Add Hair Rig

This tool adds a hair rig to the selected mesh.

  • Sectors: The number of sectors that the hair is divided into. Each sector corresponds to a bone chain.
  • Sector Offset: Offset between the first sector and the X axis.
  • Hair Length: The number of bones in each bone chain.
  • Keep Vertex Numbers: Keep vertex numbers. This is necessary for hair proxy meshes.
  • Vertex Groups: Create vertex groups based on Z coordinate
  • Control Method: Method for controlling the hair bones:
    • None: Each hair bone is controlled directly.
    • IK: An IK goal is placed at the end of each bone chain.
    • Bendy Bones: The hair is controlled by bendy bones.
    • Winder: Each bone chain is controlled by a winder.
  • Check Strips: Check that the hair mesh consists of strips in UV space.
  • Head: The name of the head bone. The root of each bone chain is parented to this bone.

The mesh strands are divided into sectors. In the middle of each sector there is a chain of bones that influence the vertices in the sector. The sector offset is the angle between the first bone chain and the X axis.

To the left we have the default twelve sectors, in the middle four sectors and zero sector offset, and to the right four sectors and a 45 degree offset.

If the Vertex Weights option is enabled, vertex weights are assigned based on the Z coordinate in real space. If this option is disabled, it is up to the user to skin the mesh, e.g. with automatic weighting or envelopes.

Control Method

There are four ways to control the hair deform bones: directly, with IK effectors, with bendy bones, and with winders.

None

If we choose none, the deform bones can be posed directly.

IK

The IK effectors are found in the Widgets collection, and the deform bones in the Hidden collection. We can now pose the hair with the IK goals.

Bendy Bones

Bendy bones offers most control. The deform bones are not selectable themselves, instead the hair is posed with the handles between them.

Winders

Winders offer a quick but inprecise method to adjust the hair.
