Absolutely Stellar Product!! IDG IRay Hair Essential Shaders
in The Commons
Just about jumped out of my chair to order this one. So many great hair products don't have IRay shaders - and just look bad with only the iRay Uber shader applied to them because the specular maps were painted and manipulated specifically for 3Delight. This is the first one click product I've seen that fixes that.
I tested it on my favorite 3Delight only hair, Fashion Hair for G2. NOTE! You need to hold down shift while applying the shader via the surfaces pane in order to preserve the transmaps!
Here's a sample 10 click render I did with it. Looks SO MUCH better than before.

Here's another Hair shader you might like when you want to do a little more with the hair

Disclaimer: I own and LOVE both products (the artists too, as far as that goes).
It does look better. The hair is excessively neat but it still looks real. It's beats those excessively messy hair models by a mile for realism.
I have both IG Essential Hair Shaders and UHT. I love both. Each are great in their own ways. I would they say are absolutely essential for great Iray hair. :)
edit: added word for clarity.
There are several hair shaders on the market now. The first to appear were the OOT IrayPair Hair Shaders, if I remember correctly. You can always use the Iray shader/materials that come with any hair product, too.
I'll note that the Iray shaders for Sapphire hair are so well-made that I've occasionally copied it onto other hair.
I use OOT's IrayPair Hair shaders and am very happy with those (not here - at the other place) ;).

Straight to my favorites list for next time it's on sale. Thanks!
Aww, thanks Tring! If you started from an Iray material preset, you shouldn't have to hold down the shift key to preserve the transparency maps. The shader presets were recorded to not touch the cutout opacity. If you are applying the shaders over a 3Delight material, then yeah, the transparency map would go away.
The idea of universal hair shader presets is quite old actually. My 3Delight Toon Style hair shaders (with the newer Iray update) is getting close to 5 years old, and I think Bea had some at RDNA even before that. There may even be others I don't know about. The fun part is to mix it up between products, one hair strand from this product, one hair strand from that one. More choices is always good.
I usually use the ones that comes with the product, I assume it's better to use something that's specifically designed for the hair than a generic product. So I mainly use the generic Iray products for 3DL or Poser only hairs.
Guess I'm still a bit of a nube in this area. Had no idea hair shaders were interchangeable. Live and learn. Thanks!
They can be but not always. The assumption made in these products is that the UV map for the hair is laid out vertically i.e. hair texture is all painted up/down, not side/side. For many / most hairs, this works. For some of my personal favorites (those by, for example, Ali / Mankahoo) the UV maps are not laid out that way, in particular the caps. In these situations, the generic shader presets don't really work. It does still depend on the hair. But most if not all of the hairs sold here on DAZ site seem to work with these shader presets. I have the three main ones available (OOT Iray Hair Pair, IDG Iray Hair Essentials, and Slosh's UHT2). They are all excellent in their own unique ways and whichever one you buy will be immensely useful in my opinion.
