    ...actually tried one more thing before turning in last night and and letting the render process run while I was asleep.  Adjusted the Base colour to 1.00 - .95 - .95 and glossy colour to 1.00 - .95 - .85, (I left the top coat settings where they were as that doesn't have as much an effect), then remembering that this used Iray shaders, opened the UHT2 Utilities folder and applied the "lighten" setting.  That apparently did the trick as just adjusting the colour parameters alone tended to push the base colour and low lights back to looking more grey as in my early trials. It still retains all the detail and looks like hair rather than just a white mass on her head.

    So now that I know the process, I can do this with other hair content and save them as a material preset.

    OK. My point was that if you set all shader colors to white, you can see if it's the shaders or something else that makes the hair yellow. If it gets pure white you can then experiment with the color settings.

    ...it definitely was the shaders.  As with the adjustments I made above it rendered white in the scene.

    Here is the latest  test (added a little colour/texture to the backdrop so the hair stands out more).

    Yes, that color looks good.

    ...and it works well in different light settings as it picks up only a small amount of colour highlight from other lights.

    For example I was at a pizza joint for lunch with my business partner yesterday and there was this older gent who had pure white hair standing by the pickup counter where a large red and blue neon display was just above.  His hair took on a little of the colour from the lights near the fringe and tips (similar to rim lighting) but for the most part still looked white.

    This is what I was going after.

    I know this is an old discussion, but I just came across it and thought that I would post this image - which I just did quickly - to show how my new product Hair Lustre Shadres for iRay may be able to help with getting a more realistic albino hair. There some even lighter shades included in the product, but I thought this one (Sun Bleached) worked pretty well to get that off-white tone. There are of course many darker tones too. I think the real benefit is that it catches the light much better than standard shaders, particularly on lighter shades such as redheads, blondes and of course a range of very light and pale shades.

    In Poser, I found that I couldn't get shockingly white hair or wings because most light sets hav some kind of tint to the main light. Often it was flesh tone to keep the skin tones from looking washed out. I solved it by applying the trans map to the ambient or reflective channel of the shader.

    ..In Iray 6,500°K - 7,000°K will give a good stark white "studio shoot" light.

    I tested the hair in a scene lighting situation using the Sun/Sky setting and it still came out looking very natural and even had nice translucency (one of the qualities that can be adjusted in Slosh's UHT2).

    Again the trick with albino hair is it is not just bleached white or platinum, but totally lacks any pigmentation and therefore has a higher degree of translucency.  Think of micro thin fibre optics which refract and scatter light rather than absorb it.

    PhilW that looks very good, would love to see it on a character with albino skin.

    I'm not sure that I have such a character "out of the box". Do you have any recommendations for such a skin?

    ...I used SBP3 to create a realistic albino skin as there ts no pigmentation to the epidermis, vascularity has a minor effect on the appearance and SBP has a vascularity overlay.

    Thanks - I don't have SBP3, but after I posted, I thought that I would try and take some cues from the image you posted with your original post. I started with V8 as she has separate eyebrows, added hair, eyebrows and eyelashes, made them all white and then added one of the Hair Lustre Shaders to them all to get the tone that I wanted.  I also made V8's skin paler, using the SSS maps in the Base Color (they are basically paler versions of the base map) and changing the SSS transmission color. This is what I came up with - this is the raw render.

    For the Albino skin Snowflake for Aiko 7 is the best I've seen. The hair looks great. Skin too.
