"Hairy" problem with Luxus (LuxRender)

Hey Guys,

I bought Luxus yesterday and played a little with some things I'm very amazed with the results. But one thing that won't really is the auto-convertion of the hair. It looks very dry and plane (attached Image). I already looked in the luxus discussion threads but couldn't find an answer. Maybe i've overlooked it but with mor than 100 pages this could possbile happen.

Things I used in the scene:
Genesis 2/V6 with Norma Texture
Deeta Hair
Classic Deco Scene
3 Area Lights

I hope one of the luxus pros can help me out here. Thx in adavance! (and sorry for my worse english :))

Kind regards, Nico

    I would try the "Luxus - LuxRender material" thing, choose Glossy and tick the copy studio parameters and see what you get. From there i would play with roughness U and V.

    For testing purposes, I would reduce the size of the render in half so that it renders MUCH faster

    Things I have copied from the loooong Luxus threads concerning hair ...

    HAIR
    Texture "Kd_texture0" "color" "imagemap"
    "float vscale" [-1]
    "string filename" ["C:/Users/.../Documents/DAZ 3D/Studio/My Library/Runtime/
    Textures/3DUniverse/Genesis/Sadie/3duSadieLongHair_Blonde.jpg"]

    Texture "Kd_texture1" "color" "scale"
    "texture tex1" ["Kd_texture0"]
    "color tex2" [1 1 1]

    MakeNamedMaterial "material0"
    "color Kd" [0.9 0.45 0.05]
    "float thickness" [0.1]
    "float p1" [-2]
    "float p2" [20]
    "float p3" [2]
    "string type" ["velvet"]

    MakeNamedMaterial "material1"
    "texture Kd" ["Kd_texture0"]
    "color Ks" [0.8 0.8 0]
    "float uroughness" [0.3]
    "float vroughness" [0.3]
    "bool multibounce" ["true"]
    "bool separable" ["true"]
    "string type" ["glossy"]

    MakeNamedMaterial "Mixed"
    "string type" ["mix"]
    "string namedmaterial1" ["material0"]
    "string namedmaterial2" ["material1"]
    "float amount" [0.3]

    NamedMaterial "Mixed"

    Ok, I figured it out. To get my hair to look right, I did NOT change it to a Lux material. The solution sounds counter-intuitive to everything we’ve been taught, but it works! I doubled the strengths of my diffuse (after changing to pale gray 192:192:192), my opacity, and my bump. In this hair product, that meant 200% for diffuse and opacity, and 0.60 for bump. Of course, you have to turn off limits in the parameter settings for these sliders.
    See for yourself: this render is with all of the gammas set to 2.2 and the diffuse, opacity, and bump strengths doubled.

    Thanks, i'll try it out, but for the next days/weeks i'm involved in some other projects, so now is no time for this.

    Kind regards, Nico
