Set Hair Curve Profile

The Set Hair Curve Profile node defines the radius of hair curves along their length according to a customizable profile shape. It allows artists to control the thickness variation from root to tip, producing natural tapering or stylized width adjustments.

Inputs

Geometry

The input geometry containing the hair curves whose radius will be modified.

Replace Radius

When enabled, the node replaces the existing radius attribute with a new one. When disabled, the new radius is multiplied with the existing value instead.

Radius

The base radius value applied to all curves when Replace Radius is enabled. This sets the overall scale of the hair thickness.

Shape

Defines how the radius changes along the curve. For example, this can create a tapered profile, with thicker roots and thinner tips.

Factor Min

The multiplier applied to the radius at the start (root) of each curve. Typically used to control how thick the curve starts.

Factor Max

The multiplier applied to the radius at the end (tip) of each curve. Typically used to control how thin the curve becomes toward the tip.

Outputs

Geometry

The resulting geometry with updated radius attributes along each hair curve.
