair Curves

The Straighten Hair Curves node aligns the points of each hair curve along a straight line between its root and tip. This can be used to relax curly or noisy hair, create stylized grooms, or prepare curves for further deformation or simulation.

Inputs

Geometry

The input geometry containing the hair curves to straighten.

Amount

Controls how much each curve is straightened. A value of 0.0 leaves the hair unchanged, while 1.0 fully aligns points along a straight line. Negative values exaggerate curve irregularities, causing crumpling or distortion.

Shape

Defines how the straightening influence changes along the length of each curve. A value of 0.0 applies a constant effect, while 0.5 produces a linear falloff from root to tip.

Preserve Length

When enabled, keeps the original length of each curve during deformation. When disabled, curves may shorten or stretch slightly as they are straightened.

Outputs

Geometry

The resulting geometry with straightened hair curves.
