Spline Wrap Hair

[MaverickMongoose]

Hi Dr Sassi, hope you're well.

I'm make a piece of thread travel along a path like 4 seconds into this animation: https://www.youtube.com/shorts/L4B6Agk_NbA?t=5&feature=share

I was able to curl some hair around a helix, then using a line I also have hair running lengthways through the thread where it frays a little at the end - so basically I have 2 hair sets.

I then tried spline wrapping both together and along another helix - but no matter what I try it just wont wrap correctly.

The curled hair seems to wrap ok but when I add offset along the helix its a bit funy.

But the line wont wrap at all, it just keeps freaking out.

Is this a limitation of hair or is there a better way to do this to keep the curled and frayed parts but have the whole thread travel along a path?

Here's my file so far: https://we.tl/t-iCYOf4sBql

Have a great new years if I dont hear from you before!

Hi MaverickMongoose,

Thanks for the file and the reference.

I have basically used only two Twist Deformers per Hair-Element (Rendered as hair via RS Render Tag).

One Twist Deformer is Axial to spiral the hair, the other one is moved away from the main axis and creates the Helix. The Cloner is moving the hair through the Deformer.

The Random Effectors below each spline are set to Deform>Point.

The lower cloner creates the most Hair, while the spline below the Main Cloner is for the little "stray hair.

Yes, that needs some fine-tuning (Light and Material, etc.), but I wanted to get your input if that works for you.

The Splines have a lot of points, so they will follow different Twist settings.

Same here, if you are off, have a great start to 2026.

Cheers!

P.S.: Here is a little bit "polished" version.

MaverickMongoose,

I wanted to share as well a version where the Hair grows along.
To have the end differently, I used a Target Effector, set to Repel and Deform> Points, while it moves with the Spline it sits on (Align To Spline)
