Sculpt Mode

Hair Modeling Tools

Following the launch of Hair Tool 3.4, Hair Modeling tools can now be utilized in 'Curve Sculpt' mode (previously it was available only in Object mode)

Editing may bit slow, since on every update, whole hair system is being recalculated.

This combined with Selection Groups, allows for very powerful and flexible workflow.

Strands Selection

Selection Groups

Selection Groups allow you to assign a unique identifier to individual strands, making it easy to re-select them later.

Select clump of strands with Blenders build-in 'Select Brush' then press Assign New ID. Later you can re-select these strands by using Select Group button and then picking hair strands using (Shift+) LMB in 3D View

Note: If you want assign hair clump to existing group use Assign Id: [x] - where [x] is Active Group number

Selection Group From Island - it will assign group ID to each strand, where ID will depend on the mesh island strands originated from.

Selection By Island

If hair source surface (scalp) is divided into several sections, you can select hair strands that come from a specific section (mesh island).

Scalp mesh is divided in few section (islands). Use 'Select Island' button and then left click in 3D View, to select hair strands that are originating from picked island

Note: instead of splitting the edges physically, you can use the Edges split modifier. First mark edge as sharp

Helpers (un)Hide

You can also use Hotkeys:

  • H key - will hide hair strands
  • Alt+H - will reveal hidden strands
