Hair Tool for Blender
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: 'HairLibrary_3.x_date.zip'
- For 'old' Blender 3.3 (up to 3.6) use 'old' Hair Tool. 2.46 (last version that supports 'old' curves) - and: HairLib_18_12_2022.zip with it.

There are multiple ways to generate hair-cards with Hair Tool:
- Hair System - procedural hair generation based on geometry nodes - great for all kind of complicated hair styles (braids, curls, punk etc)
- using grid Guide Mesh - to guide hair. Best for modeling: long hair, buns, fringes, eyelashes etc. Very good for low-poly characters.
- using Track To Mesh - great for short to medium hairstyles
- grooming tools - that can be used together with Blender Curve Sculpt mode and procedural effects - Deformers
- drawing and extending hair strands similar to Grease Pencil drawing - now rewritten to use new hair curves,
- short hair modeling - for short to medium length hair - animal fur, short human hairstyles. Haircards will be spawn from each mesh edge.
- using shell hair modeling - great for very short hair: fur, carpets. Requires special material (there is UEngine material in HTool docs)
Some of the features:
- tools for curve based hair modeling (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 ribbons profiles - 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.
- texture baking from new hair curves; supports: normal, ao, diffuse, tangent, ID, root, flow and more maps
- build-in add-on auto-updater
- and more
