Hey looking good so far...
Since you mentioned the main focus is the colour values, I found this handy image a while ago that points out different temperature regions of the face.
I think some thicker eye brows that catch the light would help it be more noticeable against the skin. Maybe some more color in the ears (or maybe that will be taken care of with SSS?), some of that cool value used on the stubble could work on the top of his head too.
thx guys. yeah, i think for an old guy, he might have lost a bit too much skin tone. the skin needs to be more transluscent i thinks. gonna tweak it a bit more when Im home.
The moles/freckles seem a little blown out from the SS to me. The skin also seems a little too smooth and uniform. I usually find it a bit easier to test out SS materials with just one light, plus mood lighting is always fun. Makes it much easier to see the falloff effects. Anyway, he's very close.
So i started letting more of the tones bleed through (the main purpose is supposed to exaggerate the variances in the tones, thus the older man with more translucency in the skin).
John - It's just a simple Spec Map. Primarily the cavity multiplied by the AO, with additional highlighted emphasis on the T-zone and lips.
They're real-time textures, so I'm constrained to: Coloured Specular, Gloss, Normal and Diffuse.
I think you may have gone a bit too translucent with his skin at this point. The noise pattern on the skin normal feels unnatural IMO- looks less like pores or wrinkles - more like generated noise. I also think the moles and freckles are a bit too uniformly visible- maybe run some cloud masks over those layers.
I Re-calibrated the Specular (particularly on the forehead) eliminating most of the cavity map on the forehead (particularly the skin grain going the wrong direction areas on the forehead).
Cloud masks over the freckles and pock marks worked pretty well (although I averaged them out as I was losing too much of the actual diffuse).

Looking forward to seeing the final. :thumbup:
Thx Zac. I thought I put those regions in, but wondering.. think it's not obvious enough? should I put in more?
Yeah Haikai!
I'll get to the eyebrows in a bit, more varied (it's jsut a flat grey right now with an alpha).
Here's my SSS pass. Think I might have overdone this a bit. Might still need a bit more orange in the ear.
Ok.
