    The translucency setting in the hair material seems to be the key, but you need to either crank it really high, or have a really bright light behind to make it work.

    Still experimenting...

    Ok, Translucency in the hair material is what makes this work. I have it set on a gradient based on the incidence angle, with it ramping up to 100% close to the 90 degree mark. Where the sweet spot is for the transition is hard to pin down.

    Also, I've only gotten it to work with an area light as the light as my back light. Point and Spot lights didn't work. (Direct Lighting only, Radiosity + FiberFX = Render times into the NEXT millenia...)

    Your backlight must have raytraced shadows on. Things wash out, otherwise.

    Is that Lw or houdini? and if LW..who did it? Maurocor usually do nice soft hair ends, seems it should be straightforward to follow his tips with fiberV for the fiberscale, and add some transparency in the tip transparency

    Edit Lw obviously, since it was from the release showcase, if only I Could stand the long rendertimes though, and especially the VPR..which is where you can see how it is shaping up that is taking too long time, I rather prefer a faster VPR vs a little longer rendertime in final, you just got to have a system that gives you feedback in decent times..In particular for things like this, VPR and fiberfx doesnīt.

    the render is based on the LW2019 content folder > Furry.lws
    it isn't "there" but the example looks somewhat similar.

    yes, render time is... Zzz....

    having tweaked that scene it looks something like this, and took 34 minutes to render on my (old) machine
    (result, after PhotoShop Denoise and Blur)



    (scene file attached)

    it isn't too bad i guess, but certainly not quite "there" either.

    I have mine set ay 80% translucency, no gradient (though i might give that a shot)..and I'm using spot lights with full gi and am getting a decent render time..12 minutes for the back veiw..4 for the front. And I have around 50k fibers on that one.

    yes, but for a professional render you need much higher AntiAliasing.

    for a still image, you'd need at least 20min+20max AntiAliasing.

    20 million? not sure about that...not sure i have 20 million hairs on my head...lol.

    The antialiasing is always something that more is needed...would be nice if we could allow different objects to have different sampling.

    no  

    20min+20max AntiAliasing

    yes, different objects to have different sampling would be great. Asked for it way back.
