Indigo Renderer Forum

Ok, a updated version of the head rendering.
I blended 3 materials together with some custom painted maps, faking a little SSS by using Diffuse Transmitter.
Also some eyelashes were added and lightning improved a tiny bit, output is still 100% Indigo, no post-pro.

Thanks to the help of fused I now can use the "centralized" Displacement map, here is the quick how-to:

The C value of Disp. Texture needs to be minus 1/2 of B.
So a disp. with value b = 0.01 needs a c = -0.005 to work fine with pure 128 RGB gray not displaced,
higher values (brighter) get etruded in normal direction, and lower values (darker) aginst the normal direction.

I also dropped the bump map totally, here the result:

Wow, this looks like a photograph. Amazing work, Pixie. If I had one criticism it might be that the left side of the face looks a little too bright, but that might simply be on purpose.

If you talk about the face, then its by me not pixie

The Histogram tells me that there is overburning of the image!
Sounds like your monitor needs calibration, the right side of the face is maybe even to dark
the bright/dark style is actually wanted btw...

The left side you mean.

neo0: He said the right side might be to dark -.-

Zom-B: Great work btw, i would love to see it on a diffrent face model aswell, cause i have seen that some materials looks sweet on one model, but breaks apart when applied to another

Ahaha, didnt notice that one, seams neo0 outsmarted me there

This whole material setup is based on 5 textures and 3 materials blended together, I hoped to learn some material workflow that can be applied to every such human situation.

I still have a few plans with this boy:
- blend in a SSS material for (best visible for ears)
- open eyes
- A nice Haircut via Hair2Mesh technique and also some facial Hair.

Good approach with faking sss. I'd paint tatoos on this guy

I remember Ono suggesting the use of a glossy transparent material for basic skin, and with a transmittance layer (the original albedo map probably) for skin color details. Blended with another material of course.

Is there an exponent map ? Probably, but if not you may use the displacement map, with cavities being more shiny than exposed surfaces, unless its the other way around...

I have seen Oren-Nayar materials in the gallery of the head ressource, but the surface details should alleviate the need for this. Hint ?

Ok, after a lot of testing here a pure Glossy Transparent version:

Interesting, thanks Zom-b. There seems to be a bluish tint around the edge. Did you use absorption-layer-transmittance for the skin colour?

Give him a chinstap beard

I say plug him into the matrix.... like Neo

That is one sweet bit of texturing.

How spooky would it be if he opened his eyes and said boo!

Zom-B- very good, material of head in first render looks so real.
