- [New] Animal Fur Groom for UnrealEngine 5
A series of tutorials exploring the creation of
Animal hair and fur using Unreal Engine 5, Blender and DazStudio.
In this tutorial I show how to convert strand based hair,
in this case, created in DazStudio modified in Blender and
use it on a character in UnrealEngine 5 using Groom hair.

I hope you find this tutorial useful.
Any questions or suggestions ? Please leave a comment below.
Thanks to @patrikbaboumian for convincing me to make this tutorial.
He has a lovely beard.
Thank you very much . Please, I trust you and your good teaching style, and I hope you will respond to my request, which is the second time I submit it. I need a step-by-step tutorial on how to create a material parameter collection for a human character that turns into a monster or ghost by changing the material of the face, eyes, and body in Sequencer.
Please I hope you will pay attention to my request this time
I already did this ?

Hi sir when I enable simulation hair is not stucking properly with mesh although I bind the alembic groom with the skeletal mesh but little hair not sticking with mesh when animating please give me some solution...?
this is amazing! how were you able to import the walk animation inside Unreal? Is there a way to animate the dog's rig within Unreal?
man after this long time you come back what a intro to a video you always take your time to up the production quality even just for tutorial. big up
Fantastic tutorial! Been waiting for someone to explain the "Blender hair texture uvs to Unreal Engine" process for a good 3 years now, thank you!
Wow, I never knew unreal could look so good. Awesome job!
Oh, I'm so pumped for this! Thank you for taking on the challenge :) I haven't watched the video yet but I needed to leave this year before I watch :)
Love this. Needed this for a cat
You’re amazing! 🦾🦾🦾
Thank you!
WOW!
this helped a lot!!!
EXCELENTE!
@Jobutsu many thanks for the guide ,I have the model and fur inside UE, worked floaelessly, only fix i didnt see was the white eyes. Also the anims when using some of the D8 anims you need to scale the model down and then use a null node to rescale. The problem is I cant seem to get the anims looking good in UE there always appears to be a joint issue. The anims are fine in daz but when exportng to UE they look wird at the joints especially the fron leg joints.
My guess and that is all I can offer, is an artefact of the scaling problem.
THIS IS Cool
Thanks so much for shared this great tutorial!
I have one question, when you enable the geometry cache i can import a alembic file for the animation character?. i mean supposed if my character mesh have a animation in alembic format.
I don't understand exactly what your question is, in the context of this tutorial.
But I import Alembic character animation into UE on a regular basis.
Hello, great tutorial. I had a couple questions because I keep getting errors that I'm not sure how to fix. I have a very dense fur that I'm trying to import, so splitting it up in edit mode is a must, otherwise I'd be sitting here for hours. However, when I import it to Unreal5, you can very visibly see the cuts I made and it ruins the whole thing.
Also, my fur was made in Blender. I noticed you mentioned in another comment this tutorial is mostly for fur from DAZ, so I was wondering, to simplify my process, what isn't required here since my fur was made in Blender? From my understanding creating the surface_uv_coordinate and all that is for the DAZ process, but am I able to skip any of this? Thank you!
Fur made in Blender already has the root_uv. As long as your fur was created for your character, you should be able to just export to UE5.
Can we use this technique to apply to a fur coat? Maybe a tutorial for fur and fibrous clothing to unreal? Thanks for the awesome tutorial
Yes of course! But this tutorial is for DAZ hair without a root_uv.
If you create fur from scratch in Blender it generates a root_uv and so yes, I do not see why you could not create fur clothing.
Thanks!
Welcome!
I wanted to do something similar with Reallusion hair in the future, if that interests people.
@@Jobutsu That would be great!!!
Great tutorial! One question. I'm following all the steps, except one - I have not a skeletal mesh but an alembic animation in cache, and somewhy binding is giving errors, saying that UV's are missing. BUT, when I'm turning off root UV's on groom, everything is working fine. Maybe you can tell, why it's working that way, because now I can't use textures on my groom because of absence of UV's. Thank you!
I never tried binding with an Alembic cache.
Maybe your Alembic was not exported and imported with UV's ? (source:guess)
thank you! DO you know wich setting are needed if my character has both joint driven animations but also blendshapes?
Can you be more specific ?
AMAZIN VIDEO, so helpful. But i got little error and cant handle it. Any idea? After all those steps Im importing groom into unreal and the fur from head firstly i thought its gone, but when i rotate it was looking like flipped or something like clipping on groom. And cant handle this. ANy idea?
It is difficult to say without a visual reference.
Hi.. perfect.. and questons: 1. First at all, your link to dog is only the fur variations, the DAZ DOG 8 is needed first, right? 2. Is the body (walk) animations included with this asset? It's not described in product info. Thanks
Edit: The description has been updated.
which of the 'Groom Exported' Files do I select to 'install' for Blender Preferences? I can view the 2 x folders _pycache_ + PyAlembic and then the 7 .py files .. I have tried them all and then each seperate .. but alas none will install and take me to the 'activate add-on ' check box
I have not kept up with the development of this plugin, i do not have an answer for you at this time.
878K strands and 4.5 millions vertices is a bit much for real time rendering. Maybe just a case for movie render only projects. Should try reducing amounts of strands to 100/200K and playing a little with a larger root thickness to cover more of the body's base mesh per strand, it usually works well as the model already came with a pre fur texture under it.
Thanks for the advice, I am always looking for ways to improve. hopefully it will drop the temperature in my office by a few degrees too !
Hi there, thank you so much for the tutorial! I just have one problem, it says that the add one misses the "pyalembic module", the one that I see in Patreon of the guy. How should I install it? (it's not a file zip)
Solved it, for whoever had this problem: when ading the add-on, click on install dependecies in the preference menu and install apart the WHL file in the Patreon
do u transfer the animation from daz to unreal through the daz plugin or is it fbx imported to unreal.i am trying to send animation through the daz plugin but the face gets deformed ...any tips ?...i have selected retarget source as the dog skeleton
I stopped using that plugin, I have no idea where the developers are going with it but it has not worked for me for a long time. I just exported as FBX and checked Animation. then import into the engine.
Nice bro😊 dog trot animation from daz right?
Yes, slightly modified with physics added.
Thank you very much . Please, I trust you and your good teaching style, and I hope you will respond to my request, which is the second time I submit it.

Please I hope you will pay attention to my request this time@@Jobutsu
Thanks this is really useful.
I have Made amazing hairs for metahuman, unfortunately I have lost the project file, I only have the groom usasset file in UE with a wrong pivot point and position won’t match MH head when I bind the groom, i am getting crazy, do you have an idea to how to fix it?
The only thing I can suggest is using a Metahuman with the closest proportions as possible to the original that the groom was bound to.
Rebind to that, if ok then use it as the source from your new Metahuman binding.
Thanks @@Jobutsu I've solved with a groom exporter plugin :)
Now everything is ok thaks for all your work, it's really inspiring for me.
20:01 what are those stripes on the leg? (like ripple lines or sometimes like lattice). What can be done with them? Have that problem with my panda caracter, in my case fur came from maya yeti. I'm usually rendering with 64 or 128 spatial samples, anti aliasing checked to None.
If you are taking about what i think you are,maybe improved lighting could help.
I did not render this with such high spacial samples and I think, I also had anti aliasing set to none.
de donde sacas el rig y las animaciones
Thank you so much, but how I make this dog speaking? I try to figure but I could not >> I hope to find the solution with you and again thank you
That is a complicated process.
Ok, thank you for your reply :-)
I'm following this for a horse model I have fur for and my goodness does Blender take its sweet time at every step. Are there any ways to speed it up or do I just need to be patient?
It is a complicated task and for whatever reason, Blender does not seem to utilise all available cores for the task.
I will look into it.
@@Jobutsu Blender finally finished the conversion of the horse hair fur mesh to hair curves today and oh wow it looks so good! It was worth sticking with it even though it took a long time. Thank you for this tutorial. I have fuzzy horses now because of you
I have no button Export
Great Tutorial! unfortunately i had an error when i tried to export using the addon: It says "AttributeError: 'NoneType' object has no attribute 'location'" Anyone can help?
I can not repeat this error, did you fix ?
after reinstalling the addon it worked properly! Unreal Engine wont detect my Root UVs though. I am pretty sure i connected the UVs in Blender the right way but maybe there is still an error. Do you know where I can fix this problem?@@Jobutsu
Is this Blender 3?
yes
Nice but why not use Gfur?
Never heard of it.
As I understand it, GFur is for creating fur from scratch. This method is for converting already made fur to a file Unreal Engine can use
This is correct.
I should have been a little clearer in the the video but it was lost in editing.
The actual purpose of this tutorial is to create a root_uv for hair/fur that does not already have that attribute.
i am from germany and i find the word groom to be very confusing. if i try to translate it, its more like the "taking care of animal hair", the pet groomer, or the child... bad thing with this word. but why its groom in this case? isnt it just fur or hair? :D my brain wants to know!
Groom in English, is to style, clean or brush hair.
Maybe create a hair style ?
I did not name it.
confusing because its something you do, its not an object like hair or fur. thats why exporting my groom into unreal is a little odd, for me :)@@Jobutsu
where this dog 3d file please
Link to the product is in the description.
Sorry but all the softwares out there can do a better job when it comes to fur, UE5 feels like it´s not production ready, the workflow is unclear, works sometimes... not worth it, you can do it all in blender and render only your BG in Unreal, thats the only workflow so far, passes don´t work with fur, you can't comp it, its a nightmare, thats why all you have is the meerkat, a big production from a big studio, nobody else is using it.
Use what you must to get the job done.
ok so its not a skill issue. unreal hair rendering is actually dogshit. good to know. pathtrace looks softer and nice, but lumen is crap. but i cannot justify using it for its render times!
