设置毛发曲线轮廓

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.

输入

几何数据

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

替换半径

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.

半径

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

形状

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

最小系数

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

最大系数

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.

输出

几何数据

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