    Its the "nearly any" part of that that gives me pause. Which ones does it not work for then (because sod's law says it'll be all the ones I have)? Does anyone know?

    Personally I would strongly recommend you purchase the product and have some fun with it... You may find you have new favorites...  I've only used it on a few hair styles but I have to tell you that the results are breathtakingly realistic.. I'm very impressed with this product and I think its a bargain.  Personally I think the product is good enough to merit taking the risk.  Hope you enjoy it too.  I'm loving them.

    Barbult, it looks as if you deleted the attachment so that the in-line image has also vanished. You need to leave the attachment in place if you embed a link into the post so it shows at a decent size.

    I can still see the large images in this thread, Richard. Evidently Slosh could see them. Can you not see them?

    Nope, just a placeholder box.

    Well, that is a mystery to me. I even tried opening this thread in another broswer (Chrome) after you mentioned this, in case it was a browser cache thing. . I had never opened it in Chrome before, The large images still show up for me, even there. Maybe it is a Cloud thing. Well, I'll repload them and keep the little one, just in case. Thanks for the heads up.

    Edit: I have reuploaded them and kept the small one. Can you see them OK now?

    For Richard (and anyone else) I believe there is a setting in your profile that suppresses all images in posts... maybe you have that turned on?

    Here's one more with MEC4D's free 80's hair. On this one I used the Wide texture, because I thought it looked like it had more visible color variation (probably because of the wider spacing of the texture strands?). This one is less "real" looking to me, perhaps because of the mesh, or perhaps because of the fantasy color I chose. It took hours to render, possibly because of translucency on all those gazillion layers of mesh. I'm still having fun with this new toy!

    Artini, Your brunette looks GREAT! I'm going to have to try Spring Hair. I know I have that one. I haven't tried any dark colors yet.

    Thanks, barbult, these UHT shaders are really great and gives a lot of fun to play with.

    Your render of MEC4D hair is looking very good.

    Here's another one. I used the thin texture and didn't mess with any horizontal tiling. I think it looks great.

    Wow! Credit card in hand. Looks terrific.

    Playing around with this and decided to see what would happen if I applied it to a hair that never really worked well for me when I purchased it over a year ago.  I'm happy with the results.  It is almost like getting two products for one.    I think I might just spend the rest of the day seeing what else among my older products that can be "rejuvenated".  Thank you for making this product.

    Thank you, Daikatana.  It makes me feel so happy to see reactions like this... I know that I really like the way UHT came out, but as an artist, you always worry that others might not feel the same.  I appreciate all of the feedback and the renders that everyone is posting.

    Slosh, I'm not getting good results with the displacement setting. Displacement in Iray requires a dense mesh or high subdivision to get good results. Otherwise the displacement is chunky and ugly. High subdivision requires so much memory that it kills DS for me and many others. Can you give some example settings that have worked for you? I'm wondering if a normal map instead would work much better?

    Steven-V has it right... converting to iray for the scalp helps quite a bit.  Fortunately, many hairstyles don't show much of the hairline as the artists have done a good job of hiding it in the layers, but for those that do show the scalp or hairline, it does require a bit of playing to get a good match to the hair.  Starting with the IRAY conversion does help.

    <snip> 

    dhtapp, sometimes (and I stress the word sometimes) using UHT on the scalp produces decent enough match and doesn't look "too bad".  It's worth applying it to the scalp just to see if it's workable, and if not "undo" to get it back to normal.  

     

    Dumb Question Time: Which default shader should I use to perform the scalp conversion? I'm not sure what I'm looking for.

    Thank you, yes - and I'm glad to have seen them.

    In regards to the scalp.  I have found that it is OK to apply the texture to the scalp. 

    However, do not apply any displacement to the scalp, that is where you run into problems.  the scalp needs to be be completely plain and just use all the other goodies on the other parts of the hair.

    There is a setting directly under the displacement map area of the shader that lets you set a subdivision level for displacement... I believe I set the Displacement ON preset to automatically increase that to level 1.  So far, that has been good for me.  I have a pretty good computer, so maybe I didn't notice the memory kill (I apologize for not thinking about less powerful systems).  The displacement is actually pretty subtle when it is used.  It uses the same map as the bump.  I originally tried just increasing the bump strength to get the same effect, but it didn't looks smooth to me, chunky as you described above.  So I went with displacement.  If it seems like more people are having issues with that setting, I will explore different solutions.

    The Iray Uber Shader can be used to convert the scalp to iray shader without changing any of the maps, or you can use the ctrl-click method to apply UHT without changing any of the maps.  Ctrl-click with the scalp selected in the surface tab (and make sure the hairstyle is also selected in the scene tab), then choose Selected and Ignore textures.  If you have a texture already on it that is close to your chosen color, for example dark brown scalp for dark brown UHT textures, then the match is close, yet you can change the color of the Base Color channel to get a closer match.  It's generally better to go a bit darker on the scalp than the actual hair, so it will look a bit like roots on real hair.

    UHT hair shader looks great on older products, like shown below with Aery Soul's Golden Drops hair.

    This is Fred Winkler Art's new model in the DAZ Shop http://www.daz3d.com/fw-derek-hd-for-michael-6 and he certainly is a hunk, wearing Wyatt Hair http://www.daz3d.com/wyatt-hair-for-genesis-2-male-s with the UHT shader Honey Blond TN. 

    What an amazing product this is Slosh, it certainly is giving new life, and realism to hair in Iray. I wish you many sales.

    I have tried this with the REAL Hairy product, which I use quite a lot. http://www.daz3d.com/real-hairy , for some reason the strong colours like Blueberry, Deep Purple, Emerald, etc work very well, but strangely, the browns, and blond colours only partially. With the lighter colours there is still a lot of the base black colour of the prop showing. I have tried several work arounds without success. The products own material colours do not convert well into Iray either. Possibly because this is a fibre mesh product or something similar.

    However, for all my other hair products it works great, and will make a great difference towards getting realism in my Iray renders. Go buy it folks, and see for yourself !  wink

    Cheers.

    I think the thing that's holding me back, as a hairdresser, I'm not seeing allot of variegation of the hair colors.  You know that hair color has sometimes upwards of 10 to 20 shades in a hair strands clump?  I like how some of the darker colors look with the nice gloss but the lighter shades look a bit .... flat to me.... Sorry, from  a professional stand point I'm only pointing out what I see comparitively to what I see on a daily basis in life and work.

    V5 Elite Ponytail and Dream Hair. I hated Dream Hair before UHT transformed it. Today I customized the transparency map by adding some dark vertical lines randomly spaced around to make the hair more strandy. I think that helped.It still has a flat look at the roots, where the 2D mesh strips are easily discerned, but I think the middle and ends are awesome.

    Got it (drained what was left in my PayPal!), installed it, used it, loved it.

    I was able to dig out my almost forgotten runtime of V4 hair and repurpose a number of models that I've always liked, but didn't look good in a modern render. 

    Thanks, Slosh.

    I'm nearly positive that Real Hairy is indeed fibermesh and doesn't have uvs to really benefit from the UHT textures.  Not to mention that the individual hairs of Real Hairy are so tiny.  Did you try using the Backscatter OFF and Top Coat OFF presets?  That might help, but I haven't tried UHT on body hair or eyelashes.

    I was not going to buy these shaders at this time.

    But seeing all these great renders from everyone has definitely moved this item from the wishlist in to the cart.

    Great creation, Slosh!

    I completely understand what you are saying RamWolf... I did use 10 layers to create the hair, each a different hue and brightness, but perhaps I didn't vary them enough?  I was trying to avoid strong streaks of different color that would stand out too much when repeated across several "panels" of the hair products.  I think you can see the most obvious example of the variations in the Peacock presets.  I am thinking of releasing some additional textures with greater variety in the hair and more fantasy shades.   Might do it as a Christmas freebie if I can't get it done before then.

    And no need to apologize for sharing your opinion...  though I would like to point out that nearly every hairstyle you purchase is just a single color that has been hue shifted to provide more choices.  I did not do that with this product, though I think it might look like it based on your observation and somebody earlier as well (Tobor, I think).  Either way, I still hope you are happy with the product.
