Hair Info node has been renamed to Curves Info for those who were confused like me.

This is amazing, how on earth did he figure it out?! Things to note in NEWER VERSIONS:

To thicken the hairs - its under render --> curves (not hair) --> strip.

Mix rgb is just mix and change float to color.

Hair node is curve tangent, like someone mentioned below.

Turn world strength way down (mine is .5)

In particle edit, make sure children is checked and steps are 5, under "tool" tab.

Try different light strengths. Pay close attention to what he does, the light is really what makes work.

Looks like it works up to 3.6.0. I swear it wasn't last night but now it is 😢
Whatever version, you use, make sure you can find "shader to rgb" and "specular bsdf" before you start.

In 3.2 they changed the Hair Info node to the Curve Info node.

I HAVE BEEN SEARCHING EVERYWHERE FOR ARCANE STYLE TUTORIALS! AND YOU GUYS (OUT OF EVERYONE) WERE THE ONES TO DO IT! Thanksss

In case anyone else was having "weird" behavior with shadows: remember your WORLD COLOR and STRENGTH contribute to illuminating Diffuse BSDF.
I had to tweak the world shader with a Light Path node by mixing a 0 strength background in using "IsDiffuseRay" as factor.
That's because my 50% gray strength 1 world was lighting the hair, thus not giving the shadows in the video.

Top tier tutorial as always LBS! I am astounded I'm learning so much for free and looking forward to part 2!

A warning to future historians, this tutorial breaks in Blender version 3.2.0 around the 18:30 mark, the specular highlights do not show up the same.

For anyone who can't get the hair children to display in particle edit mode in Blender 5.0, unfortunately it's bugged. You'll have to use a different version of Blender (5.1 fixes this bug and is already released)

You have to enable the children option in the top right corner of the window before painting your strands, then the preview is working in "Particle Edit"

How does he get a bunch of strands to show up once switching from 'None' to 'Interpolated' at 4:15? When I do it nothing happens... EDIT: Fixed it. They were invisible in Particle Edit mode because I needed to press 'N', go into 'Tool', go into 'Viewport Display' and tick the 'Children' tickbox.

in blender 4.2, if u r having issues with the translucent node, plug a value with 0 to the thickness of the Material output node.

If anyone cant find the mix rgb node, just add the "mix" Node and then change the setting from float to colour which will then turn the mix node into the mix rgb node

We need a 4.3 tutorial T-T

Bro i ain't gonna lie i saw everyday different way to modelling a hair on Youtube, but this type modeling blowing my head that's so interesting way. Thanks for your effort.

Absolutely DOWN for this! Can't wait to watch, thank you so much!

Their back!

Me watching this: c:
Blender Foundation: Let's change all that...

If you go into Particle Edit mode and your hair disappears, hit Options in the top right of the viewport and tick Children, and that'll show the clump you're working on.

Amazing video.

yooo YOU GUYS ARE THE REAL MVP OF NPR  BLENDER COMMUNITY

WOW. I can't even begin to say how helpful this is!! Thank you so much for all of this research, and putting it into a cohesive tutorial for us all to learn from (the way you broke down the process for creating the hair was mind-blowing!) I will definitely be using this for my projects. You're a lifesaver!
