Hair Modeling

This will allow you to select strand tips, and model them with custom:

  • Transformation tools (IK, FK, Root - modes)
  • Extend (lengthen)
  • Knife (cut)
  • Linear Deformer (bend, rotate, scale, move)
  • duplicate/delete strands
  • adjust tilt and taper

Example of Hair Modeling tool in action. Selection Groups are used, to quickly select clumps of grouped strands

Location

Hair Modeling tool can be enabled from:

  • Left sidebar(T-key) > Hair Modeling icon in Object and Curves Sculpt mode

ht_hair_grooming

There are three strands transform modes available - under G,R,S keys:

  • Chain mode (IK) - move hair endings with rope like behavior
  • Normal mode which works same as blender proportional editing.
  • Root rotate or scale hair using root as pivot point

Showcasing Chain (IK) transform mode. Since HT 3.4 IK mode supports collisions of hair strands with scalp mesh
