hy i want some movement is the hair is it possible by any chance pls tell me

[@xanzuls]

Absolute game changer. Thanks Blender Devs and Simon.

[@stout8529]

I guess if your playground is just blender, it might be a game changer. Otherwise it doesn’t offer anything special, unfortunately. As a professional character modeller and grooming artist i’m always looking out for new grooming tools cause the task is pretty complex. It doesn’t bring anything new to the table, tbh. Tools like xgen, ornatrix, yeti has been doing same stuff for 10 years by now… and then some.

[@stout8529]

@@xanzuls something tells me that you are not familiar with neither xgen or the other tools I mentioned. Ofc you can display all the hair with full resolution in the viewport and groom interactively. Ofc there are many different ways to sim groom. Not gonna discuss this any further. Just learn how to use the tool and you’ll get it. All the tools I mentioned are quite fast, actually. Never experienced any serious lag or anything. Cumbersome is maybe your tool handling skills. The speed is one thing Blender tries to offer, but this is actually a disadvantage. Pro level grooming is very… very difficult task. One might even say it might be one of the most difficult task on the character/creature pipeline due to the complex nature of different hair and fur types, hairstyles and so on. Pretty much all animals have hugely different types of fur and one specimen can have about 10 different types and layers. Not a drag and drop task if you want to nail it. High level grooming requires a wide range of tool capabilities and techniques. Xgen might be THE most powerful in that regard. At least what is available to the public. If you are counting out Xgens SeEexp, you are missing at least half of the thing. And it tells me that the level you are working on is not the highest. In VFX the standard is damn high, Blender tools just won’t cut. And that separates the best from the rest. You just have to put in some serious manhours, otherwise the outcome is nothing special. And that’s what bothers me regarding Blender. It doesn’t take it seriously, just a toy to impress novices. Novices buy tiny addons and impose themselves as a cgi wizards. Yet, the work is just a lousy hackathon in strong majority of the cases. In games, the standard is not that high as in VFX. But there are more capable methods for UE grooming as well. We’ll see, where Blender can end up, but at the moment it’s not on the cutting edge yet, I’m afraid.

[@ClaudioMalagrino]

This is impressive! Working with hair in Blender was always so difficult. I can imagine the possibilities now!

[@davidedozza]

😲 This made my jaw drop... Very useful and well explained video, thank you! 🙏

[@fakecubed]

This is such a great use of the assets system, and these node groups you've given us are fantastic. Excellent presentation on it, as well. Hopefully we get some simulation node assets in the future. I'm quite a capable geometry nodes user and I've been experimenting with simulation nodes since the sim node branch got its start, but having some drop-in stuff for basic physics sims would be very nice as a time saver, especially if they are as well thought out as these hair node assets.

[@QueenDoot]

It used to be called "Blender Cloud", where we'd post tutorials and such. Now it's dedicated to show behind the scenes of the short films by the Studio, plus workflow and pipeline tutorials such as this one. There are 3 official Blender channels: * www.youtube.com/@BlenderOfficial (main, for news, conference, etc) * www.youtube.com/@BlenderDevelopers (for developers) * www.youtube.com/@BlenderStudio (this one, for studios and creators)

this vid has made me more comfortable using geonodes and il be happy to experiment more with geo nodes in the future also any vids on how to understand how nodes work or what they need in order to function?

[@fakecubed]

Geometry nodes is an extremely popular topic with the KZbin Blender community. Just do a search here for Blender geometry nodes and you'll get a lot of results. Add search terms for specific areas you're interested in, or just beginner tutorials.

[@Reaching1]

how to change the length of the fur ? Tried this on a wolf model and the hairs are like 2 meters long and I have no idea how to change the length to a few cm for a nice fur coat. do you have to change the length of each hair strand in sculpt mode with grow/shrink? that's impossible to do, and takes ages.

[@robm509]

I am using 3.5.1 and trying to follow along to this tutorial, but @2:20 - Snap to Deform Surface in sculpt mode doesn't work for me when rescaling my surface. I have no idea why.

[@marcogamarra4219]

thanks very much for this teach. And nice done, the Vivien Lulkowski hair

[@alexarockman3999]

THIS VIDEO IS SO GOOD!!!

[@kunemann]

I love Geometry Nodes and GeoHair! It's the best thing that's been added to Blender since Eevee in 2.8! :) Now I also know that the Surface Defomar Modifier always has to go to the end. I wonder why this doesn't happen automatically, like with the Multi Resolution Modifier, which always has to be first

[@charlytutors]

Nice video. Thank you!

[@juanp.5364]

Love it. The only problem I am having is that you need to work with too many hair curves to get good results. Maybe this can be solved deep in the geo nodes.

[@williamlacrosse9389]

Is this blender or houdini grooming! My eyes are cheating on me!

[@danialsoozani]

I've installed it today and saw your video, it is amazingggg!!! I had a problem today, it was rendering very slowly!! the samples were dying to go up 1 number! was it cuz I did it on default cube 2x2x2? thanks for the great tutorial. but in eevee with compositor view in layout mode, I created a very stunning fur and grass!

[@yeroslav11]

This is absolutely amazing 🤩 are there any plans for allowing us animate these node as well?

[@silentlady408]

absolutely fantastic !

[@Layston]

How do you change the length of the fur? Having trouble figuring it out

[@Haniverse_00]

Is there a way geo hair imports to Unreal Engine? If it's not, any way converting to mesh or something? For using it in game engines

[@AlexisRivera3D]

CTRL + A -> Visual Geometry to Mesh

[@cuentaaspire1]

@@AlexisRivera3D this seems to create a lot of vertex connected by edges, is there a way to turn this into some sort of geometry? or even better, turn it into a particle system so it's compatible with the groom system inside unreal?

[@666aisha7]

maybe this is stupid but why dont just add the fur curve to the mesh u want to use, from the start? im doing it like it and it seem allright in blender

[@Bingbangbong28]

[@josiahgil]

Can this be animated? Any tutorials for hair animation using geometry nodes.? Thanks

[@hondenbraaksel]

Looks great and works quite well! There is a problem not being able to groom some more complex surfaces and cant find out how to make that work. Anyone got tips?

[@musings_from_eternalmoor]

I have used interpolate density mask and picked a vertex group for my hair/fur. This works fine, however, how do I move the "strays/curves" that are distributed across my whole head to the vertex group? Snap to does not work. I guess I can manually move them, but what would be a faster way?

[@piotrrywczak]

I would love to see tips on optimisation. It's difficult to work with 15-20GB of RAM usage per character with Curves.

[@VentelHD]

I have some troubles with interpolation. I understand now I need to do masks, but I would rather to just interpolate between the existing curves like in particle system.

[@sridharerror]

Blender always king 👑

[@leinku]

The video only demonstrates a small part of the model and it runs smoothly, but I want to know if it can also run smoothly when used to create a complete effect. Has it been improved in Blender 3.5? In previous versions, when the number of hairs was increased, it ran very slowly, and adjusting each parameter would make me wait. The old hair system had an advantage in speed.

[@PabloVazquez]

It's been improved greatly and continues to be improved in every release, thanks to more parts being done in generic/procedural ways and added multi-threading to more nodes. That being said, it can get slow in any system, at the end of the video Simon shows how to use a mask modifier in the mesh to preview a small part but in full detail.

[@IbrahimYounes]

@@PabloVazquez Hi Pablo, couple of people asking about texture colors reflecting on hair, is it possible? here is a copy from one of the questions: would much appreciate it. "Please explain how would the hair inheriet the colors on the surface the hair are associated with?" I never able to attend your live Monday sessions, always at work! I do watch the reply though, thanks for all the hard work ! and for the entire blender team !

[@sleepykittyMMD]

for some reason I don't have that second option for fur. it only gives me empty fur.

[@Hanaconda_Aquaponics]

I don't have either option come up for me. I don't know what I'm doing wrong. This is a fresh install of Blender, so it shouldn't be out of date.

[@ksunnywazowski]

amazing tutor thank you so much!

[@antoniopezzella2174]

thank you Simon, that's great, is there a way to use this kind of workflow for lower poly hair to use in game engines? I imagine something like generating a lot low poly planes with an hair texture and then depeding on the planes lenght/width , the UV position would swap to take the shorter/longer hair texture. Essentially, it would be great to have a similar hair creation workflow but optimized for game use.

[@metamesh1]

that looks great, but does this mean that hair is UV dependent? that can be kinda destructive sometimes? still, great stuff!

A quick noob question cause I cannot watch the video right now (work tomorrow and need sleep), but what can this be used for other than movies? Can I use it for games? Like convert into "mesh/planes" or something that could be used inside Unreal Engine 5?

[@666aisha7]

im testing it in a cat ears mesh and i think it looks fine, im pretty sure if i knew more i could make an amazing fur rn, but im not that sure if it would work well in game since at least in my pc it goes super slow, my plan is to test this fur on a mod im making using ue4, i will let u know how it works when i try it out

[@wonderboy75]

This is Niiice!! Question to the Blender Community (I'm an old 3dsMax user here, quite inexperienced in Blender): How do I change the number of decimals displayed for the hair thickness? Even if I change the Scene-> display units to mm I only see 1 digit in the input window, no decimals. How do I get more decimals?

Maybe change the unit system to none, it's under scene properties.

[@artup.yourlife466]

hello, i am not able to move the hair in sculpt mode plz help.

I do have a question. I probably missed the answer, (im trying to make a cat photoreal type,) but making hair with particle system is very heavy. With geometry nodes, making the same thing, won't be that heavy or will not require much Vram has particles? I don't know geometry nodes, but I wish to learn.

[@matthewcowdery4277]

Is it possible to color this hair/fur based on the object its "growing" out of? I'd assumed it would be, since it already is using the UV of that model to determine hair placement, but I couldn't find out how...

[@hungry_pig]

Is it possible to export this to unreal engine??

[@saintelmo5590]

Is there a possibility that Blender might be able to get the Hair Curve system to have a Geometry function like Bezier or Path Curves without having to rely on the tedious Geometry nodes? In other words, to be able to extrude from Hair Curves as one would a Bezier or Path curve using the Object Data Properties instead of Geometry nodes, while still retaining the grooming functionality of the Hair Curves system? I think that if there were any one node or node system that would make this truly effective, it would be to be able to align the extruded Hair Curves to the mesh to which the Empty was applied.
