photo-real head WIP

Hello. This is my attempt at photo realistic character modelling. I hadnít done anything photo real before and thought it would be a good chance to challenge myself. I have chosen to model just the head, purely a training exercise for me.



Anyway here is the finished bust as it stands;

Here is an in depth look at the eye. The lashes were created with max's hair modifier and then converted to a mesh (to stop my computer running out of memory). The liquid between the eye and lower eyelid is created with a tube primitive inverted with a mental ray water shader applied to it.

very nice

very nice texturing !! and head !
but i do find some small thing that dosent fit
The eyes of the model seams to open
the eye brow are very sharp in the model and in the reff it is more smoth/soft
and in the reff pic the man has a bit mor chick bones then in the modle

all and all it looks very good
waiting to see what will come out of it

The eye is created with 2 meshes. The inner layer contains the eyeball with iris and pupil modeled into it. This is given a tweaked mental ray fast skin shader to give it slight subsurface scattering. The second mesh is an outer layer containing the lens and outer membrane of the eye. This is given a fully transparent shader with high reflectivity and a slight bump. I used an hdr map as the reflection map on this layer.

Nanush: thanks. Yes, there are a few disparities between the reference and my model, namely his jaw nose and chin. I made the grooves in his chin slightly less symmetrical as I thought it quite a strange feature. I have widened his chin a bit too and shrunk his nose. I guess I've made him slightly more idealized if that makes sense. Your right, the cheek bones are slightly different.

here are some more renders.

The eyes aren't too open. They're too big. Materials look good.

the eyes look quite dead, i would definetly use an sss shader for them, and also im not sure if the refraction is working well. other than that , pretty nice work and nice textures

The eyes may be a little large, but I wonder how much the fov is making them appear even larger. Looking at the ears, I'd normally expect to see more of them. Pulling the fov back would really help with judging the facial features.

Hey dom,

Maybe your reference is really like that so keep that in your mind, but to my eyes some of things seem weird.



Keep going pal!
Cheerio.

menthol:I thought exactly the same thing.

Thanks for the comments The eyes may be appearing slightly large due to the fov on the camera. Here is an orthographic render. I've also tweaked the shape of the head, the nose and the jaw bone.
