I need to make a Veins HD Morph for Genesis 8 Female.
The current HD vascularity options on DAZ's store are of poor quality, because they don't even have a translucency map for the veins, that means there is no green color for the veins which looks terrible. The vascularity systems currently available have too many god damn veins all over the place.
I need to make my own HD Vein Morph for G8F, but DAZ seems to only let me work with the base resolution in Zbrush, but I need higher subd level in order to make nice rounded veins.
I already made veins using displacement maps which looks fantastic, BUT at certain angles IRAY doesn't render displacement maps properly. The best solution is to make my own HD veins morph. UNLESS one of the PA's steps up and makes a proper vascularity system and doesn't neglect the creation of translucency maps with the green color for the veins, and you can't just spam the body with random veins, you need to follow an actual vein diagram chart of human physiology.

Unfortunately displacement, bump, or noral maps are the only optiond - at least unless soemne takes the SDK and codes their own take on HD morphs.
Not really. Think about the Veins as rigid following (?) clothing ;). You don't have the PA's restrictions to G8 mesh, but you have other troubles (get the skin color right under it :P).
While I have no idea how you could do it yourself, I've often lamented the fact that the Vascularity HD add-on doesn't come with the translucency map as you suggest. Perhaps Zev0 might see this and become inspired.
I think the reason/issue with it is that it would end up overwriting whatever SSS maps are already being used...unless they were able to be properly blended in via LIE.
Good point. I do use vein maps on G8F and I have to put them in place of the existing translucency maps. Pity there's no way of blending two maps in the surfaces panel.
Yeah, that's why I've never been a fan of LIE. I much prefer to blend stuff into skin via PS and most often it looks better in the long run. LIE is pretty much only used for eye makeup...and even then I'll always vote for diffuse overlay.
I find it a little odd that a PA would put all that effort in making HD vascularity morphs and not bother to make any kind of texture maps to go with it that can be edited in Photoshop or something like that to match the base skin with it, nothing fancy. Like some of the other stuff they sell here & other places, its "half-done" where you're required to finish making the complete product.
This doesn't look bad does it?
My issue is that you can see every vein, whereas with most people you would only see one or two...mostly the inner arms, backs of the hands, maybe a couple on the breasts for females. I know at least on me there are some vein bumps you can see, but the vein itself is too deep to be very visible. I'm also pale like a vampire, haha, so my skin is pretty translucent.
Really.
Bump maps affect shaders, but displacement maps affect geometry: they work with subdivision surfaces. Same math, and in IRAY the same engine. Paint some radial gradients on a displacement map and set it to a high enough gain so the figure renders with spikes. The spikes will cast shadows.
The color is straightforward, once you remember that veins carry deoxiginated hemoglobin.
Unfortunately as I learned, Iray has its limitations with rendering displacement maps. That is one reason, why we see so many HD morphs.
For viens, if you want to add colour to them it would be much easier to do with displacement maps rather than HD morphs. Because when you draw the veins for the displacement, then you already have the pattern in the right place to colourize and place on the skin (or the translucency maps..or both..depending on the effect you want)...It is much harder to try to follow morphs and attempt to get them all lined up proper.
Also...for G8F do you really need the veins that large, where it matters for a high displacment?.....not unless she is a majoy body builder would the depth of the veins be that important.
Anybody would have a clue how to do that? Maybe @Singular3D
sounds like the way to go to me.
ever consider developing a product like this, Rawn? you definitely have the skills to do it.
(i almost said 'chops'. but then i remembered who i was speaking to.)

I do that quite often with my characters....there is one pending where it is very obvious (and extreme...and not what the OP intended..LOL)
good lord, rawn.
well, when you go monstrous, you certainly don't mess around. i reckon even a clan of dark elves would think twice about taking that guy on. :)
my runtime would be a really dull place without your characters.
i have a theory that your sleep is haunted by visions of cute fuzzy puppies and perfect summer-day picnics, and you're driven to create dark and savage stuff to compensate for those terrible sunny moments. but i'm probably wrong.
sweet work, regardless. whatever your fountain of monstrous imagination is and whatever it gushes, may it never run dry.
:)
