Problem with Janise hair and grey shader (old woman)

Hi everyone,
I bought this hairstyle (https://www.daz3d.com/dforce-janise-hair-for-genesis-9).
I’d like to turn it into hair for an older woman, so I want it to be grey.
Unfortunately, grey wasn't included with the original product.
Do you know of any reliable hair shader pack that would let me apply a grey color to it?

    My favorite hair shader pack is this one: https://www.daz3d.com/backlight--hair-shaders-for-iray-

    ...I would also recommend one or more of Slosh's hair shader utilities. They also work with Strand Based hair.

    All are on sale and Colorwerks Extreme in the Outlet store.

    Also open the hair in the surfaces tab as some hair content has multiple metarial zones for colour depth..

    It's not a helpful answer to your question, but of late, I've primarily been adapting "graying" options from other Omni hairs.

    Have you tried Blonde Platinum or Silver (which often look greyish), perhaps modifying their shaders a bit?

    There is also a ($1.99) add-on btw, though it doesn't seem to have any Grey either:

    Since this hair is dForce, I'm guessing it is probably strand based. I would use the OmniHair chader if that's the case. It will help with render loads if the tessellation is set to zero. There are shader presets that are made for it.

    Janise is Omni out of the box. This is Janise with an Omnihair Naturals brown and graying done manually, using a combination of strategies used in a couple of other Omni hair products that offer graying options.

    My OmniHair Naturals product has a silver preset and a grey preset depending how dark you want to go: https://www.daz3d.com/omnihair-naturals

  • kyoto kidkyoto kid Posts: 41,847

    ...looked at both products and neither mentions Omni shaders so wouldn't standard Iray shaders still work?.

    I have the hair and it is strand-based hairs, using Omni shaders. Are regular Iray transmapped shaders able to be used on these hairs?

  • memcneil70memcneil70 Posts: 5,289

    As far as grey hair goes, regardless of type, I would love a more natural looking greying shader that allows for streaks/hairs of greying/white hair scattered throughout a person's natural color. We don't wake up one day with our head all of a sudden white or grey. Well only Anderson Cooper did that, or someone who has lost their hair due to illness and it comes back in.

    Thank you so much for your reply.

    I actually do have your shader pack, and when I select the hair in the scene, it doesn’t work, I even tried through the surfaces tab.

    Oh no I'm sorry to hear that! As shaders the surfaces do need to be selected which it sounds like you did - could you perhaps post a screenshot or two so we can figure out what's happening?

  • jeremie.devjeremie.dev Posts: 37

    Here’s a screenshot.

    I also forgot to mention, I don’t know if it matters, but I’m working on the Alpha version.

    I can't see your scene tab in the screenshot but is the hair selected there as well as the surfaces? I've used my omnihair shaders in the 2025 alpha version so that's not an issue - the scene selection thing is usually an issue for material presets rather than shaders but it's something to check at least

    Yes, the hair is also selected in the Scene tab.

  • Silas3DSilas3D Posts: 733

    So what happens when you try and apply one of my colour presets? Is there a particular one you're trying?

  • jeremie.devjeremie.dev Posts: 37

    Nothing happens! I select a color, I click on it, but it's like nothing is applied. Nothing loads. I tried with several colors, but nothing works.

  • Silas3DSilas3D Posts: 733

    Ah I think I know what the problem is. In your scene tab you've got the scalp selected, not the hair - if you expand the scalp figure in your scene tab, there should be one or more parented hair figures with a similar name. You need to select those when applying shaders, as the scalp is usually either invisible or just provides a flat colour with an opacity map so that scalp skin isn't visible.

  • Silas3DSilas3D Posts: 733

    With traditional card/ribbon based hair that uses opacity maps to fake strands, everything is usually in one hair figure, but with strand-based hair the hair is usually grown out of a cap, often labelled as scalp as with this hair.

  • jeremie.devjeremie.dev Posts: 37

    Aaaah! I’m really sorry for my question then. Usually, it’s in two parts with the scalp inside the hair figure, but this time it’s the opposite.
    In any case, thank you so much for your replies!

  • Silas3DSilas3D Posts: 733

    No problem :)

    ...I've used Slosh's Iray hair shaders on strand based hair and they work fine.

    Thank you for that information. You just expanded my options.
