Create Realistic Hair in Blender with Geometry Nodes!

Hi everyone, I wish you all a very happy 2023! I've been away for a little while celebrating the holidays, but I've been working on this tutorial during the time off. I read your comments and take your suggestions very seriously.
So, here's a tutorial on how to use the new hair system combined with geometry nodes to create realistic hair systems! To help you save the time of creating your own geometry node hair setups, I added my .blend hair system file on Gumroad that you can download for free. It contains the Geometry Node setups that you can use to customize your hair systems quickly and easily! Hope that helps :)

Thank you so much for the support! Would you like more hair tutorials or more info on geometry nodes? Perhaps a combination? Let me know! 🖤

[@calebnwafor2549]

Both please

[@NinoDefoq]

@@calebnwafor2549 Nice 😜

[@AbdulHaseebSIME]

can we animate hairs. like curling hairs on a cylinder shape? do i have to rig whole geometry of these curves can be animated using shape keys etc?

[@yi8634]

Yes, please! I would love to learn how to make a pony tail with straight hair!

[@NinoDefoq]

@@yi8634 Awesome! I'll try to get into it 😇

[@pixelricebowl]

Great tutorial! Also thanks for including the geometry node setups. It makes understanding these features a lot easier.

[@NinoDefoq]

Thank you! Glad it helps 👏

[@Товарищ-777]

You said, "You now know a little more about how it works." Not really. I now know a lot more how it works. Thanks for your informative tutorial. Thank you very much, sir.

susan´s hair lookin like griffith´s from berserk, great tutorial

[@LIFEisShort4016]

I LOVE YOU NINO!

[@NinoDefoq]

Appreciate you!! Thanks!

[@thedrawhawk]

Wow, great tutorial!

[@NinoDefoq]

Thank you so much!!!

[@UniBlend_Art]

Thank you for the tutorial Nino!

[@NinoDefoq]

Thankyou kind ser! 😇

[@johndeguzman5516]

Thank you so much for the video and sharing the node setup.

[@NinoDefoq]

Yw and thanks!! 😇

[@firsthill3310]

I had a feeling you were going to do this. 😀Thank you very much !!

[@NinoDefoq]

😜😜 Thankyou!

[@babyitsnatural]

I like the way he says, "Select the monkey"

[@toyaleejb7714]

Was literally thinking of this a day ago when I saw this! KZbin do be reading my mind

[@NinoDefoq]

😂KZbin has its ways!

[@tedonieuwenhuis6707]

Thank you so much, I learned again

[@NinoDefoq]

You're very welcome!

[@jorari71]

Amazing! It works like a charm. I will crate a reference when I publish my work using yoyur geonodes for hair. thank you very much!

[@NinoDefoq]

Glad to hear that, awesome! Thanks 😇

[@denizcarta6805]

great stuff, but can you apply hair physic dynamics to this hair after you are done , like the hair in the particle system ?

[@AlexOotzaAkaSharpy]

You are a hero! Thank you very much!

[@NinoDefoq]

Thankyou! 😇

[@Boipelo]

Epic! Thank you!

[@DCCXXV]

You deserve way more subs wtf! Also your voice sounds really nice what mic do you use?

[@NinoDefoq]

Thank you so much! I use a Rode NT1-a for recordings :)

[@svrvphimprod]

why is hair in cycles so thick for me?

[@NinoDefoq]

You may have forgotten to add the hair thickness geometry node system. That one allows you to tweak the thickness.

[@Logically_Fallacious]

Tyvm for the share... My astronaut''s helmet just got hair!

[@NinoDefoq]

😂 That's amazing! Glad it helped

[@biggestonee]

Thank you!

[@D3LB0Y]

nice judge wig

[@NinoDefoq]

Cheers 😂

[@halim4168]

Thank you so much for this! keep going 👏

[@NinoDefoq]

Thank you sir!

[@dicesuki4286]

Thanks for this!! it would be cool if you could make a ponytail using the hair physics in blender

[@NinoDefoq]

I'll keep that in mind! Thank you 😇💙

[@serpentstruth]

And thank you so much for the blend file. You accept donations?

[@elliot4727]

Just wondering if using this system on a character (potentially two characters in same scene) will make my render time go up exponentially? Is there a way to bake it or something to make it quicker once you have the hair modeled the way you like?

[@MagicSwordFilms]

has anyone been able to get their hair systems to work with shape keys? It looks like it works well with rigs, but I usually rig my characters face's with shape keys and those dont seem to work for the mesh deform modifiers

[@BlenderVIzzLab]

Brooo 😭.... I want hair geometry node but unable to purchase it , I am beginner and trying to learn blender from your videos ... but i have no bank balance. please help ....

[@TheAptimn]

This is great! Yet I still struggle with making the ends of straight hair look natural. Maybe there is a need for a slider to decrease the uniformity in hairs' lengths and introduce some more randomizaion at varying depths into the lengths. Otherwise, when the lengths are even (or a even slightly too uniform) they start looking like a "clamped toothbrush" of a sort at the tips.

[@NinoDefoq]

Thank you! And for the feedback! Feel welcome to make all the changes you'd like! I may revise it in the future as well 😇

[@jorari71]

I have a question/ request: I am working on my character and I realized that after creating and combing some hair, I would need more smothing hairs/strands, because I got lack of control points. the question is, once I 've created my strand, how can I increase the control points in order to avoid these long straitght segments ? Is it possible to add a GeoNodes modifier in the stack in which I can increase the number of control points to my strands? thanks in advance.

[@Maxie962]

Could you please upload the blendfile somewhere more accessible? gumroad literally doesn't work for me.

[@michaelfae]

5:03 When I use the density brush my hair always appear very short....shorter than the hair I added with the add brush and so far I can't seem to find a way to make them of equal length. What do I do to fix this?

[@NinoDefoq]

There is an option at the top when you are in the density setting that should say something like "shape". Click it and then you can select length. That will make the new hairs match the length of the existing hairs.

[@michaelfae]

@@NinoDefoq Oh man! What a lifesaver! It works! Thanks so much...subbed

[@NinoDefoq]

@Michael Fae No problem at all! Glad it helps, thankyouu!! 💙

[@synapse349]

Now how do you animate this new awesome do so it behaves like particle hair?

[@NinoDefoq]

Easiest way is to convert the hair systems into a particle system once you're finished with the geometry nodes. Apply the geometry nodes and go to the hair sculpt mode, and convert it to a particle system there. You can then proceed to do how you usually do it with particle systems!

[@martywilson-nolen8023]

Im having trouble exporting my .obj into fusion with the added hair.

[@calebnwafor2549]

But how will the hair respond if the object itself is a collision object

[@NinoDefoq]

What is the idea?

[@npj5578]

Great video, really helpful. Do you know of a way to create sub clumping? For example, having clumps within clumps using geometry nodes. The only way I have seen is using 1 clump per guide which isnt ideal as it requires a tone of guide curves to get something looking natural. Thanks!

[@NinoDefoq]

Thank you! I'm not sure what you mean, do you have an image example I can check out? :)

[@npj5578]

Basically as it stands. You can only have 1 clump per guide. But it would be nice if you could add layers of clumping and dictate the frequency with a slider regardless of hair guides. You could then layer it up so you have say large clumps, followed by fine clumps. It just makes grooming much easier not having to hand sculpt so many guides.

[@tuxgirl]

Hello, are these geo nodes able to be used commercially? Or only for personal use? Thank you!

[@NinoDefoq]

You can use it for whatever you want :)

[@nykato3569]

Can you turn this into card hair?

[@nykato3569]

Like what I mean is the fact that if I can optimize the hair so it doesn't have a ton of vertices

[@NinoDefoq]

You can use Resample Curve nodes to change the resolution of the curves. To change the resolution of the circle of a hair strand you can check out node groups that are connected to the profile section of the curve to mesh node

[@robinnightfall6680]

I don't know how to animate that stuff

[@Levi-samaa]

I guess it’s not able to animate with geometry

[@lonewolf-vw9wf]

the hairs look like noodlles, what to do ??

[@NinoDefoq]

Change the thickness settings in the hair thickness geometry node setup ^ it's in the tutorial

[@serpentstruth]

Hello, do you know to animate this hair?

[@NinoDefoq]

What kind of animation are you looking for? You can select your hair, go to convert and convert it to a particle system. Then you can enable hair dynamics in the hair particle system and have it flow with your animation.

[@serpentstruth]

Thanks, that’s what I was thinking. I also thought about rigging but hair physics is probably just better.

[@loyaltyf278]

what blender version are you working on??

[@NinoDefoq]

In the tutorial it was 3.3. Now I'm using 3.4

[@loyaltyf278]

ouuuu, okeiii thankss sirr, really loved it! oh yeah, one more thing, can we animate or rig the hair?? how??

[@llovingkenny3780]

What type of gpu is recommended to run these nodes?

[@NinoDefoq]

I don't have a strong suggestion as handling instances will use a combination of RAM, CPU and GPU. You can check out opendata.blender.org/ to find GPU benchmarks for Blender. www.cgdirector.com/blender-system-requirements/ Shows some minimum and recommended requirements and I'd have to agree that 4gb of VRAM is needed for a lot. I'm running 8gb vram myself in a NVIDIA GeForce 3070, but for a hair system like this that's quite overkill nonetheless. Hope that helps!

he made her so beautiful that by the end Suzanne is NSFW guys just giving you a warning

[@NinoDefoq]

Lol 😂 Thanks

[@spittingame4241]

It be honest, this seems unnecessary and more work than it had to be.
