Warp Roots Modifier 

Warp Roots is a specialized modifier that provides precise control over hair, fur, and feather root distribution. This modifier allows you to interactively bunch together or spread apart root positions using an intuitive painting interface, which is particularly useful when modeling feathers or sparse fur patterns.

 

Parameters 

A set of artist-friendly parameters allow quick control over hair distribution with minimal setup. These parameters can be manipulated using texture maps, Strand Groups, Guide Channels and mesh vertex colors. See the corresponding page for more information.

• Density
  The primary control for warping root positions. Paint lighter values to bunch roots together and darker values to spread them apart.
• Strength
  Controls the intensity of the warping effect. Increase for more pronounced distribution changes.
• Iterations
  Number of Jacobi iterations
• Resolution
  Grid resolution

 

Workflow 

1. Add the Warp Roots modifier to the top of your Ornatrix stack
2. Click the "Create" button next to the Density Channel option
3. Select "Paint Strands" option
4. Move the created Edit Guides modifier to directly below the Warp Roots modifier
5. Paint strands with lighter colors where you want denser hair distribution
6. Adjust the "Strength" parameter for more pronounced effects
7. Continue painting as needed - lighter values bunch roots together, darker values spread them apart
