Interpolate Hair Curves

Note

This node/modifier will not function without the Surface geometry/object and Surface UV Map inputs.

几何数据（Geometry）

Input Geometry (only curves will be affected).

曲面

Surface geometry for generation. This input takes priority over the corresponding object input if both are provided.

曲面

Surface object for generation (Needs matching transforms).

表面UV贴图

Surface UV map stored on the mesh used for finding curve attachment locations.

Surface Rest Position

Set the surface mesh into its rest position before attachment.

Tip

Follow Surface Normal

Align the interpolated curves to the surface normal.

Part by Mesh Islands

Use mesh islands of the surface geometry for parting.

Interpolation Guides

Amount of guides to be used for interpolation per curve.

Distance to Guides

Distance around each guide to spawn interpolated curves.

Poisson Disk Distribution

Use poisson disk distribution method to keep a minimum distance.

Density（密度）

Surface density of generated hair curves.

Density Mask

Mask Texture

Discard points based on an mask texture after distribution. The image is sampled with the Surface UV Map input.

Tip

The accuracy of sampling the image doesn’t depend on the density of the surface mesh’s vertices because it is sampled after the curve root points are generated, the accuracy . However, using the Density Mask input instead can give better performance. Using them in combination can give the benefits of both methods.

Viewport Amount

Factor applied on the density for the viewport.

种子

Random seed for the operation.

Guide Index

Index of the main guide curve per curve.
