Old Man ZBrush Sculpt

Critique Comments please!

Really nice sculpt you got here... Proportion wise, I would think that there is a little too much space in between the eyes, they are wide appart, but mabee it does match a reference. For the sculpt itself, really nice.. I guess your next step is to give it a Vray SSS2 pass...

[MoonDoggie]

Thanks for the comment. I'll look more closely at that area and see if it's close to correct. When you've been staring at things so long it's really hard to tell if they're right. Mainly I'm worried about proportion and to a lesser extend form and flow. Any comments on form (structural, anatomical) things that I missed? That zygomatic bone is hard to find underneath the skin.

The next step is texturing and cutting the symmetry.

This is really good - how will you go about texturing it? Do you texture it directly in zbrush, or export it unwrapped to then texture in photoshop?

[MoonDoggie]

Usually I use zbrush and zapplink to photoreference textures for it. This time, I'm trying a polypaint in zbrush and hand painting the texture. I bought Scott Spencer's book on ZBrush characters and it's got a section that explicitly goes through hand-painted textures. I'll share with you all the maps and textures when I'm done. I really need to spend a good portion of time nailing the sss2 shader though and that is looking like it's going to take a day or 2.

If you want more information on the painting of the texture map I can go over that as well when it's closer to done.

Great model!

Just one tiny thing ocurred to me. You paid so much attention to all the details but the eye balls stand out a bit. I think they could be a bit smoother and also wouldn't you see the shape of the iris slightly stand out?

Can't wait to see it textured!

[judderman]

Looking forward to that. Haven't used z-brush myself, only used mudbox - really liked it actually. This will look great when it's done though no doubt!

Thanks Stefanie for the kind words. The eyeball protrustion is actually the outter membrane of the eyeball. The actual iris is completely flat. Here is the beginning texturing stagesand corresponding renders from it.

Comments critiques welcome. I'm not stopping until it looks like a photograph. Please help me disect the areas of the image that need work so I can refine them to achieve a photorealistic result.

The SSS2 shader is getting there, but still needs some fine tuning.

Eyes need work too, but I'm not sure if it's just the lighting on them (have reflection seen in the eyes) or if it's actually the eye texture/geometry that doesn't look right.

Lighting setup: 2 lights, no GI.

Nice start there!


There's too much scattering happening. Wich gives it a waxy look (esp. in the lips for example. And given the "age" and amount of wrinkles the skin is way too smooth. Here's a neat example:

(Yes i know...i am measured by this example too atm :P )

Check the thread on ZBrush tho for some more renders and some behind info: http://www.zbrushcentral.com/showthr...2&page=1&pp=15
(linked to page 15 for the greyshade renders as they show a lot of skin detail. Notice that even tho the "guy" is a lot "younger" how much high frequency
details is happening. Also note the difference in shape between regular skin areas and areas that are shaved for example.

Kind Regards,
Thorsten

(P.S. for reference, yes it is VRayFastSSS2 too hehehe)

Yeah, I've referenced that thread a few times. Great work. Best I could find. It's all in the shader. His model is pretty simple. His textures are also pretty simple. I just have to keep working on nailing this damn shader .

Skin update:

[peterguthrie]

very cool!, love the images in post 10, they really look post-excercise, or ill.

[MoonDoggie]

Everday I get closer and closer. It's really great, looking at those previous images they just look terrible. Here's today's update.
