Curve Populate

Overview

Curve Scattering Tool for Geometry

This tool allows you to scatter curves onto geometry, ideal for creating short curly hairstyles like afros. Begin by creating a few initial curly curves, then randomly distribute them across a base mesh.

Before you use this tool, please have the base mesh UV laid out in 1001 UV space!

Input Mesh

Prior to scattering, please select a geometry and click 'set' into the input box. Scatter Method: UV:

• A geometry need to be 'set'. Please use the 'Set' button to define a mesh.

• ​Use the UV of the defined geometry for scattering. The larger the UV shell is, the denser the curves. Please ensure there's no overlapping UVs.

• UV must be in 1001 space.

Vertices

• ​Please select vertices for curves to populate onto.

• A geometry need to be 'set'. Please use the 'Set' button to define a mesh. This is for orientation purpose.

Source Curves

Custom:

• ​Randomly sample curves added to the list and scatter onto defined geometry.

Straight:

• ​Scatter onto defined geometry with straight curves only.

Scatter Parameters

UV Scatter Mode:

• Density:

  • Each sampled curve will be placed randomly on the mesh.

• Spacing:

  • ​Each sampled curve will be placed based on the geometry's UV placement.

Scale Multiplier:

• Multiplier for curve sale.

Density: ('Density' UV Scatter Mode Only)

• Number of curves to be randomly placed. Note, the number of curves should be treated as approximate.

​Spacing: ('Spacing' UV Scatter Mode Only)

• Controls the 'density' of scattered curves. Lower values will decrease the spacing between curves, yielding more curves (slower processing time).

• Start with a high number, and lower this value in increments to avoid long processing time.

• To speed up process, consider scattering multiple time with higher 'Spacing' values to create iterations or 'layers' of curves instead of one full dense pass. Use the 'Random-Spacing' slider to create random placements.

Random - Scale:

• Randomize the scale of scattered curves. This is a multiplier to the 'Scale' slider. A value of 0.500 in Random-Scale will multiply curves randomly between range of 50% ~ 100% of their set scale value.

Random - Spacing: ('Spacing' UV Scatter Mode Only)

• Randomize the spacing between curves, for uniform rows and columns, keep this at 0. The higher the value, the more randomly spaced out the curves scatter will be.

Random - Rotation:

• Randomizes the rotation of each curves.

Scatter:

• Populate curves onto defined mesh/vertices.
