Human's or creatures' eyes have certain level of wetness gathering in the pink skin around the eyeballs that connect the eyeballs to the eyeholes. . If you don't get what I mean so please take a look at some examples by my favourite artists in CGS below :

http://soanala.cgsociety.org/gallery/343797/

This is what I still fail to achieve when modelling eyes. I've read a bunch of eye modelling tutorials but most of them focus on modelling the eyeballs and the wrinkles around the eyes. None of them mentions this pink skin and how to achieve the wetness there. Can anyone please help me with this ?

Thanks.

Its a matter of getting the right reflectivity and specularity. I think when making eyes you have to make sure your materials are on point! And this translates into a lot of tweaking. Unless your so experienced you get luck first try :)

I once read in a book (sorry, forgot which one), the author really modeled the liquid part you're talking about. It's a separate surface, shaped like fillet connecting the eye and the skin.

I remember reading this too and I can't remember where either!

I also rememeber the same artist saying that they used renderable splines to create the wetness that runs along the botton eyelid. I believe they applied a glass-like material to the splines to give the impression of wetness.

I'm not sure what package you are using but the fundamentals are always generally the same. You model two spheres for the eye. One for the cornea layer and the other for the iris layer.

The cornea layer is generally full transparent. Try googling 'Modeling Realistic Eye' and you'll most likely get a free tutorial on how to do this properly.

I think the effect on your first example link was achieved in the post work with a painting package.
