Thank you for the video! I met some difficulties when approaching this. After I import the animated guides into groom scene, and set up everything, the hair doesn't follow perfectly like demo. It follows a few frames and then went chaos.
Sorry I'm unable to intentify the issue from that description. What I can say about troubleshooting is that you need to identify what is causing the issue. Once you intentify the cause, usually the solution is apparent. Everything on software is cause and effect. That process of troubleshooting is a big part of a TD's job.
Amazing! I have a question, in case we have multiple descriptions, like 10 or 20, do we need to cache the animated curves of each description and do the whole process?
@@wenchannaindeed. For that reason, I generally try to minimize the number of descriptions in my workflow. Otherwise thinks become hard to manage, like this.
@@derekfloodVFX Unfortunately, with the kind of character I usually work with, I think i need to looking for another groom tool for animation. :( What do you think about Ornatrix, geti or houdini?
When it comes time to batch render the animation will the hair cause any issue? Is there any extra steps to ensure it renders properly using arnold renderer?
The potential issues with rendering are not with caches but with modifiers that use random generated data such as clump or noise. It’s good to bake these.
@@queengabby9707 Well, you need to keep the modifiers used for the dynanmic sim, and bake the others that use random values, such as noise that are used for the groom. So with that in mind you could break up the process conceptually into grooming, bake that, and then do the animation/rig setup.
what were the main settings you used on the nucleus and the hairsystem for the dynamic hair simulation to get the hair to keep the main shape but not be stiff? Thank you for the video!
Thanks! I have another question, i have a groom on an animated character with dynamic simulation but i want to transfer the groom on the same character but on another file in another starting position, how should i do this best because I dont really understand it in the video.

Hello Drek I am working in an animation studio in Türkiye. I am responsible for the simulation of hair and clothes for the characters.

Amazing tutorial thenk you very much! Is it possible to export the xgen simulation animation into say unreal? Not for a real time game, but for an amimated video.
Since it’s essentially a part of the rig set up, I would generally say it would be better to do it before. If you are doing the key frame method as opposed to the dynamic method, then you certainly would need to do it before.
Hello, thanks for the tutorial. I made my hair on my character using guides (I didn't use interactive groom). would this method in this video work for my setup?
Thank you for your video! I have a question, so when I import abc cache to curveToSpline, it has enormous size for the curves, do you know why? Thank you😊
@@nataliamatsiuta1848 sounds like there is some scaling on the xGen that the curves are being added to, which those curves are inheriting. Could possibly be the geo the xGen is generated from. I'd suggest doing a simplified test to troubleshoot the workflow.
Hey Derek, what if I already have an alembic groom that was made in Xgen? Is there a way to go about importing that alembic groom onto an animation in maya, simulating it, and then re-exporting it as a cache?
I'd think you'd want to use the Alembic curves as guides for Xgen groom and then go from there. Assuming of course you don't have the xGen the Alembic was created from.
@@acryxia The guide modifier in Xgen has a section where you can import curves. You would import the Alembic curves into Maya, and then use them as guides there.
Blender does not know what xGen is, so you would need to export something that is software agnostic, like the hair curves. You could do this in Alembic and get the curves with animation.
Typically facial hair is short and so would not need to be animated beyond simply moving with the face geometry. Xgen follows the deformation of the geometry automatically
This is amazing video and tutorial but, what’s the perversion for a team at Autodesk to come with a tool, making the user to bake export import turn components on off, parent unparent…I can’t be proud of what they are delivering as application.
@@bmd_videos hair systems are done by generating rendered curves for each hair. That's what XGen does. Geometry is only used as a proxy object. If you want to bring in curves generated in another software you would need to save them in a software-agnostic format like Alembic. If you are new to Maya I'd suggest avoiding that as it is quite advanced.
Me: I don't suppose there's a simpler & more direct, intuitive, user-friendly way to do all this? Autodesk: BWAHAHAHA hello, have we met? ... Honestly, this is insane, there's no way in hell to keep all this straight or intuitive in a production workflow.

Thanks you so much!!
hi, very good video. but can you explain why we need to convert the cached into the fbx? thanks
@@3d.bubble because Alembic requires an external file. When FBX is imported it becomes part of the Maya scene
@derekfloodVFX tbh im not really ubderstand, so what will happened if I dont convert the alembic into fbx?
@ the Maya file will be dependent on external files, which is sub optimal for an asset in production.

Hello Drek
I am working in an animation studio in Türkiye.
I am responsible for the simulation of hair and clothes for the characters.
I have recently encountered a strange problem in some project shots and I want to consult with you in this regard.
I have a cartoon rabbit character in the scene that the animators have finished animating.
I have taken an alembic cache from the rabbit animated model.
I have a copy of the rabbit body without rig , on which I had already made the hair with Xgen and then transferred it to Xgen interactive.
Now, I assinde wrap deformer from alembic cache to the original model.
So far everything works well and with the movement of the alembic model, the orginalmesh also move well.
But
In some frames, the hair is separated from the model and it seems that the hair has exploded and the roots of the hair are separated from the body.
Can you suggest a solution for this?
The wrap deformer in the video is only intended for hand key-framing. I would not use it for a simulation.
How can I solve this problem?
I have put the video link below

Amazing tutorial thenk you very much!
Is it possible to export the xgen simulation animation into say unreal?
Not for a real time game, but for an amimated video.
Yes, I believe it is, but I have not yet tried. A good place to start is with the Meerkat example from the UE Marketplace.
For real hair simulation what is best configuration for computer
Mostly just a decent GPU
I'm not sure to understand why you export your guides as ABC then FBX !? is it to clean somehow the curves ?
Yes, exactly.
Good morning.
Is it better to do a complete animation of a character before doing this hair process?
Thanks
Since it’s essentially a part of the rig set up, I would generally say it would be better to do it before. If you are doing the key frame method as opposed to the dynamic method, then you certainly would need to do it before.

You can convert it to interactive xGen first
@@derekfloodVFX I will try that, thank you!

what happens when you import in those curves with cache>Alembic cache>import Alembic?
@@derekfloodVFX in this case they appear like curves, normal size..

Blender does not know what xGen is, so you would need to export something that is software agnostic, like the hair curves. You could do this in Alembic and get the curves with animation.
@@derekfloodVFXYeah I was doing some research about but thanks anyway
does this work with characters that have facial hair and you want the hair to move along with animated expressions?
Typically facial hair is short and so would not need to be animated beyond simply moving with the face geometry. Xgen follows the deformation of the geometry automatically

I hear you. But what is cool about Maya is that it allows you to engineer tools and workflows to do things that were not otherwise possible.
How can we do it from Xgen?
Sorry I don’t understand your question
Any hair or just maya model hair
The answer is in the title "Animating Hair with Maya XGen"
I mean for example i import character from iclone, am new to animation with maya
