Tasty enough? :)

Jummy. a good red colour, very slightly pink specularity and a normal map. Maybe a vornoi texture, distance squared, and distorted along the x-axis might be a good starting point.

It's just a reference man ;) A real picture, hehehe :D

This might become handy, since lips are just differently coloured skin ;)

Blender.org says:
"Stress maps can be useful for various things including changing facial textures/materials (such as lips) when they deform and making materials like rubber get more translucent then they are stretched."

I know it's a reference, yet it's a tasty one.
To get things going I uploaded a draft. The specularity gets a big hit when you enable SSS, but if you don't it looks like crap. Anyways the vornoi thing didn't work like I hoped, you might have to draw the cracks in the lips on a texture...
(you were going for lips with rouge on I hope...)

chainz, you have to choose one of the submitted entrys to create the next version of the workflow ;)
Chainz on Jan, 21th - 2008, 08:17 CET
Yes, with rogue ;) Later on when we are done, we can create version without :D
And yes, very detailed, with cracks of course!

This picture is perfect for observing cracks:

HELLO! Anybody!
Is there anyone out there? Where everybody gone? :'(
shadowflier on Jan, 24th - 2008, 02:07 CET
yah I am, but nothing I can add to your work.
though it still doesnt look like real lips, ( too much color and shine for me), but its a good material for a red skin/lether bag :)
The cracks remind me of crocodile skin, not human skin.
Chainz on Jan, 24th - 2008, 10:52 CET
Thanks! That's the comment I was waiting for! :D
snelleeddy on Jan, 24th - 2008, 19:46 CET
The biggest problem is that the SSS (which is needed)kills the spec (which is already kinda high in value). So we need more wetness. I don't know the node system but if you'd add spec to a material with SSS wouldn't you be able to get more spec out of it?
And then there are the cracks, I looked around a bit more but I don't manage to get them done with procedurals.
Chainz on Jan, 25th - 2008, 08:25 CET
Yes... nodes! I'll look into it! :)
On the other hand, do we really need SSS?
And cracks - I think will gonna have to mix few procedural textures like: wood, Musgrave and clouds with voronoi noise.
snelleeddy on Jan, 25th - 2008, 21:16 CET
Yes I think we need SSS, you made me doubt but looking at some models of dannybear I'm pretty shure SSS is a must.
Wood texture works more or less if you turn the XYZ thing to XXZ and ad a colorramp making it thin.
Chainz on Jan, 26th - 2008, 20:05 CET
Who's "dannybear"?? Do you have a link?
