Interpolate Hair Curves
Interpolates existing guide curves on a surface mesh. The Duplicate Hair Curves is a similar option with simpler behavior that may offer better performance.
This node/modifier will not function without the Surface geometry/object and Surface UV Map inputs.
Input Geometry (only curves will be affected).
Surface geometry for generation. This input takes priority over the corresponding object input if both are provided.
Surface object for generation (Needs matching transforms).
- Mapa UV de Superficie
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.
In a typical hair generation setup, this node or modifier will be combined with the Deform Curves on Surface Node. If that operation comes after this one, it makes sense to turn this option on so the position used is the pre-deformed position consistent with the expectations for the deformation’s input.
- 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.
Surface density of generated hair curves.
- Density Mask
Factor applied on the density for curve distribution.
- Mask Texture
Discard points based on an mask texture after distribution. The image is sampled with the Surface UV Map input.
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.
Random seed for the operation.

- Guide Index
Index of the main guide curve per curve.
- Surface Normal
Normal direction of the surface mesh at the attachment point.
