CC screws (distorts hairs)

Hi all,
I import daz hairs in CC and they look great:

Then I add the hairs to content library, create new figure, add recently saved hairs and I get this:

As you clearly can see hairs are screwed. Is there any way to prevent this?

If you mean the ends of the wisps as they hang down over the shoulders -- this is a weighting issue and you really should be using physics maps on those anyway (assuming you are going to animate her).  Learn about creating those maps and that should solve that problem.

(And if you tell me exactly what Daz hair that is I might be able to help you with the maps).

UPDATE: I carried out small experiment - used polygon reduction on the model before I added it to library. All the same. It seems something terrible happens when CC saves content to library. I never had problem with another type of content, but hairs are definitely screwed. It may not matter if you are creating some average looking stuff, but for photo-realistic game it is unacceptable.

Kelleytoons,
No I mean broken line. Look near right eye. 
By Kelleytoons - 5 Years Ago
No, that's probably just the hair going through the head -- again, weight maps would solve.

Tell me the hair and let me look at it.

Kelleytoons,
I doubt it is weight map problem. The same broken line again, this time back side:

As you can see back is distorted too. Broken lines again. 
I tried to apply wigths, but all the same. By the way, now I checked and all imported daz hairs have broken lines. For example:
https://forum.reallusion.com/uploads/images/ccc316c4-fa6a-473f-92f8-8076.jpg
Even some standard CC hairs have the same damned broken lines inside. May be CC can not properly save strip meshes or whatever it is, it is CC.

Something for you to try...import the hair as an Accessory and save it to your library, then turn the Accessory into Hair with Transfer Skin Weights any time you want to use it. It's worth a try.

UPDATE: Another experiment. Smile This time I opened new document, zeroed all morph sliders and applied daz morph slider... and it works like a charm. I think you were right. 
Any idea how can I make hairs work correctly with other heads?

P.S. One way I already know - weight painting. But is there easier way? One thing that I hate above everything in 3D is painting weights. Smile

How are you importing the hair?  You should be doing it on a BASE Gen figure (just the standard one, with no character applied).

Then the hair will correctly fit any and all characters (with some slight movements/fitting depending on the character).  If you import Daz hair that has been applied to a character with morphs on it it will only look right on that particular character.

I am usually importing it with custom morph. Probably that's the reason.
I will try import it with base gen figure after dinner. Hope it will work.

That is quite *normal* behavior (in any CC version). Hair is trying to conform to a new head shape morphs and gets screwed up in a way.
While there are many ways to deal with it (edit mesh, edit weights, scaling, subdividing, conforming) and probably each particular case depending on a *scale* of damage would require different approach, one would always work fine.
And that is the method offered by Scyra:
Converting to accessory on the base figure which the hair was brought into CC with (selecting a bake option at the prompt).
And then applying it to any other figure, scaling/tweaking transform if necessary and then Transferring Weight as Hair.

UPDATE: I've tried importing hairs with base figures. It helps (thanks Kelleytoons), but some minor problem still exist:

If you compare with image in first message, it seems significantly better, but deffects still exist. Sad If you are going to show this character from 1 m or further away, it will look great, but from 30 cm it does not. 
I think in it's current state it is useless to create hairs content library - better import them when needed, with characters that will wear them. May be Reallusion fixes it in next releases.
Anyway, problem is solved, I know workaround how I can have great looking charater.
Thanks all.
