Maya animation Alembic Cache to Unreal. Posts Latest Activity. Page of 1. Filtered by:. Previous template Next. Hi all, I am a new user to unreal so pardon me for amateur questions here. I am trying to bring an animated VR project that I did in maya over to Unreal. So I would suppose starting with a VR template will be the right choice? A few questions in my time with testing system: 1 Am I able to bring an animated Character with hair sim through alembic cache over to Unreal?
I've tried so but to no avail. After i import the assets, I have to drag it in to my unreal viewport and it just means I have to re-position them. Tags: None. I think that you have to split your maya character in 3 different animations: hair-body-cloth.

Attached Files. There is some tutorials about importing rigged characters into UE. Are you using the animation baking options when you export FBX? It can help when you have some rigging options that don't convert over.Kirin ga kuru episodes

So I'm glad someone from the community stepped up to show it off. It looks pretty good sim-wise. What kind of framerates were you getting during playback? Comment Post Cancel. Hi scrc0 :- I got about fps with Here are my Niagara settings see picture best Blond long UE4 Groom Hair :. I use iClone too BTW only 6 though. Last edited by Wendyluvscatz ;AM. Thx for your infoWendy :- Yesthe Groom Hair is new and experimental but I guess it has huge potential.
It looks so much better and the Niagara Particle Physics is so much better.
Doesn't blender export Alembic Hair Strands? Originally posted by Wendyluvscatz View Post. Originally posted by NilsonLima View Post.More results. I've managed to get HairWorks working inside of UE4 with a simple, skinned cube with one joint and 8 guide curves. For the next step, I wanted to create an Alembic Cache of the animated cube, and apply the hair to the cache inside of the Unreal Engine. I was able to import the Alembic Cache using the Alembic Importer as a Skeletal mesh, and I see the cube playing the animation.
I created an Actor blueprint, stuck in the Skeletal mesh, and attached a HairWorks component along with the correct. However, the fur doesn't follow the animated cube. The fur remains in its original position. Is there a way to get Alembic Caches to cooperate with HairWorks?
This would be ideal for us because our rigs are fairly complex, and using caches to bring in our animations simplifies the process quite a bit. We'd like to get hair on the character and also have it follow the geometry accordingly. Attachments: Up to 5 attachments including images can be used with a maximum of 5. Answers to this question.

Hair not following. Hello, I've managed to get HairWorks working inside of UE4 with a simple, skinned cube with one joint and 8 guide curves.
Are there any steps we can take to get HairWorks to work with Alembic Caches?The Hair Rendering and Simulation features are intended to provide a minimally viable implementation of strand-based hair importing, rendering, and simulation.
This update does not provide a hair grooming solution. Other tools like OrnatrixYetior Houdini can be used as well. This document outlines an informal schema for Alembic files in an attempt to standardize the import of hair groom and guide hair information into Unreal Engine 4 UE4 for use with the Hair Rendering and Simulation features.
Best solution for realistic hair in Unity?
The intent is that as you generate Hair Grooms, conforming to this schema will allow UE4 to import those grooms directly. Upon import, attributes that are supported by UE4 for both rendering and physics will be mapped to those attributes in the Alembic file. Define a groom-specific, informal, Alembic metadata schema to facilitate importing of hair into Unreal Engine.Pipenv stuck on locking
Examine the attributes that are supported by UE4 for hair, and map those attributes onto Alembic. Properties in this document have an assigned scope. The scope controls at which level the groom property can be defined. This section outlines properties that apply to the groom as a whole. The name and version of the tool that generated this file.

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime. Learn to use this Beta feature, but use caution when shipping with it.
Features available in Beta state give you the opportunity to learn how they work, plan your pipeline, and create test content. You should use caution when using these features in productionas we are still working to get to shipping-quality performance, stability, and platform support. We support backward compatibility for assets, and the APIs for these features are stable.

Hair substance for generating hair textures for Unreal Engine's hair shader model and for use with Hair Cards many small hair meshes joined together and laid all over the scalp. These textures can probably also be used for any game engine. Then you make a material instance in UE4, open the instance and change the textures in there to the ones from this Substance. Then you apply the material instance to your hair cards. A hair card is typically a rectangular mesh with about 20 vertices. You UV unwrap it then you place multiple hair cards all over your scalp, probably about will be enough, bending them slightly or greatly depending on the hair style.
Then you merge all hair cards into a single object and export it as FBX. Then apply the material instance to the mesh. Then pat yourself on the back. Toggle navigation.

As you may know, if you've followed my last series of articlesI've been taking a deeper look at Unreal Engine 4.
In one of the articles, I discuss a little bit about UE4's new hair rendering capabilities, and I presented a very quick example. This time I am going through the process of actually making a nice-looking hairdo in Unreal Engine 4. UE4 doesn't include hair-creation tools.
This means you have to create your hair in an external application, and then import the hair into the engine for shading and rendering. As you can guess, I decided to use Maya to make the hair you can also use Blender, Cinema 4D, and a couple more. Basically, what you need from your 3D application is the capability of creating XGen grooms that can be exported as Alembic files.
In Maya, you have two ways to create the grooms. I haven't tested this method much, but I might do it in the future. The second method is to use curves to create your hair. Basically, you start by drawing a bunch of curves you want to use to shape your hair, and then use those to create the actual hair strands.
In my case, I decided to make a braided hair, so I created the curves that would follow this shape.
One thing you have to keep in mind is that your head scalp should have UVs, because XGen uses the UVs to create the strands. After the curves have been created, you can create your groom.
Hair Rendering and Simulation
You should use these settings to create it, so you can use the curves to shape the hair. If nothing shows up, don't worry. The next thing you have to do is open the XGen pane or switch to the XGen workspacego to the Utilities tab and then create the guides from the curves you created.
Hair should show up now. Chances are you might get hair everywhere, so you can also use a texture mask to control where the hair is created you manually paint the mask using Maya's paint tools.
You can also configure the density of the hair to make it denser, and increase the CV count of the hair so they follow the guides more closely. One thing I did, to make my work easier, was to create more than one description: I created one for the head cap, another one for the braid, and a last one for the tiny hairs hanging from the forehead and sides of the head.Uipath reusable workflow
The reason I did this is because the generated hairs will interpolate their shape based on the guides, and I wanted the different parts to follow the shape I had defined without any kind of weird transition between them. This will not create any issues when you import it into Unreal Engine, if you keep all the descriptions as part of the same collection see the XGen creation window above.UE4 Hair Grooms.Trinity Mysterious System, Unreal Engine 4.25, Hair, Alembic Groom, BETA test

Seeing a few people have posted some amazing work they've produced with the hair system has really inspired me to keep trying - but to no avail so far! The work I've seen has come from people using software such as Maya and I've been using Blender. I made a couple of basic hair grooms following some tutorials out there, exported them to the alembic format, looked at what was being exported as what etc.
Unfortunately I only seem to get the file in UE4 as an invisible static mesh. It shows that there are many, many vertices to it, but they're not visible and it's a mesh rather than groom. If anyone has some suggestions on getting it so that UE4 will accept it as an alembic file I'd be massively appreciative and would happily write up my workflow if it will be of use to anyone, including one of my simple grooms - both Blender file and exported.
Cheers, Chris. Tags: None. Can you share the alembic file? ArtStation - Portfolio. Comment Post Cancel. I didn't centre the scalp when I produced it. Also I've just found that the scaling didn't stay with the scalp from it's original file - so if I scale the static mesh that does import it will show the scalp in UE4.
Just not the hair - so that could well be my issue? Boruki Hey. Unfortunately the curves from Blender come in wrong. Not sure if it's the way Blender exports curves or UE4 that causes the issue.

Will investigate further if I find the time. See my export steps below:. That's amazing. I'll give it a go.Mazda cx 7 vibration
