---UPDATE---
I just exported a groom from blender 3.6 to unreal engine 5.2 and it worked perfectly. However it did not work straight away. I did have to uninstall the older addon and re-install the latest addon (2.3.1) from the Unreal github and I had to enable "python remote execution" and "pre compute skin cache" for it to work.
If anyone has any problems just restart Unreal and toggle off the groom and python plugins and the remote execution project settings as well as pre compute skin cache and then toggle them back on again and try again. I found it worked after I did that.
Works great.
So, it is not working on 3.5 +5.1 right?
@@lucianodaluz5414 I see no reason at all why it would not work n 3.5 + 5.1. But no I have not tried it.
@@DirkTeucher Seems like it cant "understand" the groom import plugin is already enable on UE " Please enable missing plugins in Unreal: Groom. Or disable the Groom import setting.
"
@@DirkTeucher I did some tests and it works but only for simple nodes, it doent work if you use some custom properties
@@lucianodaluz5414 I've found a guy on the Unreal forum that suggested to turn off the Unreal plugins (Alembic Groom Importer and Groom), restart and then activate them again. I had the same issue and doing so fixed that error for me
This was the exact tutorial i was looking for! Thanks
This is outstanding. I've tested with Blender 3.6.0 alpha and UE5.1 and it worked both with particles and geo hair. Thank you so much for this update.
hi, do you apply the modifiers of the geometry node?
For me it doesn't work.
@@noosman16 I exported without changing anything. Make sure all assets are in the Export collection. Can you please tell me what is going wrong? Perhaps the developer can walk you through.
@@LFA_GM Its works with geo hair tool???? 🤔🤔
Thanks for the tutorial! I am having an issue with the hair not sticking to the head when I move the character. I have previously used alembic export for particles which works fine when I use 'binding'. It seems my blueprint wont accept the 'groombinding' object I made for the hair. Does anyone know how to fix this?
Amazing ❤
Do you know by any chance how to export to another program? like Marmoset?
HI. I tried to export it and the fur that you can add with shift+A and it only gives me like 10 particles when i exported it. I tried with the empty hair and then added some geonodes on top of it and then it at least exported but it exported with only the hair that was added before the geonodes addition. Basically the geonodes did not export. Is there a way to export the hair with the geonodes?
Hello @DirkTeucher, is there a way to combine multiple grooms into just one for export, and would it follow the mesh/skeletal, sorry I'm quite new to unreal and I'm any help is much appreciated!
Quick question: Does this work with deformed meshes directly in UE? If I have an animated character with Joint and Blendshapes animation exported as an FBX for example.
How did you made your groom in blender ? did you use any plug in or blender new built in hair system ?
Before you can access the addons you have to register your Unreal engine account with the Unreal GitHub account and request connection between your Unreal and Github ID's . The link is in the description.
It doesn't work for me, even after I've linked the account. In fact I cannot find that plugin on the epic games page of github even searching for it. Could you check if the link is still working, please?
@@CM-fx1tp Read the description I just checked the link and the addon is there. You need to request access ... see the first link in the description. No worries though. If you are still stuck just export as Alembic from blender.
Are those hairs individual hair strands or are they made up of planes with a transparent image?
export -> send to unreal option is not showing up version 2.4.1
Is it possible to use this groom, this hair you create with particle system in blender like a game ready hair? I mean giving it physics and animation and all that without making you pc crash or slowing the game.
In Unreal you definetly can, I've done it before and it works great
Great. Does eyebrows and beard follow meshdeform when character do some expressions, bro?
You have to bind it inside Unreal. It is pretty simple.
super useful thanks mate,
Any idea how to get it to animate? trying to do a furry critter and cant get the animations to work :\
Have somebody solved problem with low subdivision curves after exporting in Unreal ?
weird question. Can you color the hair based on UV coordinates?
I'm trying to make the colors match the maps I made in Substance... and it usually works in blender, but it just doesn't translate into Unreal. Any tips on how to do that?
You can color the hair based on the length from base to tip. Use the lerp node to interpolate between colors and search for hair nodes in the material editor to use the length attribute in the alpha. You also need some scalar parameters to adjust things. If you preview the output of the nodes individually you might be able to figure it out. Or search for more info on those nodes.
@@DirkTeucher ill DEFINITELY need to search for more info, but thnk u so much for the tip! its the fur of an animal... so don't know if this applies, but ill give it a try.
if you can think of some vid that explains what you said, drop a link :)
Hey bro, do you know any way to export models with texture from blender to prusaslicer?
I tried some things but nothing works, or it exports just the head (the model I created in Blender is a head with hair) or it gives this error "Loading of a model file failed". The result I'm looking for is the complete project, but the hair never comes together (in this case, the head with hair).
Sure you should be able to convert the hair to polys there are videos on youtube about how to do that but I would expect a lot of problems printing with PLA and a resin printer is more likely to be able to handle hair even if you thicken up the strands I think FDP / PLA will have problems. I will take a look this weekend and try to do a video to answer all the questions people are leaving about hair as this video gets a lot of questions.
This seems to be working well enough to at least get a simple groom to Unreal, but one thing I'm noticing is that it isn't carrying my Geometry Node modifier edits over, even if I apply them prior to exporting. Do you know how I might be able to ensure those carry over to Unreal?
applying modifiers worked for me ue 5.1.1 blender 3.5
Hey, thank you for this tutorial! I've tried with Einar demo scene from Blender 3.6 to Unreal 5.3 with latest addon (v2.4.3) and worked well. But I'm not able to make it work with a simple project: create Blender empty project > add uv sphere > add curve/fur on that sphere > push assets to unreal. The result is very different from the original... anyone experienced this?
This is super cool, but it doesn't seem to carry over the subdivision settings, so the hair resolution is as low as it can be? What can I do?
Noticing a similar issue, but with pretty much all of my important geometry nodes. They're not custom nodes either, so I'm unsure why this is. Did you figure out what caused this for you?
same problem here@@SadPanda449
this is insane how easy they make it instead of exporting individual alembic........dammnnnnnnnnnnnnnn
Hi, this is the video I was looking for ! But I have a question because I see a lot of people having the same problem and I want to know if you have any clue on what to do to fix it. My question is: "Do you know how to fix the blurry/noisy shadows coming from your groom by any chance ?"
I'm not sure. But if you look in the hair shader you can disable shadows or reduce the strength of the shadows. It may also be related to the rendering method you are using .... forward shading or lumen or raytrace settings. I would guess if you are seeing something odd it is related to one of those things.
@@DirkTeucher Ok I'll try to change the rendering method. At the moment the only thing I did to get great shadows was to change the strands to cards but, on one side I get great shadows, on the other side I get "not so realistic" hair... The noisy shadows were there with the hair that I created with blender and also from the metahuman hair. Thanks to the metahumans hair I was able to change it from strands to cards.
Thanks for the help I'll try to play with the rendering method a bit ^^
I have a problem with the export. I set up a surface deformer for my hair and it just takes the guides as groom and the rest is getting lost. Is it possible to export it with the surface deformer baked? Or do i miss something?
Apply all modifiers in Blender before export... oherwise test which modifiers and settings port to UE and posta video of your findings ;)
Hi, it looks like the plugin is discontinued.
so sad this addon doesn't export braid nor correctly. I have try to create different braids and export but the addon looks like lost a lot of points along the curve and I got smt noot looks as a braid in UE
Did you find an alternative solution? Like allembic?
Yes! Apply all Nodes. Then go sculpt hair mode. Then go Menu Curves and convert hair to old system. Then go to particles properties and make Render and viewport steps on maximum and diameter root you need. Then export hair into UE5 using addon from video. Use Cycles mode!
@@ksunnywazowski excellent 👍
I got a braid into UE5 but the physics sperate it. do you know how to fix that?
@@btmanimations7079 I keep getting a lot of questions on this video about various hair problems so will have a look this weekend and see if I can do another video to answer these questions.
can I use this add on to sent my rig generated by auto-rig pro to UE5 ?
I don't think it will send over any custom controls. Just the Skeleton and animations ... but you should try it to be sure. A lot of pro animators I have spoken to are using Control rig in Unreal to create rigs as it is very simple to set up an IK rig with custom controls in Unreal now. If you want to be able to create skeleton animations in Unreal instead of Blender then that is what I would do.
UE5 says "could not find bind pose" when i transfer. anyone getting this?
Is this in 5.1, 5.2 or 5.3 ? And what version of Blender? Are you using a skeleton in blender?
@@DirkTeucher its 5.2 UE5, 3.5 blender & newest GitHub pipeline. im using the UE5 skeleton and hair is made with curves. It takes a while to export from blender & when i enter UE5 all i see is the error message and no grooms.
I am using Blender 3.5, Unreal 5.1.1, and Send to Unreal 2.3.1. The grooms are sending, but for the effects of any GN modifier to be transferred as well, I need to apply it! Does this happen to you?
You need to add a realize instances node at the end of your geometry nodes network for it to export correctly.
@@DirkTeucher I tried this a number of ways. I added the Realize Instances node at the end of all the modifiers, and then applied them (tried not applying them as well, but that didn't export their modifications), and the exported groom looked like a very low-res version of what is seen in Blender. Is there anything additional that I'm missing? I just want to have the Geo Node data translate to Unreal, or it doesn't seem like the new hair system is worth it unfortunately.
@@SadPanda449 I can realize instances for geometry and export it perfectly with usd or fbx or gltf. And groom exports using this plugin perfectly for me. No idea why geo nodes are not working with the plugin as I have not tried to combine the two.
You may have to export the objects separately.
And you should log a bug on github if you can reproduce the problem and explain the exact steps you are taking to get it.
Does this grab the material too? Thanks.
It does grab a material but cannot remember if it handles pbr. I use usd or glb files to transfer static meshes for the best material transfers between blender and unreal.
Hi, it doesnt work when im exportinmg it. It says that i have to enable groom but its already is... and i have restarted ue too
Did you enable both groom plugins in UE? And are you using use 5.1 and blender 3.3?
@@DirkTeucher thx for your answer! it works now with 5.1 :) was using 5.0
I get the same , but with correct versions of UE & Blender... Won't export... Any other ideas?
This would make it so nice to export to UE. Unfortunately I am getting the same message. It is saying to enable the groom plugin, but it is enabled. I'm using UE 5.0. I hope this can work. It works for geometry just not groom.
Oddly enough I got it to work by turning the groom plugin off, then re-enabling it.
I know this is a long shot, but I don't suppose you could do me a huge favor and drop me a link to the Blender addon? as in, a direct link to the zip. I can't get the damn thing because Epic/Unreal doesn't recognize that I have linked my github account. So I'm stuck using obscure methods of getting Blender stuff into UE. Many thanks in advance!
No problem (if you have discord). Drop me your discord id. I will delete your comment after also so you don't get spam.
Cant find this plugin?!??!?
You have to register with Epic games and request access. I put a link in the description.
Does it work with Blender 3.5? Thank you
I have not tried it yet in Blender 3.5. But I am 99% sure it will work just fine in UE 5.1 until at least blender 4.0 . The blender upgrades usually do not break plugins on the blender side.
@@DirkTeucher thanks. I’ll try. Just connected with Gothub 🙏🏻
Anyone have any info on how to export hair from blender now using the new hair system 3.5 to ue 5.1? Seems to be different and not working as alembic. Not with this plugin but any manual way or other way to export it would be appreciated
@@naytbreeze Make sure you apply all of the hair modifiers and do not custom create folder path in the Pipeline Exports then 'Push Assets'
@@mixedjungle4928 Its giving me an error for some reason once I add the modifiers and try to push with them. I can push everything else without it but once I apply it gives error/ Not sure if its my hair or what it causing it but it pushes blank groom files if I dont apply modifiers once I do it wont push
Is there a Unity version for this by chance?
If unity supports alembic you should be able to export it that way from blender.

Link is dead, got a got a 404
It is not sending the groom. Do we have to do anything inside Blender in order to make it work?
What version of blender and unreal are you using?
@@DirkTeucher 3.5 😬
@@lucianodaluz5414 and what version of unreal?
@@DirkTeucher 5.1
@@DirkTeucher
Im getting the message, although everything is enable and there is no "Settings for Import groom" in Unreal:
"Please enable missing plugins in Unreal: Groom. Or disable the Groom import setting."
I don't know what I'm doing wrong, I don't get unreal as an option under Pipeline>Export...
Did you find a fix for this? I only have:
Push Assets
Settings Dialog
You need to make sure python remote execution is enabled in the project settings. That might be the problem.
Sorry but how do i can export the hair as just one groom?, so i can attach it to a metahuman :c?
Never tried it. But I would start by trying to export the metahuman head mesh from unreal (which you can do) and do the groom then export back to unreal to see if a straight swap is possible. Otherwise I'm sure blender must have a way to separate the groom from the mesh in the groom settings somewhere.
@@DirkTeucher found a way, convert all the curves in particle system, hide the emiter and export it as an alembic! Thanks s2
@@sebzduran thanks for explaining I was planning on doing it too at some point in the future.
