Here's a short tutorial on how to simulate hair curves in Blender ! It uses cloth sim and proxy meshes, not simulation nodes. It's not for complete beginners but you'll be able to animate hair without extensive knowledge about geometry nodes or simulation.
You can download the custom nodes shown in the video for free right there : rakenval.gumroad.com/l/xjkze
Constructive criticism is welcome :)

hi rakenval, i use this method for animating the hair. but when render in cycle. the hair always been off or messed up.. is this problem happen for u too? i try evee, and it render like normal only in cycle it became messed up..

@rakenval Ай бұрын

Hey ! Sadly I do not use Cylces so I wouldn't really know, but it's weird though, I don't think the render engine should be affecting the simulation...What do you mean by "messed up" ?

Hi, I have two questions: How did you make the skin texture? It looks really good! Was it texture painting? Can you texture the hair to change its color/make it stylized?

@rakenval 6 ай бұрын

Hi ! Yes, the skin is hand-painted. As for the hair, the color can be changed since it's made with a color ramp. You can even play with the Curve Info node to get strands of different colors. I'm not sure what you mean by making it stylized, but stuff like specular and translucency can also be tweaked to obtain different styles. It's fully procedural (but using textures is possible) ^^

Hello ! It was inspired by the tutorial on Lightning boy studio' channel, if you want to make anime characters you should definitely check their channel out ! You can also get a similar shader in the free demo file I put on gumroad (the blond hair) Glad you like it ^^

Thank you for great tutorial! I tried this but I have a problem. Even if the number of hair curve segment is 8, I converted hair curve to mesh then the number of mesh vertices is huge number (over 80) Do you know how can I solve this?

@rakenval Ай бұрын

Yes, I do not know why this happens, but the fix is to resampke the hair curves to the correct number (in your case it would be 8), by using and applying a Resample Curve node If you convert right after applying the issue shouldnt occur

Is there any way to make the proxy move with an armature? If I move an armature the hair follows, but the proxy stays behind. Is there anyway to constrain the roots of the proxy to their initial location in relation to the mesh? Similar to how the hair system's roots stay with the mesh?

@rakenval 2 ай бұрын

Proxies should be parented to either the character or the scalp mesh That way they should follow along But if you have cloth sim enabled and are moving the character after the sim was baked, it won't follow because the bake overides evrything

Hi - how well does this hair method translate to other programs like Unreal 5?

@rakenval 4 ай бұрын

I'm not sure actually... I know you can export the curves as an alembic file to import it into Unreal, but past that step, its quite hard to get them to look the same as in Blender. The shader and the thickness of the strands is hard to replicate there. Not sure Unreal has hair tool similar to the hair modifiers either That being said I'm not very experienced with Unreal

This tutorial is awesome! But Im trying to apply this to the tail of a character, the fur is squirrel like. I dont need cloth sim, I just want the hair to move well with the tail so I only have a proxy. I have the proxy with a surface deform on it thats connected to the body, but when I move the tail rotationally, the hair moves WAY to much now lol. Ive been trying to find what is causing the issue and I think it has to do with the set position node thats in the follow proxy. Do you happen to know how to fix this? Thanks =)

@travissullarts 8 күн бұрын

I think I may have figured it out. Not sure if its the correct fix. But what I did is, I made all the vertices 100% weight painted on the Root Vertex and rebinded the proxy to the body with no vertex groupings on the surface deform, and decreased the strength. The proxys wont follow exactly with the mesh, especially if you have the strength very low, but it seems to do the job.

@rakenval 7 күн бұрын

That's weird The Set position node is supposed to override previous transformation/defomation affecting the hair curves Is the proxy also affected by an armature modifier, and to which object is it parented to ? I Know having an armature after a surface deform can cause double transformation issues, but apart from this I don't have any other guesses It should be 100% possible for the fur to follow the tail correctly

@travissullarts 7 күн бұрын

@@rakenval So the fix I stated above caused some more issues. But without the fix I currently have just the surface deform target to the body with a strength of 1. The proxy curves seem to follow the tail without any issues. But the children seem to go way out of control. Should I use an armature modifier instead?

@travissullarts 7 күн бұрын

Ok, so I made a few mistakes and also corrected a few problems. Main problem was that the follow proxy wasn't underneath the surface deform. I fixed that, but it caused another issue. The guides would move with the tail, but the children stayed in place. To fix that, I had to disable Surface Rest Position in the Interpolate Hair Curves Modifier. Then after that, add a Surface Deform in the proxys with the default settings, Target the Body and then bind.

Glad you resolved it, well done 👍 The Interpolate Hair modifier can be a bit tricky to work with sometimes

The proxy method doesnn't seem to work with rigged meshes too well

@rakenval Ай бұрын

I suppose it depends on how you're using the proxies I haven't explored using it for fur or stuff like that very much so I suppose you could run into some issue there but for haircuts I don't have any problems with my charas (the scalp mesh isn't deforming so it easier) May I ask what is the issue more precisely ?
