Hair Tool v3.6.6 for Blender Free Download

Hair Tool v3.6.6 for Blender Free Download

Hair Tool is add-on for Blender that will help you generate hair-card, shell hair or curve hair in non destructive way, using geometry nodes and python.

  • For Blender 3.6 (or 4.x) – use Hair Tool 3.x (only new hair curves are supported) – and: ‘’
  • For ‘old’ Blender 3.3 (up to 3.6) use ‘old’ Hair Tool. 2.46 (last version that supports ‘old’ curves) – and: with it.


  •  section in documentation – fastest way to get familiar with Hair Tool (10-15 min)
  •  for latest Hair Tool 3.x – it is is most up to date way of learning the addon
  •  place where you can get support and  report bugs
  • with videos related to HTool – use ‘Hair Tool 3.0’ playlist to see only new videos for latest HT 3.x
  • Hair Tutorialand by SinHouse – for ‘old’ HTool 2.46
  •  for old Hair Tool 2.46 – no longer maintained (last version that supported old curves and Particle Hair)


Studio vs Standard license: if you are company with above 180k $ income, please purchase Studio version. Both licenses (Studio and Standard) can be used commercially. Information about Hair Library license can be found

Refunds – you can get refund for Hair Tool, if you request it – withing 2 weeks after purchase.

Some of customers who purchased Hair Tool:

There are multiple ways to generate hair-cards with Hair Tool:

  •  – procedural hair generation based on geometry nodes – great for all kind of complicated hair styles (braids, curls, punk etc)
  • using(grid surface) – best for modeling long hair strands – now rewritten to use new hair curves, in HTool 3.x
  • using – great for short to medium hairstyles replaced by
  • similar to Grease Pencil drawing – now rewritten to use new hair curves, in HTool 3.x
  • using method – for short to medium length hair – animal fur, short human hairstyles
  • using modeling – great for very short hair (fur, carpet). Bit complicated to setup in game engine.

Some of the features:

  • tools for curve based (cutting, extending, deforming etc) – rewritten to support new curves
  • automated UV workflow (you can define uv regions, which can then be automatically assigned to hair strand)
  • easy hair rigging and animation with Jiggle physics
  • hair library that contains various hairstyles and sub-components,
  • various adjustable- Mesh Profile, Curls Profile, Circle, Flat, Braids etc.
  • convert: Curves to Particle Hair, Particle Hair to Curve ribbons, Curve ribbons to mesh ribbons and so on.
  • curve resampling and decimation (increases/decreases curve points count)
  • generating vertex color/weights gradients, transferring UVs and vertex weights from character to mesh haircards.
  • from new hair curves; supports: normal, ao, diffuse, tangent, ID, root, flow and more maps
  • build-in add-on auto-updater
  • and more

Hair tutorials for Blender 3.0 series (these are quite old – I’m in the middle of moving all the tools from od curves to new hair Curves):

New Videos (for Blender 3.3 and above) showing new based on Geometry nodes:

  •  using Shell Hair and Short Hair modeling techniques

Hair Tool can be used to export hair to
