Here's my first real effort in MC-POV. Too dark, maybe? I stopped it after
three hours of rendering (two cores) so it wouldn't get too smooth. HDR
lighting seems to work very well with MC-POV. Still needs hair, whiskers,
eyelashes, and something else... Not sure what that might be, but it lacks
texture, or life, or something.

Well, yeah... it's CG and not real. ;^)
Freaky-looking thing, no doubt about it. Made me think of those mannequin's
put into passengers seats of cars to be able to use carpool lanes.
MC-POV...? I guess I saw that mentioned before when speed reading/looking
through these newsgroups. Must be plenty I'm not up to date on these days.
Oh, and maybe the ear needs some redness from light shining through a bit.
That SSS stuff. But I don't know what all you're able to do with that
MC-POV...

What it needs is (1) expression, (2) tiny bits of assymmetry, to make the
figure human.
(1) Expression can be achieved by moving the corners of the mouth, only one
or both; opening the lips a bit, maybe only on the left or the right;
playing with lifting/lowering one or both eye brows; turning the eyes a bit;
turning, bending, shifting the head a tiny bit; lifting one shoulder; etc,
etc... all in very tiny incremental steps. You will see how the figure will
change. Already here a lot of assymmetry is introduced. However:
(2) Very few people have real ssymmetrical faces and those are considered
(unconsciously) as *freakily* perfect, with some sense of unease. So, if you
are using Poser for instance, you can introduce assymmetry by moving the
nose a tiny bit left or right; lifting/loweing one cheekbone a tiny bit;
shifting the lower jaw left or right; etc, etc... By now, you see what I
mean. Just play with all those possibilities and you will be amazed by the
results. Especially those changes that are almost to small to be seen,
result in the highest impact.

Maybe some facial expression...?
Giving the skin a bit of a reflective component can help, too.

It's actually rather limited in what it can do, but it seems quite good at
*that*.
Key features:
- sloooow
- patience always improves the results
- very realistic job at radiosity-like indirect diffuse illumination
- very good job at blurred specular reflections and refractions
- that's about it.
The basic idea behind it is to model diffuse illumination as a very blurred type
of reflection; blurred reflections, in turn, are modeled by adding some jitter
to the reflection, and sampling the whole image over and over again.
Classic lighting with dedicated light sources is disabled; instead, all light
comes from objects with emitting textures or media.
Subsurface scattering should be possible to model with media, just as in
standard POV-Ray, but there's no mechanism to speed it up (it actually would go
against MCPov's basic approach).

Thanks for the good advice. So far I've just been trying to get the proportions
right. That's proving to be difficult enough. I did it in Wings3D so symmetry
is always the last thing to go. If you get rid of that, then you have to make
any changes twice--and hope they come out the same. If I get a chance I'll try
your suggestions, but don't hold your breath. Real life beckons.

This reminds me of the composite pictures you sometime see that are made
by taking a photograph of a face and splitting it down the middle then
combinining each half with its mirror image. The original, real face
usually has no noticeable asymmetry, but the two composites have almost
Jekyll and Hyde differences. It's amazing how different they look.

Introducing assymmetry and/or expression, should be the last things to do,
after you are sure your (symmetrical) model is satisfying and ready for use,
and then work - of course - from copies of that last one :-)
Take your time. We are not in a hurry... ;-)
Anyway, you did a real good job in Wings3D.

Exactly so. The interesting thing is that we are not aware of those
*imperfections* but they certainly give individual personality.
