Hair Tool is addon for Blender 3.x and 2.93 that will help you generate hair-card based on 3d curves in non destructive way. (For Blender 2.92 and below you can use HT 2.27)
- Online documentation
- Discord server where you can get support and report bugs
- Hair Tutorial Part 1 and Part 2 by SinHouse
- YouTube channel with videos related to HTool
Business vs Individual license: if you are company with above 100k $ income you are Business. Otherwise you can buy individual license
Four main ways to generate hair-cards with Hair Tool:
- using guide mesh (grid surface)
- using particle hair interactive grooming
- by drawing hair strands (similar to Grease Pencil drawing)
- using short hair modeling method (new - based on geonodes works only on Blender 3.1 and above)
Some of the features:
- tools for curve based hair modeling (cutting, extending, deforming etc)
- 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
- textured hair-cards preview directly on curve and mesh ribbons
- hair library that contains various hairstyles,
- go back and forth between curve and mesh ribbons in non destructive way
- adjust ribbons profile (tapering radius, randomizing tilt, editing profile 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.
- texture baking from curves, particle hair of Geometry Nodes hair; supports: normal, ao, diffuse, tangent, ID, root maps etc
- build-in addon auto-updater
- and more

Update 1.8.5 (11.04.2018):

Update 1.9.2 (day 20.07.2018) - some bug fixes added in 11.08.2018:
- added select Next/Previous to curve editmode -> Select menu. I will select next point on curve.
- Interactive Child particles count can be set manually over 2000 (use with caution)
- generated curve ribbons will now have the rotation applied (this fixes bad curve ribbons aligning - 90deg offset)

Update 1.9.3 (26.08.2018):
- Fixed UV bug when going back and forward between curve and mesh mode.
- Randomize curve tilt - tilt can take positive or negative values.
- 'Include Parents' - option added in interactive hair combing - this will take into account Parent strands when using 'generate children option'.
- align curve tilt - make it work only on selected points. Previously it would align whole curve.
- Curve from grease pencil - now it has option to generate curve ribbons on the fly (https://bartoszstyperek.files.wordpress.com/2017/07/pg_to_curveribbon.gif?w=575&zoom=2).
Update 1.9.4 (03.11.2018):
- New clumping option added for - 'Curves from grid surface' operator.
- Speed boost to all tools that use curves resampling, including 'Interactive hair combing'. This affects lots of tools, but hopefully this didn't introduce any new bugs.
- fix jumping particle hairs when converting curves to particle hair
- Some of parameters can now be set above maximum value, by manually entering bigger values (eg. max curve ribbon width can now be set above 10)
