Hair Tool is addon for Blender 2.93 that will help you generate hair-card based on 3d curves in non destructive way. (For blender below 2.93 you can still use HT 2.27)

- Discord server where you can get support and report bugs

Business vs Individual license: if you are company with above 100k $ income you are Business. Otherwise you can buy individual license
Three 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)
Some of the features:
- automated UV workflow (random uv region assignment per hair strand)
- texture preview directly on curve ribbons
- curve modeling tools (extend, shorten, cut, move hair with IK physics)
- hair library
- go back and forth between curve and mesh ribbons
- 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 (increase/decrease curve/ribbon points count)
- generating vertex color/weights gradients, transferring UVs and vertex weights from character to mesh haircards.
- texture baking (from curves or particle hair; supports: normal, ao, diffuse, tangent maps, ID maps, root map etc)
- build-in addon auto-updater
- and more

- added ability to attach curves as particle hair system 'Particle Hair from Curves' (this can be used to import zbrush fibermesh curves and use them as blender Particle Hair system)
- added 'Generate ribbon weights' - make vertex group with gradient from ribbon root to tip
- added 'Generate ribbon vertex color' - make vertex color with gradient from ribbon root (black) to tip (white)
- added ability to draw multiple uv boxes when using 'UV hair' operator. Each ribbon will pick random uv box. It helps differ the texture look.
- Added 'Curve Resample' - changes number of points the curve is made from.
- Added options 'Select Tips', 'Select Roots' under Blender 'Select' menu (visible during curve edit mode, on bottom header bar)
- New option 'Ribbons from particle hair with children' - gives better result compared to child particles generated by build in blender child particles (more even distribution, better aligning of child ribbons to surface). Great for short Hair.
- Resample - more options, and keeps curve tilt and rotation.
- 'Particle Hair From Grease Pencil' strokes painted in grease pencil, can be converted to particle hair (with some options available under f6)
- 'Flip UV' option in preferences - if enabled random strands will have uv's flipped in X-axis
- ability to add 'random vertex color per ribbon'. Can be also used on non hair meshes, to add random ID vertex colors per loose mesh parts.
- ability to add presets for 'Ribbons from particle hair with children' operator
- added "Smooth scale" - similar to 'Smooth Tilt' but smooths the radius
- added 'Edit curve profile', 'Close Curve Profile' - if you want to adjust curve bevel profile by hand
- ability to taper roots of curves ribbons (previously you could taper just tips)
- added 'Placement jittering' F6 option for 'Ribbons from particle hair with children' button - helps a bit to get more uniform child strands distribution.
- ability to preview hair texture directly in curve ribbons stage. See video explaining new feature: https://youtu.be/gtbhmYEKGZE
- linear deformer tool - for curve modeling can be downloaded here: https://github.com/JoseConseco/mira_tools (how this tool works is explained in video above)
- hair resample and simplify operators preserve material order
- added options to remove, resize, reset - uv boxes when using "Draw uv area for Hair" operator in imaged editor window (found under spacebar).

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)
