UE4 - Hair Color with Blender - Unreal Engine Groom Color 4.26

[@deanstolpmann3797]

You are a lifesaver!! After 60 hours of sweat and tears, I found your tutorial and fixed my issues in 20 mins, Thank you!!

[@Shinjitsu_84]

Many thanks really saved the day for me in Maya even. Process is the same just have to make the tetraheadron on your own and flip the mesh to make the unreal hair UVs direction. Also set U and V to 1 no rotation. Worked like a charm!

[@MarvelMaster]

Nice

[@douglascoelli]

thank you very much, I would love to see more videos like these.

Thank you for this wonderful tutorial 😁

Hi i did this tutorial on my character in UE 4.27 and it worked perfectly.. recently i updated my project to UE 5.3 and the UV doesnt seems to work anymore.. does anybody can confirm if this method works on UE 5.3 as well? Or do i have to find an other solution ?

[@MarvelMaster]

hm there surely has been changed a lot since that

[@PHATTrocadopelus]

Amazing!! Thank You!!

I too would love to hear more about the full buddy hair method that you mentioned.

For those who have issues with unwrapping the Octahedron's UVs, try to Mark Seam and unwrap around other vertices. As of 2.92 Blender I had to unwrap from front side (not back side). For 3.6 Blender it doesn't seem to work at all and after unwrap it always separates one face from the others. So I just had to export from older Blender version. For those who don't know how to add object from other .blend file to yours: On top left select "File" -> "Append", then find .blend file of the scene with that object and select which collection you wish to add it to. You must be in Layout tab though to be able to append file.

thank you！

[@lucascavallari8489]

Is there a way to do it without this geometric figure? I'm doing it for an animal, so I want to do it just with its mesh.

[@bastiensburg]

Hi, I have a problem with baking the paint to texture step. After bake, my octahedron is all black. Only difference is I'm not painting on mesh but using texture in texture paint editor. Do you have any idea why it's not working? Thank you for all your videos btw, really appreciate it.

[@MarvelMaster]

Did you notice the section with the bug? And did you use the right order and checkboxes?

[@bastiensburg]

@@MarvelMaster Hi, the problem was I unchecked "show emitter" option in render tab of hair particle setting. Now everything works. Thank you again for this video really cool stuff.

[@kateryna3460]

@@bastiensburg Oh I had the same problem, thank you for sharing

[@chrisuk139]

Hi, thanks a lot for the create tutorial, it's helped greatly. I was wondering how to determine what the UV settings in the material would need to be if the octohedron had the seams at the bottom, instead of at the back like in your tutorial. The tutorial setup gives compressed UV space for the front of the groom area, so I'm trying to move that compressed part to the underside. Cheers.

[@MarvelMaster]

Maybe change the rotation?

[@chrisuk139]

@@MarvelMaster I've messed about trying different settings for U, V and rotation but no luck I'm afraid.

thank u! this is very usefull. Very sad it seems to b the only tut on this subject here :( how would you go about doing this with maps imported from somewhere else? I made my maps in substance... so I cant really transfer the texture from one to the other. Any suggestions?

[@MarvelMaster]

yes there is a new blender addon that can export root uvs and groups you can find it on gumroad, will do a tutorial once i have time

[@Tenchinu]

@@MarvelMaster amazing! thnk u very much. Cannot wait for that tut... cause this would help with maps so much!!! export roots uvs. Desperately need to find that!! very sorry if it sounds pushy, but drop a link if you know the name :)

[@360ambiencevideos]

did you ever create a follow up video showing how to create a map for a character with legs and a tail ? I am creating a series of animals with fur and Id love a few pointers

[@MarvelMaster]

No but I know that somebody made some bears with the checkermap www.artstation.com/artwork/Xn99KL

@@MarvelMaster you said this wont work on a figure with tail and legs, but what if the tail, body and head were each treated as its own mesh ?

[@MarvelMaster]

@@360ambiencevideos yes sepwrate parts might work

[@mrksdsgn]

I tried the same setup with the texture alignment - but it doesn't seem to work properly. I am able to rotate/change the UV position but it does not look like the exact position in Blender.

I am trying to create alembic strand hair for a Daz character. I exported the hair as an object file from Daz and imported into 3ds max to use the ornatrix plugin to create hair strands from the mesh. But when I import it into UE4 it doesn't have any of the original material/texture. Is it possible to use the original material/texture of the hair mesh with the alembic hair I created from it?

[@MarvelMaster]

The ue4 docs have some info about using hair color from ornatrix i think

[@ykach3]

Hello, I really need your help- I'm doing exactly as you did in this video and sometimes it works and other times it won't (I'm referring to the import part, and when its not working i mean ue4 crushes right after I click on import, I'm using ue4.26, blender 3.91 with rtx3080, Ryzen 3900x ). I think the issues accruing whenever I'm trying to import alembic of particle with vertex groups assigned in density, any idea how to fix it?

[@MarvelMaster]

Import tends to crash when hair is too short

Try it step by step with animal model and got problem on root uv in the unreal looks like the uv is just not right.Wonder if anybody have the same issue and know how to solve that.Thank you

[@caleb1031]

Why do you have to flip, and rotate the hair texture in the ue4 material? That seems like something that could be done in the baking process, or in photoshop at the very least.

[@MarvelMaster]

Well that's true and I was thinking about removing this part But Its necessary when you use a checker map, only with these settings the checker map gets. Displayed somewhat right.

[@BlenderEffect]

@@MarvelMasterUnfortunately I stuck at this part. I tried everything but even flipping in psd or with your setup Im not able to bring the root uv ( the uv map from blender) in the correct position. Any advice on this would be great!

[@MarvelMaster]

@@BlenderEffect hm only advice i can give use the exact same roations of the octahe as i do look. At your axis

@@MarvelMaster No my fault. I watched the video until the end now😬 So I have a more complex character a cat, so It will not worl easy like you mentioned alresdy in the video. Thx a lot.

How would you do this if you wanted to project an image onto something like a carpet to make it look like a patterned carpet?

[@MarvelMaster]

I think I talk about the checker texture at some point or place the plane on the equator of the octahedron

[@TheFrozenFlame05]

@@MarvelMaster thank you! I’ll try it out.

[@TheIcemanModdeler]

I wonder how would the texturing of the hair be done using Maya. In Xgen it uses the scalp texture to color the hair, not sure if the same applies to Unreal.

[@MarvelMaster]

Isnt there documentation for this?

[@TheIcemanModdeler]

Marvel Master There is very little documentation on hair shading been researching from different places and using but and pieces to shade my hair.

[@MarvelMaster]

@@TheIcemanModdeler hm the documentation seems complex... However the workflow is very different because maya can export groom values which blender cant. docs.unrealengine.com/4.26/en-US/WorkingWithContent/Hair/XgenGuidelines/
