Daz problem with Iray hair - need help please

[Dash4950]

hello everybody i have probem with hair iray ,if you could explain to me how to regulate her please because her makes me her with all the hair, and I do not understand why ..

sorry for my bad english

Which hair is that? It looks like it's sinking into the head a bit or if you have smoothing on it is separating. I have seen that happen can you post more images in default position with a close up of the head?

oot samira hair ,I put you another screenshot if you know how to fix it thank you

You could instead of fitting it to the head just parent it to the model's head and then use the translation tool to lift it up a bit and possibly widen it using the X parameters slider, but I agree with what Pen said about it sinking into the head. Also even though Gen 8 has clones for previous models doesn't mean that things are going to fit perfectly all the time. I've had some issues with Gen2 clothing fits.

 

[Pendraia]

Have you fitted the hair or is it parented?

Either way, have you added a smoothing modifier?

I'm not sure that I own Samira, so I can't check for myself.

the second screenshot is on gf3, the hair is autofit gf3 and yes I made a smothing modifer ,I think it's a problem of shader but not on because even if I change it does the same

Turn off all the Cutout Opacity in the Surfaces tab and turn off the main strands and look at the skull cap part of the prop to make sure it's not sinking into the figures head. If that's not the issue then there is another solution... April helped me out with with one of her hairs that looked strange after I rendered it... it's another surfaces fix.... I'll see if I can dig it up!

Let's see if this works..... it's a text file and it's got all the info you would need to set up hair in iRAY. I didn't write this, I snatched it from the DAZ Forums a while back.... I know this isn't your native language but perhaps you can run it through translation software...

Other settings to try:

Other settings to try:

base color = texture map + color
diffuse roughness = 0
translucency weight = .1
base color effect = scatter only
translucency color = (what you think the transparent color should be)
glossy layered weight = .63
share glossy inputs = on
glossy color = 1.00 0.95 0.80
Glossy color effect = scatter and transmit
glossy reflectivity = 0.49
glossy roughness .2
glossy anisotropy = 0.97
glossy anisotropy rotations = 0.28
base bump map = 2.6
top coat = 0.97
top coat color (based on translucency color)
top coat color effect = scatter only
top coat roughness = 0.52
top coat layering mode = fresnel
top coat IOR = 2.21
top coat anisotropy = .97
top coat rotations = .25
cutout opacity = 1.15
displacement strength = .5
minimum displacement = -0.3
maximum displacement .3
SubD Displacement Level 2

thank you very much so I try these parameters but not his does not go, separately it is a problem of shader but I do not know why it makes me that

 

[Pendraia]

It looks more to me like it is either a problem with the smoothing or the hair sinking into the head. I've seen that exact issue with hair that moves to far apart with smoothing. It would be good to see it without the opacity on to see what is actually happening.

Hmm you might try going under Actors, Wardrobe, and Props, then, down to the Surfaces (Color) Tab and next, go to the the cutout opacity setting and then try turning off the limits or setting them to like 5,000 and then increasing the opacity setting it's a trick Shiba uses to make thin hair fuller.

 

[Bonnie2001]

I think that hair just has to be sitting too far down on the head.

 

[RAMWolff]

I think it's a volume issue come to think of it. Did you try to increase the cutout opacity to like 150%?

 

[Dash4950]

yes its good now with cutout opacity thank you all
